[Peroneal nerve schwannoma presenting with a peroneal palsy].

Peroneal nerve injury in the lateral aspect of the knee is frequent, commonly dominated by traumatic or compressive etiologies. Tumors, generally synovial cysts, are exceptional causes. We report a case of a 70-year-old women referred for assessment of peroneal palsy syndrome found to be related to peroneal schwannoma in the lateral aspect of the knee. Schwannoma is the most frequent peripheral nerve benign tumor. It is commonly limited to cranial and upper limb nerves. Localization on the lower limbs (sciatic nerve) has been reported in 1 percent of cases. The peroneal nerve localizaton has not been reported to date. We underline difficulties of diagnosis inherent to this particular localization.

[Massive bilateral adrenal hemorrhage: role of imaging].

Bilateral adrenal hemorrhage is a rare and potentially life threatening situation in adults. The clinical presentation is non-specific, and the diagnosis is based on imaging. The purpose of this report is to provide an illustrative case of spontaneous bilateral adrenal hemorrhage that occurred during pregnancy. The sonographic and computed tomographic findings included large bilateral adrenal hematomas with no evidence of underlying malignancy. Since bilateral adrenal hemorrhage is a rare but potentially life threatening situation, prompt laboratory and imaging evaluation are essential and may reduce both morbidity and mortality.

[Rib tuberculosis: value of imaging. Report of 4 cases].

We report 4 cases of tuberculous osteitis of the ribs in patients aged 25 to 60 years. All patients had thoracic CT scan. Two cases presented as multifocal tuberculosis, involving nodes and lung in one case, a costo-verebral joint and lung in the second case. In two patients, the aspect was a misleading pseudo-tumor form with a primitive malignant bone tumor and infiltration of perivertebral and endocanalar soft tissue in one case of costo-transverse joint tuberculosis with neurologial disorder; in the other case, the rib affection presented as a breast tumor due to the involvement of anterior thoracic wall in a 50-year-old woman. In all cases, the radiological aspect was quite extensive osteolysis of the rib with involvement of endo- and/or extrathoracic soft tissue noted as cystic or tissue density. We underline the value of CT scan for a complete investigation of rib lesions, which enables characterization of soft tissues involvement, guiding biopsies and search for associated vertebral lesions.

[Imaging findings in 122 cases of Pott's disease].

Spinal tuberculosis is a frequent skeletal involvement in tuberculosis. We report 122 cases between 1983 and 1998 of Pott's disease explored by plain radiographies in all cases, CT-scan in 22 cases and MRI in 6 cases. The lesion involved one localization in 98 cases, two localizations in 9 cases and multiple localizations in 15 cases. The usual form associating the discal and vertebral involvement was noted in 70%. Unusual forms were seen in 30% of the cases The localizations were: posterior arch (20 cases), centrosomatic (10 cases), suboccipital (4 cases) and subligamentar (2 cases). In addition, the CT scan noted vertebral lesion with soft tissue abscess in all cases and epidural lesion in 9 cases. MRI performed in 6 cases showed epidural lesions in 4 cases: epiduritis (2 cases) and abscess (2 cases). The disco-vertebral puncture-biopsy, performed in 12 cases, confirmed the diagnosis in 7 cases. The diagnosis of Pott's disease was confirmed biologically in 30 cases. Radiographic exploration of Pott's disease is improved by the contributions of CT and MRI which can identify sequestra, perilesional sclerosis and epidural or soft tissue abscesses. Discovertebral aspiration biopsy provides the key to diagnosis.

[Role of computed tomography in pulmonary aspergillosis. 20 cases].

