[MRI and pituitary adenoma].

Pituitary is the most important gland of the organism which can be affected by many diseases, especially by adenomatous processes. Classically macroadenoma, microadenoma and picoadenoma are described, according to the size of the pituitary adenoma. The diagnosis of microadenoma was long considered a highly difficult task and that of picoadenoma was impossible by computed tomography. Recently, the high resolution of multiplanar MRI has enabled the diagnosis of microadenomas measuring less than 3 mm (picoadenoma). For macroadenoma, MRI not only contributes to diagnosis but is particularly important to assess the extension and to detect possible complications. The aim of our study is to illustrate MRI features in pituitary adenoma.

[Adrenal gland hemangioma: a case report].

Hemangioma is a benign vascular tumor composed of angioblastic cells. The adrenal gland localization is very rare, with only fifty cases reported in literature. We report a case of adrenal gland hemangioma diagnosed in a 55-year-old woman who presented a cervical neoplasm. The non-specific imaging features, the tumor size and the clinical context led to mandatory surgical resection. The pathological examination established the diagnosis of adrenal gland hemangioma.

[Cavernous hemangioma of the breast: a case report].

Cavernous hemangiomas of the breast are uncommon. Clinical diagnosis is rather difficult. Generally there are coincidental microscopic findings. We present a case of a 67-year-old woman which commenced as a 6 cm palpable mass of the right breast. The use of mammography, ultrasound and MRI facilitate diagnosis. Large surgical excision of the lesion was performed and histology allowed to find a cavernous hemangioma without cellular atypia.

[Pterygoïdien hydatid cyst].

INTRODUCTION: The cervico-facial hydatid cyst is rare. It accounts for 1% echinococcisis locations and usually involves the salivary gland and the thyroid. Pterygoid muscle involvement is exceptional. CASE REPORT: We report the case of a patient presenting a hydatid cyst of the pterygoid muscle. The patient presented a non specific progressive tumor syndrome. DISCUSSION: This case illustrates the importance of CT scans. Surgery is always required. We emphasize the risk of complications when the diagnosis is missed.

[Solitary eosinophilic granuloma of the orbit: a case report].

The authors report a case of eosinophilic granuloma involving the roof and the lateral wall of the left orbit in a 5-year-old boy. The clinical presentation and especially the imaging features (computed tomography and MRI) suggested a malignant tumor and the final diagnosis was obtained by fine needle aspiration biopsy with histopathologic examination. Despite its alarming radiologic appearance, there was spontaneous healing of the eosinophilic granuloma with restitution ad-integrum of the bone.

[Neurosarcoidosis as the first manifestation of sarcoidosis: diagnosis difficulty. A case report].

Clinically apparent involvement of the nervous system occurs in a relatively small number of patients with sarcoidosis. The diagnosis of neurosarcoidosis is often difficult and particularly in patients who lack either pulmonary or systemic manifestations of sarcoidosis. Furthermore clinical and imaging features of neurosarcoidosis are extremely variable. We report a case of neurosarcoidosis which had been considered and treated at first as tuberculosis. Only the occurrence, two years later, of pulmonary manifestations of sarcoidosis enabled the diagnosis.

[Right tracheal bronchus associated with tuberculosis pneumonia. A case report].

Right tracheal bronchus is a rare almost always asymptotic congenital malformation. We report a case of right tracheal bronchus associated with pneumonia tuberculosis of the apical segment of the upper right lobe. We describe the characteristic of this malformation and stress the role of computed tomography scan to detect these anomalies.

[Hemoperitoneum secondary to the rupture of superficial veins of a uterine leiomyoma].

The most frequent cause of gynaecological hemoperitoneum is ruptured ectopic pregnancy. An uncommon cause of hemoperitoneum is rupture of uterine leiomyoma. We report one case of massive intraperitoneal hemorrhage and hypovolemic shock due to ruptured uterine leiomyoma vessels. The patient was treated with myomectomy and the postoperative course was uneventful. These case suggest that massive intra peritoneal hemorrhage associated with uterine leiomyoma should be considered in women with hypovolemic shock and pelvic mass.

[Abdominal actinomycosis. Report of 4 clinical cases studied with radiography].

