We report on diagnosis, treatment and clinical course of a solitary schwannoma of the trigeminal nerve with consecutive metastatic spread in a 45-year-old woman. The patient presented a temporal lobe syndrome with psychomotor seizures. Trigeminal nerve function was intact apart from a transient hypaesthesia in the mandibular branch. Assuming a meningioma the tumor was removed via a temporal approach. Secondary to the definitive histological diagnosis radiation therapy was performed. After that the patient was symptom-free. 4 months later a large recurrent tumor was found involving the cavernous sinus and the pterygopalatine fossa. In a second operation the tumor was resected intra- and extradurally through an infratemporal preauricular approach in cooperation with an oral and maxillo-facial surgeon. At this time multiple pulmonary metastases developed showing no response to polychemotherapy (EVI). The patient died 13 months after onset of the disease. Hitherto, only 5 cases of a primary malignant schwannoma of the trigeminal nerve have been published in the world literature.

The fate of tuberous sclerosis (TS) patients after renal transplantation (RT) for end-stage renal failure remains to be defined. We report three patients with a posttransplantation follow-up averaging 54 months and review 6 previously published cases. Three women, aged 27-46 years, received a cadaver kidney 26-67 months after starting dialysis. None had mental retardation, 2 had suffered from seizures during infancy and 2 had intracranial calcification; neurological involvement was equally mild in the 6 reported patients. Currently, 16-84 months after RT, our 3 patients are fully rehabilitated with a well-functioning graft (serum creatinine 1.2-1.7 mg/dl). Results of RT are also satisfactory in the 4 other reported cases for whom a follow-up is available, except for 1 death unrelated to the initial disease. Neurologic disorders did not progress. Renal cell carcinoma was discovered in one removed kidney, and cells suggestive of malignant transformation in another case. No metastases were discovered up to 4 years later. No neoplastic transformation was observed up to 7 years after RT in the 3 patients who retained their native kidneys. TS patients with end-stage renal failure are good candidates for RT. The probably small risk of neoplastic transformation of native kidneys warrants a close monitoring by CT scan of the few patients who have not undergone bilateral nephrectomy.

We reviewed retrospectively a series of 100 inpatients with onset of epileptic seizure after the age of 60. All of them were investigated by EEG and 96 by CT scan. The most frequent cause of seizure was previous stroke, with 25 cerebral infarcts and 5 hemorrhages. Neoplastic lesions were present in 18 cases, with glioma (high grade), meningioma and metastases in the same proportion. Other etiologies included toxico-metabolic (18 cases), post-traumatic (9 cases), cerebral atrophy (4 cases) and miscellaneous (14 cases). The causes of seizure remained unknown in 7 patients, of whom 6 had focal signs in either clinical examination or EEG. Focal seizures (with or without secondary generalization) accounted for 65% of all cases and generalized seizures for 35%. The EEG was normal in 12 patients and abnormal in 88, with diffuse slowing in 55 patients and focal signs in 70 (some patients had both diffuse slowing and focal signs). Fourteen patients presented status epilepticus. Ten died during hospitalization. We conclude that epileptic seizure with onset after age 60 is nearly always symptomatic, and neuroradiologic investigations are necessary in the search for cerebral lesions. In our study, the prevalence of "idiopathic epilepsy" is lower than previously described.

Eighteen cases of insulinoma treated at the Instituto Nacional de la Nutricion in Mexico City are presented. The cases were operated on between 1959 and 1988, and include 10 women and 8 men with a mean age of 38. The duration of symptoms ranged between 4 and 96 months with a median of 27; 78% of the patients had neuropsychiatric symptoms, 61% seizures, and 55% loss of consciousness. One of the patients had evidence of type I multiple endocrine neoplasia. Diagnosis was established in all the patients with the demonstration of Whipple's triad and also with an elevated insulin determination in the last nine patients. In six cases the insulinoma was enucleated; in two a Whipple procedure was performed; in nine a distal pancreatectomy and in the remaining patient only resection of hepatic metastases; 67% of the tumors were diagnosed as benign solitary adenomas, 16.5% as carcinomas and the same number as hyperplasia. Operative mortality was 5.5%, and morbidity 44%. The three carcinomas survived 6, 8 and 36 months. Disappearance of the hypoglycemic symptoms was obtained in 93% of the cases of adenoma and hyperplasia.

From 1980 to 1987, 162 consecutive children with soft tissue and osseous sarcoma were reviewed to determine the frequency and types of neurologic complications seen. Neurologic complications occurred in 43 of 162 (26.5%) patients. Children with poorly differentiated sarcomas and rhabdomyosarcoma were more likely to have neurologic complications, which occurred in 39% of patients at risk. The types of complications seen included: metastatic spinal cord compression (11%); symptomatic peripheral neuropathy (10%); intracranial metastatic disease (7.5%); seizures (6%); and acute and chronic methotrexate-related neurologic dysfunction (2.5%). Spinal cord compression frequently occurred early in disease whereas brain metastases was almost always a late finding. Symptomatic peripheral neuropathy occurred primarily in children with rhabdomyosarcoma and Ewing's sarcoma. The advent of increasingly successful therapies for children with sarcoma and the frequency of severe neurologic complications indicate that a heightened level of surveillance for neurologic compromise is required.