OBJECTIVE: Aspergilloma is the most common form of pulmonary aspergillosis. The purpose of this work was to compare computed tomographic findings with features observed on standard radiographs. PATIENTS AND METHODS: We retrospectively reviewed 20 cases of pulmonary aspergilloma. These patients (mean age 36 years) were followed after cure of pulmonary tuberculosis and consulted for hemoptysis. All underwent computed tomography (CT) and standard radiographic explorations. Serology was positive for Aspergillus in 16 cases and clinical and radiographic findings led to the diagnosis in the 4 others. Both supine and prone positions were used for thoracic CT. Slice thickness was 5 mm without contrast injection. RESULTS: In many cases, standard films evidenced the typical mycetoma seen as a rounded mass of soft tissue density filling a portion of a preexisting cavity or as an air crescent sign, but atypical alveolar opacities, aeric images without aspergillosis colonization and parenchymal destruction predominated in certain cases. The CT-scan demonstrated these features even better revealing the typical cavity in 80% of the cases or an air crescent in 20%. Mobility of the fungus ball was demonstrated by comparison of the prone and supine images. The characteristic CT features allowed certain diagnosis of aspergilloma in 6 patients with atypical radiographic or serologic results. DISCUSSION: Computed tomography is highly contributive to the diagnosis of pulmonary aspergillosis, particularly in case of small cavities that may be missed on the standard films. Recognition of the mobility of the fungal ball enables differentiation from a tumor or infectious lesion. CT is also helpful for guiding transparietal treatment. CONCLUSION: A computed tomography series should be obtained in former tuberculosis patients consulting for hemoptisis.

[Renal angiomyolipoma imaging: report of 9 cases].

PURPOSE: To report the radiological polymorphism of angiomyolipoma (AML). MATERIAL AND METHODS: [corrected] A retrospective series of eight cases of AML explored by US and CT scan. The diagnosis was radiological in seven cases and histopathological in one case. RESULT: Five cases of AML were discovered fortuitously. The tuberous sclerosis of Bourneville disease (TSB) was noted in five cases. The cverage age was 37 years with female predominance noted in seven cases. The AML were multiple in half cases all of thein had TSB. The tumoral size ranged from 0.5 cm and 20 cm. The US showed an homogenous hyperechogenique mass in six cases and heterogenous in two cases. The CT scan showed polymorph parenchymal lesions. The fatty component was detected in seven cases. An intratumoral bleeding was noted in one case. CONCLUSION: The radiological feature of AML is variable, related to tumoral size. It's typical when a tumor of kidney contains fat. An association with TSB is a supplementary argument of diagnosis.

CT features of a voluminous gastric trichobezoar.

We report on the case of a 15-year-old girl with a voluminous gastric trichobezoar imaged by CT. The absence of any attachment of the mass to the gastric wall and the presence of air within the mass are very suggestive for diagnosis.

[Malignant stromal tumors of the small intestine: report of 9 cases].

PURPOSE: Analysis of imaging features of malignant stromal tumors of the small bowel and review of literature. MATERIAL AND METHODS: 9 cases of malignant stromal tumor of the small bowel with histological proof were imaged at US (8 cases), small bowel series (9 cases) and CT scan (3 cases). RESULTS: There were 6 cases of leiomyosarcoma and 3 cases of malignant schwannoma. Tumors involved the jejunum in 3 patients, the ileum in 4 patients, and the duodenum in 2 patients. The main clinical presentation was an abdominal mass (8 cases), which appeared heterogeneous and hypoechoic with eccentric lumen at US confirming its GI origin (7 cases). Small bowel series showed a bulky cavitary mass opacified via a thin fistula (7 cases), an ileo-ileal intussusception (1 case) and enlarged duodenal lumen (1 case). CT performed in 3 cases showed an intraperitoneal mass with soft-tissue density. A communication with the GI tract was noted in 1 case, and in another case, it showed an intestinal intussusception. US guided biopsy performed in 3 cases provided diagnosis in 2 cases (malignant schwannoma, leiomyosarcoma). Tumor growth was exophytic in 8 cases and dumbbell-shaped in 1 case. CONCLUSION: The imaging features of malignant stromal tumors of the small bowel are similar. It varies with the type of tumor growth and its size. The diagnosis may be suggested based on imaging features.

[Malignant bilateral mediastinal teratoma: a case report].

The authors report a case of bilateral malignant teratoma of the mediastinum in a 40 year old female presenting with chest pain. Two separate bilateral soft tissue masses were noted in the mediastinum at imaging. On the right side, the mass was heterogeneous with large calcification and infiltration of the pericardium. On the left side, the mass was well defined, heterogeneous and without evidence of local invasion. The analysis of samples obtained by US guided puncture biopsy and surgical specimen of the two masses confirmed the diagnosis of pluricellular malignant teratoma. Mediastinal malignant teratomas represent 1 to 5% of all mediastinal tumors. To our knowledge, no case of synchronous bilateral mediastinal teratoma has never been reported.