We report 4 cases of pathologically proven abdominal actinomycosis. US and CT demonstrated an infiltrative abdominal mass with ill-defined margins and heterogeneous enhancement after IV contrast. The ileo-cecal region was involved in one case; the mass appeared following cholecystectomy and recurred 3 years after surgical resection in one case; and no predisposing factor was identified in the 2 other cases. In one of these, recurrence was observed 12 years after the first episode. Actinomycosis must be included in the differential diagnosis of invasive abdominal lesions with "malignant" appearance.

[Mucoepidermoid carcinoma appearing synchronously in the lacrimal and salivary glands].

An 86-year-old woman consulted for a swelling on the palpebral side of the upper eyelid that she had discovered 4 months earlier. Physical examination also revealed a parotid nodule on the same side. Clinical and radiological findings were in favor of a malignant lacrimal tumor. The parotid localization would correspond to either a lymph node metastasis or an intraparotid metastasis or to a primary parotid tumor with salivary metastasis; We discuss these hypotheses in light of the epidemiology, history and clinical and pathology findings.

[Radioclinical profile of cardiopericardial hydatid: report of 17 cases].

Hydatid cysts concerning the heart are rare, accounting for 0.5 to 2% of all hydatic sites. The risk of serious complications in this location makes rapid diagnosis and surgical treatment essential. The aim of our study is to clarify the role of imaging in the diagnosis of the disease and to propose an adequate strategy. We report on 17 patients who underwent surgery for cardiopericardial hydatid cyst in the cardiovascular and thoracic unit of Sahloul hospital in Sousse from January 1988 to December 1998. Clinical investigation included in all cases chest X ray, ECG and ultrasonography (US). A computed tomography (CT) scan was performed in 14 cases, magnetic resonance imaging in three cases, transesophageal US in five cases, and coronary angiography in fsix cases. Examination for other hydatic sites was realized in all cases, and brain CT was performed in four cases. The hydatid cyst was variably localized in the left ventricle wall (five cases), the right ventricle (five cases), the pericardium (five cases), the interventricular septum (four cases), the right auricle (one case) and the left auricle (one case). The existence of other cardiac hydatid sites was found in 12 cases. All patients underwent surgery. Outcome was favorable in 14 cases, with a mean of 3 years and 5 months survey. Three patients died. The combination US-CT scan allowed a precise topographical inventory, reducing the need for MRI to the complicated cases and to the rare cases of inconclusive results by US-CT scan.

[Subcapsular hematoma complicating acute pyelonephritis].

Spontaneous subcapsular renal hematoma is rare and essentially associated with malignant, or benign tumor vascular diseases, inflammatory processes. In few cases, no cause was detected. We observed one additional case in a diabetic women. She presented fever, and bilateral flank pain. Ultrasonography showed bilateral subcapsular hematoma. Computed tomography confirmed these findings and demonstrated multiple area of acute focal pyelonephritis.

[Value of imaging in the assessment of malignant fibrous histiocytoma of the soft tissues].

Malignant fibrous histiocytoma (MFH) is a rare and potentially highly malignant sarcoma. The authors report 6 cases of MFH in various sites: two in the chest wall, one in the pelvis, two in the gluteal zones and one on the scalp. Ultrasonography and computed tomography were the main imaging methods used in the assessment of the structure and extension of the tumor. A poor prognosis was noted in four cases: death within a few months in the two thoracic sites, recurrence in the pelvic and scalp lesions, radical surgery allowed recovery in two cases. A review of the literature showed that MRI and CT are complementary in the initial staging and follow-up of these patients.

[Pyogenic abscess of the psoas].

11 cases (7 primary and 4 secondary) of pyogenic psoas abscesses are reported. In all cases Staphylococcus aureus was isolated on blood culture or pus drained under ultra-sonographic control. US is very useful for diagnosis and the follow up of psoas pyogenic abscesses. Percutaneous aspiration and drainage of psoas abscesses under ultrasonographic control combined to antibiotherapy is an effective therapeutic procedure. Our experience suggests that antibiotherapy alone is an effective therapy of presuppurative pyogenic psoas abscesses and even in collected and non complicated primary psoas abscesses.

[Bone anomalies in von Recklinghausen disease].

28 cases of neurofibromatosis are reported. Principals bone anomalies are reviewed. The skeletal manifestations are numerous and varied. These anomalies interest specially cranial vault, spheno-orbital area and vertebral spine. It is imperative to keep in mind skeletal manifestations because neurologic and cutaneous signs can be absent.
