Cavernous hemangioma of the parietal bone. A case report.

Intraosseous cavernous hemangiomas are a rare finding in the calvarium. It is a benign tumors arising from the intrinsic vasculature of the bone. We report one case observed in a 31 year-old female, presented with a progressive left parietal mass. A plain X-ray of the skull and cranial CT-scan showed a osteolytic lesion in the left parietal bone. Surgery consisted of total resection of the lesion and cranioplasty. The postoperative course was uneventful. Histological study revealed a cavernous hemangioma of the diploe. In view of this observation and the literature review, clinical; radiological and therapeutic aspect of this rare entity are discussed.

[Chronic lumbar pain considered to be "nephretic colic" after 7 years, due to a thoracic disc herniation at T10-11].

The authors report the case of a 35-years-women with a thoracic disc herniation, who presented with seven years history of episodic acute ureteric colic. An early diagnosis of a spinal disc herniation was made difficult by the absence of neurological findings. Imaging studies showed no lesion in the genito-urinary tract. Magnetic resonance imaging demonstrated a postero-lateral disc herniation at T10-T11 level. The pain disappeared immediately after surgery decompression. A literature search showed that acute ureteric colic associated with a lower thoracic disc herniation has not been previously reported.

Cerebellar liponeurocytoma (lipomatous medulloblastoma).

Liponeurocytoma (lipomatous medulloblastoma) is an uncommon clinicopathologic entity. We report a case of cerebellar liponeurocytoma in an adult and attempt to better characterize this uncommon lesion. A 43-year-old woman presented with symptoms and signs of increased intracranial pressure and cerebellar dysfunction. CT and MRI showed a heterogeneous well-circumscribed mass in the left cerebellar hemisphere with hydrocephalus. Complete surgical excision of the tumor was accomplished through a suboccipital craniotomy. Pathological examination with immunohistochemical study revealed a medulloblastoma with neuronal, astrocytic and lipomatous differentiation. Postoperative radiation therapy was given. After surgery, the patient was followed up for a 16 month-period; symptoms improved dramatically and no evidence of tumor recurrence was found. Careful analysis of the histopathological and immunohistochemical studies correctly identifies liponeurocytoma (lipomatous medulloblastoma). To our knowledge, only 16 cases have been reported. Although this lesion appears to have a better prognosis than the conventional form of adult medulloblastoma, complete surgical removal with postoperative radiation therapy is recommended.

Non-dysraphic intramedullary spinal cord lipoma. A case report.

Non-dysraphic spinal cord lipomas are rare benign lesions, accounting for approximately 1% of all spinal cord tumors. Patients usually present with long histories of disability followed by rapid progression of their symptoms. Presenting symptoms include spinal pain, dysesthesic sensory changes, gait difficulties, weakness, and incontinence. Magnetic resonance imaging is the examination of choice. The T1- and T2-weighted images show increased and decreased signal intensity, respectively. The goal of intervention is decompression and generous debulking following by duraplasty. Early diagnosis of spinal cord lipomas and early surgery is advanced prior to irreversible disease progression. One new case of true non-dysraphic cervicodorsal spinal cord lipoma is reported.

[Giant epidermoid cyst of the skull with extra and intracranial extension. A case report].

Intradiploic epidermoid cyst of the skull is a rare clinical entity that can exceptionally grow to a large size with intracranial extension. The authors report the case of a 38-year-old man with a giant epidermoid cyst of the parietal bone with extra and intracranial extension, presenting with focal neurological symptoms. The diagnosis was suggested at imaging (skull radiographs, CT and MRI), and confirmed at histology. Complete removal of the cyst and its capsule was performed followed by cranioplasty. Postoperatively, the patient was discharged free of symptoms. CT scan provides good evaluation of the bony lesion and may suggest intracranial extension. MRI is superior for evaluation of cerebral compression. The pathogenesis, clinical presentation, diagnostic evaluation and therapeutic management of these rare lesions are reviewed.

[Tuberculous osteitis of the posterior vertebral arch: case report].

The authors report an unusual case of spinal tuberculosis involving the posterior arch of T12 without disk lesion in a 20-year-old woman presenting with posterior compression of the spinal cord. The diagnosis was suggested at CT and MR imaging and confirmed by histological study after surgical resection. CT provides good evaluation of the bony lesion and may suggest intraspinal extension. MRI is superior for evaluation of cord compression. The patient improved after surgical and medical treatment. The imaging features of this entity are reviewed.

Primary intradural extramedullary ependymoma: case report and review of the literature.