[Heterotopic pregnancy: value of transabdominal sonography].

The authors report a case of an heterotopic pregnancy where the transabdominal US was more useful than endovaginal US. The embryon in this case was located in upper zone of the right iliac fossa, inaccessible to endovaginal US. Both methods are complementary.

[Sellar hemangiopericytoma. Report of a case].

Authors report spontaneous necrosis of a sellar hemangiopericytoma, in a 44 year old man, revealed by a right cavernous syndrome. The initial CT scan showed a right sellar and parasellar spontaneous hyperdense process, intensely and homogeneously enhanced by contrast-agent. This process invaded the right cavernous sinus and extended to the sphenoid sinus. Magnetic resonance imaging showed a lesion in isointense on T1-weighted sequence and slightly hyperintense on T2-weighted sequence, with an intense and homogenous enhancement. The follow-up CT scan performed 6 months later, showed a total necrosis of the lesion. Angiography showed a slightly vascularised process, with mass effect on the carotid and sylvian vessels. The sellar and parasellar localization of hemangiopericytoma is rare. The spontaneous necrosis is exceptional, but it enabled us to distinguish it from meningioma.

[Angiosarcoma of the breast. Radiological aspects. About one case].

Angiosarcoma of the breast in an uncommon entity. The authors report a well documented case of angiosarcoma. The patient, a 23 years old woman, had a voluminous mass of the left breast without inflammation. The evolution was rapidly fatal. Physical examination revealed a large painful breast mass with purplish discoloration cutaneous area in front of the lesion. The palpation revealed a thrill. The mammography had shown an area of increased density in the left breast. A complementary ultrasound examination detected a well circumscribed voluminous mass with hypoechogenic heterogenous echostructure. The Doppler examination detected a venous blood flow in the tumor. This finding was compatible with vascular tumor as angioma or angiosarcoma. The angioscanner showed a peripheral vascular enhancement and a centripetal diffusion of the contrast product. This vascular kinetic is seen commontly in the angioma. Magnetic resonance imaging in the T1 and T2 relaxation times detected an intermediate signal mass with bleeding areas. The patient had had a mastectomy and the histopathologic examination confirmed the diagnostic of angiosarcoma. The radiological aspacts of angiosarcoma of the breast are discussed depending on the literature data.

[Cavernous sinus dermoid cyst with unusual parapharyngeal development].

We report a case of dermoid cyst arising in the cavernous sinus and parapharyngium areas through the foramen lacerum. A 12-year-old girl was hospitalized in October 1966 for progressive intracranial hypertension. CT before a prior surgical intervention in 1994 showed an intracranial process suggesting a dermoid cyst. CT performed in October 1996 showed a temporal process at the left side measuring 8 cm x 5 cm and well circumscribed with a thin wall. This process extended towards the parapharyngium area through the foramen lacerum. The exocranial part measured 4 cm in diameter. The density of the process strongly suggested a mature dermoid cyst with fatty and calcium components. The histology study confirmed the diagnosis of dermoid cyst. The frequency of intracranial dermoid cysts is 2 to 3 times less than that of epidermoid cysts. This is an uncommon process accounting for 1% of intracranial tumors occurring in children. In the sustentorial spaces, the process occurs more frequently in the parasellar area. To our knowledge, exocranial extension has not been reported to date.

[Centrosomatic spinal tuberculosis: radiographic features in 10 cases].

We report a series of 10 cases of centrosomatic tuberculosis of the spine. The mean age of the patients was 36 years. Plain x-rays of the spine showed isolated defects in 3 cases, a defect with wedge fracture in 3 and a wedge fracture alone in 2. A sequestrum was found in 2 cases and bony condensation around the defect in 6. A CT scan performed in 3 cases showed, in addition to the bone lesions, a perilesional bony condensation in all cases. Soft tissue abscess formation was noted in 1 case and epidural involvement in the 2 others. MRI performed in 2 cases evidenced an alteration of the vertebral body signal with localized anterior epiduritis at the site of a small epidural abscess. CT scan and MRI contribute usefully to the radiographic diagnosis of centrosomatic tuberculosis, evidencing sequestra, bony condensation at the periphery of defects, and the presence of soft tissue abscesses and or epidural involvement. When these signs are absent, the differential diagnosis may be difficult with other causes of tumor formation, requiring vertebral biopsy.
