1/2074. endodermal sinus tumor of the pineal region: case report.

    This is a case report of an endodermal sinus tumor occurring in the pineal region of a 12-year-old Caucasian boy. Germ cell tumors of this type demonstrate a selective overgrowth of yolk sac endoderm associated with extraembryonic mesoblast and arise perferentially in the gonads of young children. This is the ninth known report of this tumor in the world literature. Its occurrence in the posterior third ventricle again confirms that pineal region germ cell tumors are histologically analogous to germ cell tumors originating in the gonads. A disturbance in the region of the primitive streak is thought to account for the exclusive midline location of this tumor in extragonadal sites. This patient was treated with a combination of vincristine, actinomycin D, and cyclophosphamide, and concomitant cobalt irradiation. For endodermal sinus tumors in the pineal region, this combination appears more effective than previously reported treatment by irradiation alone.

2/2074. Brain metastasis from prostatic carcinoma.

    Between 1959 and 1971 there were 91 patients with clinically diagnosed prostatic carcinoma who were autopsied at Roswell Park Memorial Institute. In four of these 91 (4.4%) intracerebral metastasis were found at autopsy, but only in one of these four was the diagnosis arrived at pre-mortem. This report describes the diagnosis and management of intracerebral metastasis from prostate carcinoma. It appears, on the basis of our initial experience, that the clinical diagnosis of this entity deserves more frequent consideration.

3/2074. Intracranial hemorrhage due to cerebral metastasis of lung cancer - a case report.

    lung cancer often metastasizes to brain. However, hemorrhage of the metastatic lesions is uncommon. We report a case of a 68-year old man with lung cancer who underwent right upper lobectomy of the lung and presented in 15 months with a cerebral hemorrhage from a metastatic lesion of the brain.

4/2074. Complete paraplegia due to multiple intracerebral and spinal cavernomas.

    We report on a 29-year-old male patient with multiple intracerebral and spinal cavernomas. Bleeding in the thoracic cord at admission and additional bleeding which occurred 12 days later in the cervical cord resulted in complete paraplegia below thoracic level 4 (Th4). Four years earlier multiple cerebral cavernomas had been diagnosed by magnetic resonance imaging (MRI). Based upon reported cases in the literature multiple intracerebral and spinal cavernomas are exceptional. Additionally, the clinical presentation in our case is uncommon.

5/2074. Lymphomatosis cerebri presenting as a rapidly progressive dementia: clinical, neuroimaging and pathologic findings.

    Primary central nervous system lymphoma (PCNSL) usually presents with clinical and neuroimaging findings consistent with single or multiple intracranial mass lesions. On cranial magnetic resonance imaging (MRI), such lesions are nearly always contrast enhancing, reflecting disruption of the blood-brain barrier at the site of tumor nodules. We describe 2 cases from the UCLA Medical Center who developed a rapidly progressive dementia due to extensive gray and white matter cerebral lesions involving much of the brain. In the patient who came to autopsy, widely infiltrating, focally necrotic B-cell plasmacytoid lymphoma was noted throughout the cerebral neuraxis. MRI findings in case 2 were consistent with diffuse lymphomatous brain infiltration without mass lesions, which was biopsy proven. We conclude that PCNSL may occur in a diffusely infiltrating form which may occur without MRI evidence of mass lesions or blood-brain barrier compromise. We refer to this entity as 'lymphomatosis cerebri' and add it to the differential diagnosis of a rapidly progressive dementia.

6/2074. Cervicomedullary astrocytoma simulating a neuromuscular disorder.

    A 12-year-old male developed progressive proximal upper extremity weakness over a 3- to 4-year period. The clinical findings of proximal upper extremity weakness and atrophy, prominent scapular winging, and no sensory deficits or upper motor neuron signs suggested a neuromuscular disorder. electromyography was consistent with a chronic denervating disorder involving the upper cervical anterior horn cells or their axons. A cervical magnetic resonance image revealed a large intramedullary mass extending from the inferior aspect of the fourth ventricle down to the level of T2. A biopsy of the lesion was consistent with a low-grade astrocytoma.