STUDY DESIGN: The authors report the ninth case in the literature of a primary intradural extramedullary ependymoma of the spinal cord. OBJECTIVE: To discuss surgical treatment and the physiopathologic hypothesis of this localization on the basis of the results of the present study and a review of the literature. SUMMARY OF BACKGROUND DATA: Ependymoma is a glial tumor known to arise in the central nervous system. Intradural extramedullary location of this neoplasm has been exceptionally described previously. METHODS: A 43-year-old woman was admitted to the authors' institution with an history of progressive paraplegia. Neurologic examination showed sensory loss below T1 and bladder disturbances. Magnetic resonance imaging revealed an enhanced thoracic intradural extramedullary tumor, extending from T1-T8. No other lesion in the central nervous system was found. Emergency surgical resection was performed. RESULTS: Surgery gave confirmation of an encapsulated extramedullary tumor without attachment to the spinal cord or to the dura mater. Total removal was achieved under microscope. The postoperative course was uneventful, with complete neurologic recovery 3 months later. The patient has been well for 24 months of follow-up evaluation, without evidence of recurrence on magnetic resonance images. Histologic examination revealed the tumor as a benign ependymoma. CONCLUSION: The encapsulated feature, the lack of attachment to the central nervous system, and the absence of other neoplastic processes within the brain or the spinal cord suggested that this lesion is a primary tumor developed from ectopic ependymal cells.

[Epidural hydatid cyst of the posterior fossa].

We report a case of epidural hydatid cyst in the posterior fossa in a 5-year-old child. The disease was revealed by raised intracranial pressure with torticollis. The diagnosis was based on the brain CT scan and MRI, and confirmed surgically. The course was uneventful. Cranial epidural hydatid cysts are very rare: only 18 cases have been reported previously in the literature.

[Spinal epidural angiolipomas: a rare cause of spinal cord compression. A report of 8 cases and review of the literature].

Extradural spinal angiolipomas are rare benign tumors containing vascular and mature adipose elements. We report 8 cases of spinal epidural angiolipomas in 6 females and 2 males. In 7 cases, the clinical manifestation was a progressive spinal cord compression and one case had a regressive paraparesis mimicking a multiple sclerosis. In the 8 cases, the localization was thoracic with an extradural complete type of contrast block in 2 cases and partial in 5 cases. The myelo-CT achieved in 7 cases and the magnetic resonance imaging done at our last case revealed a fat-containing epidural tumor. The tumors were removed in all cases through a laminectomy with a successful outcome after an average of 9 years (range: 6 months-12 years). Sixty-seven similar cases in the international literature are reviewed. A total of 75 cases have been studied: 45 women and 30 men with a mean age of 46.3 years (range: 6-73), presenting a progressive spinal cord compression in 68 cases and in 7 cases a regressive paraparesis mimicking a multiple sclerosis. Myelography shows an extradural compression of the thecal sac. MRI is nowadays the imaging modality of choice for the diagnosis of these lesions. The surgical removal often easy of the epidural spinal angiolipomas permit a fast recovery. The etiopathogenesis of this process is still controversial between the dysembryogenetic and malformative hypothesis.

[Intracranial granuloma: a rare complication of ventricular derivation. Case report].

We report an unusual case of cerebral granuloma secondary to ventriculoperitonal shunt. A 17 year-old patient presented with choreoathetoid movements of the left upper limb five years after a ventriculoperitoneal shunt and cerebellar pilocytic astrocytoma excision procedure. MR imaging showed mass lesion in right basal ganglia area surrounding ventricular catheter which seems to be neoplastic. Stereotactic biopsy of the lesion with histologic study revealed a granuloma. Ventricular catheter was removed and patient improved clinically and lesion disappeared completely on MRI control. At literature review, we found only 4 similar cases. Clinical and radiological findings (CT scan and IRM) are described as well as pathogenic mechanism involved. Therapeutic procedure should be limited to catheter removal without granuloma excision.

Craniocervical junction tuberculosis in children.

A case of tuberculosis of the craniocervical junction in an eight-year-old is reported. Presenting symptoms were painful torticollis, dysphagia, and tetraparesis. Computed tomography and magnetic resonance imaging findings strongly suggested the diagnosis, which was confirmed by peroral aspiration of a retropharyngeal collection. Management was by immobilization and antituberculous agents. Surgery was not performed. After one year, the outcome was highly satisfactory.

[Recurrent bleeding of thalamic cavernous angioma under hormonal treatment. A case report].

A case of recurrent bleeding from a probable left thalamic cavernoma in a 26 year old woman taking hormonal treatment is reported. Four episodes of bleeding were clinically and radiologically documented, prior to her referral to our institution. Interestingly, each episode occurred three weeks after starting hormonal treatment, dydrogesterone, desogestrel ethinylestradiol, chlormadin, nomegestrel acetate). The patient was not operated because of the deep situation of the cavernoma which was remote from the thalamic surface within the third ventricle. There was no recurrent bleeding after the onset hormonal treatment was discontinued. Although no similar case has been found in the literature, we believe that this case gives further argumentation in favor of a role of hormonal factors influencing the biological behavior of cavernous angiomas which has been previously suggested in pregnant females with bleeding cavernous angiomas.