Breast carcinoma has a high predisposition to metastasize to the brain parenchyma or spinal epidural space with development of progressive neurological symptoms and signs and frequently death of the patient. We report 8 patients with known breast cancer who developed neurological symptoms attributable to an intracranial meningioma and 1 patient who developed spinal cord dysfunction resulting from a thoracic meningioma. The removal of the meningiomas resulted in return of normal neurological function in all patients. At follow-up, all our patients are alive without evidence of meningioma or breast carcinoma recurrence, except 1 patient who died of a metastatic malignant melanoma. This clinical association requires repeated emphasis because of the potential benefit in management of patients with suspected metastatic disease. We have reviewed and summarized the reported literature and added our 8 cases. The mean age of presentation before the second tumor was 6 years. Breast carcinoma was diagnosed first in 85% of cases. The clinical symptoms of the meningiomas were focal neurological signs in 50% of the patients, raised intracranial pressure in 40%, and a seizure in 10%.

The authors reviewed the records of 2261 patients with histologically proven cervical cancer. Among the 1042 patients with carcinoma in situ, four neurologic complications occurred (0.4%), including three strokes and one seizure. None of the neurologic complications were related to cervical cancer. Among the 1219 patients with International Federation of Gynecology and Obstetrics (FIGO) Stage I or greater disease, 99 neurologic complications occurred (8%). Metastatic neurologic complications were twice as common as nonmetastatic neurologic complications and included lumbosacral plexopathy (50 patients), peripheral nerve compressions (eight patients), spinal cord compressions (two patients), and brain metastases (six patients). Nonmetastatic neurologic complications were less frequent and included stroke (11 patients), encephalopathies (three patients), infectious complications (two patients), effects of therapy (six patients), and seizures (11 patients). In conclusion, neurologic complications are rare in cervical cancer and virtually nonexistent in Stage 0 disease. Metastatic neurologic complications were more common than nonmetastatic complications and lumbosacral plexopathy caused by retroperitoneal lymph node metastases was the most common neurologic complication.

The clinical and computed tomographic findings in 25 patients with parietal lobe hematomas are discussed. Six patients had anterior-lateral parietal hematomas (18 to 36 mm). These patients were normotensive. No etiology was delineated even when angiography was utilized. Six patients had medial parietal hematomas (12 to 24 mm) with extension to the thalamus. Two patients were normotensive and six were hypertensive. Three patients had posterior parietal hematomas (10 to 18 mm). These patients were hypertensive. Eight patients had parietal hematomas extending to the temporal and frontal region (30 to 60 mm). Three of these patients died. Four patients were normotensive and four were hypertensive. One of these normotensive patients had cerebral metastases. Two patients had parietal hematomas which extended to the occipital region (20 to 34 mm). These patients were normotensive. Peripheral rim enhancement was demonstrated on follow-up CT scan (performed 2 to 4 weeks after the initial study) in 14 of 21 cases. On follow-up CT of the 21 surviving patients with parietal hematomas (excluding the case due to metastases) performed more than 4 weeks after the clinical ictus, 14 appeared hypodense and 7 appeared isodense. Residual neurological deficit and recurrent seizures were more frequent if the hematoma "aged" to a hypodense appearance.

We report a case of limbic encephalopathy clinically characterized by a progressive amnestic syndrome and many EEG seizures mainly localized on the left temporal area. Biological investigations revealed diabetes mellitus and a syndrome of inappropriate antidiuretic hormone secretion (IADH). Haemodynamic and metabolic studies by positron-emission tomography showed an important increase in cerebral blood flow (CBF) and cerebral metabolic rate of oxygen on the left anterior temporal region precisely where the electrical seizures were recorded. Nine months later, severe disorders of memory and a dramatic decrease in CBF and CMRO2 on the same area region were present. At autopsy, a small size oat cell bronchial carcinoma was found with metastases in two small adjacent lymph nodes. Neuropathological examination showed atrophy (neuronal loss, protoplasmic gliosis) in the amygdala; where there was in addition an area of nodular gliosis. The hippocampus and parahippocampal gyrus lesions were severe on the left and moderate on the right side. The authors discuss the nosology of their case in the paraneoplastic syndromes and, with a review of the literature, the role of ADH and cellular hyperactivity in the pathogenesis of specifically localized neuronal alterations.

Disorders of calcium homeostasis are frequent and seldom diagnosed in the Emergency Department. In both the adult and pediatric population, the causes of increased or decreased calcium are many, and the index of suspicion needs to be raised for these disorders. Selective ordering is warranted for patients with altered mental status, seizures, neuromuscular irritability, or in patients with diseases known to have abnormalities of calcium as a complicating factor. These include renal failure, multiple myeloma, metastatic cancer, granulomatous disease, and endocrinopathies.