7/2074. Successfully treated central nervous system Burkitt's lymphoma with minimal extraneural disease in a child.

    Burkitt's lymphoma, the most common childhood non-Hodgkin's lymphoma, usually presents with abdominal tumors. central nervous system (CNS) involvement in Burkitt's lymphoma is mostly secondary to advanced systemic disease, rarely with brain parenchymal lesions, and was previously recalcitrant to treatment. We report an unusual case of CNS Burkitt's lymphoma with minimal extraneural disease. This 10-year-old immunocompetent boy presented with increased intracranial pressure and seizures and was found to have multifocal intracerebral lesions on brain imaging studies. cerebrospinal fluid studies confirmed the presence of Burkitt's lymphoma cells. Abdominal computed tomography showed bilateral nephromegaly with left intrarenal lesions that disappeared after three doses of intravenous dexamethasone. The patient was treated for 6.5 months according to the LMB 89 group C protocol of the French Pediatric Oncology Society. The response was brisk and complete. The patient has been disease free for more than 4 years, and is believed to be cured.

8/2074. Secondary glioblastoma remarkably reduced by steroid administration after anaplastic transformation from gliomatosis cerebri--case report.

    A 45-year-old female presented with gliomatosis cerebri manifesting as hemiballismus-like involuntary movement in the arm, motor weakness in the leg, and hypesthesia in her left side. Computed tomography showed only diffuse swelling of the right cerebral hemisphere, but T2-weighted magnetic resonance imaging revealed a diffuse lesion spreading from the right thalamus to the temporal, parietal, and occipital lobes on the same side. No abnormal enhancement was recognized. cerebral angiography showed no specific finding. A right occipital lobectomy was performed to confirm the diagnosis of gliomatosis cerebri. Anaplastic transformation was recognized 5 months later. The disease did not resolve with radiation or interferon administration, but steroid therapy achieved remarkably effective tumor regression. The patient died due to pneumonia. autopsy showed the features of diffuse glioblastoma. Steroid therapy may be an effective treatment for gliomatosis cerebri before the terminal stage.

9/2074. craniopharyngioma of the pineal region.

    Craniopharyngiomas generally develop either in the suprasellar region or in both suprasellar and intrasellar regions. We report on a nontypical location of the craniopharyngioma in the pineal region. An 8-year-old boy was admitted to the department of pediatric neurosurgery in a grave condition. An MRI scan of the brain was performed after the neurological examination and revealed a large neoplasm situated in the posterior part of the III ventricle and in the pineal region, measuring 8.5x6.5x5 cm. The size of the tumor and its location meant it was occluding three ventricles, with subsequent hydrocephaly. Total removal of the tumor was carried out. Microscopic investigation of the tissue removed showed the typical structure characteristic for craniopharyngioma of the adamantinomatous type. Results of a consultation 6 months after the operation revealed that the patient was feeling well, attending school regularly and had finished the first semester with excellent results. On control MRI scan no tumor was found.

10/2074. Successful removal of a hemangioblastoma from the medulla oblongata: case report.

    Hemangioblastomas are histologically benign tumors that occur exclusively within the neuraxis, most commonly in the posterior fossa. They are typically cystic tumors located in the cerebellum. Excision of the vascular mural nodules leads to cure. brain stem lesions are rarely reported. Surgical extirpation of a solid brain stem hemangioblastoma is relatively risky and requires precise microsurgical techniques. We present a woman with a hemangioblastoma embedded in the medulla oblongata. This 33-year-old woman presented with occipital headaches and sensory ataxia. Complete and detailed preoperative imaging studies were followed by successful microsurgical excision of the lesion. The patient recovered completely within 2 weeks after the operation except for mild paresthesia of the legs. Preoperative magnetic resonance imaging and cerebral angiography provided important information regarding the nature, location, and blood supply of this lesion, which facilitated its total removal. The importance of intraoperative identification and control of the feeding artery of the tumor is emphasized.
