Cerebellar mutism after posterior cranial fossa surgery.
No full textMutism is a rare sequel of PCF tumor removal. Three patients aged 5 to 20 years old with mutism after posterior fossa surgery are presented. Suboccipital craniectomy was performed in all patients with grossly total removal of a medulloblastoma. The mutism that may occur after an operation for a PCF lesion has been explained in functional and/or organic terms. To date, 24 similar cases of mutism following cerebellar operations have been reported in the literature. We review the features of the syndrome in the light of the published cases and speculate on the underlying physiopathology. The absence of long tract or other brain stem signs, together with a presence of dysarthria during the recovery of speech, suggested a organic cerebellar cause of the mutism
Intracerebral schwannoma. Case report
No full textA case of intraparenchymal schwannoma is presented. A 61-year-old woman, with stigmata of von Recklinghausen's neurofibromatosis (NF-2), presented with a history of weakness of the right lower limb for 2 months. She was investigated by MR which showed a circular mass with a maximum diameter of 5 cm in the right parieto-occipital lobe. The tumor was removed in toto via a left parieto-occipital craniotomy. The patient was discharged two weeks after the operation and remains well now 2 years later. The clinical and neuroradiological findings of reported intraparenchymal schwannomas, including the case reported here, are discussed
Prognostic factors in intramedullary astrocytomas.
No full textThis report presents a retrospective prognostic study of 65 patients with intramedullary astrocytoma surgically treated between 1953 and 1990. Median survival and statistical survival at 5 years were assessed in relation to clinical, histological and therapeutic factors for each patient. Results showed that factors positively influencing the prognosis are low histological grade of the tumour and good pre- and post-operative general conditions. Among the grade II astrocytomas, the fibrillary and protoplasmatic types presented longer survival times regardless of the type of removal performed. In anaplastic astrocytomas the simultaneous presence of certain morphological features indicative of higher malignancy negatively influenced survival. The degree of resection did not influence average survival within each histological grade
Spontaneous movement of metallic foreign bodies. Case report.
No full textWe report a case of missile injury to the brain with an unusual complication. The bullet migrated by its mere weight to a distant location through the brain parenchyma after initially lodged in a superficial site. Movement of the bullet was first detected on CT scan and the significance and treatment of this finding is emphasized
Ossifying fibroma of the skull: clinical and therapeutic study.
No full textAIMS AND BACKGROUND:
Ossifying fibroma is a tumor with benign course that rarely affects the cranial bones.
METHODS:
The authors report 5 cases of ossifying fibroma of the skull and analyze the clinical course and treatment of this lesion.
RESULTS:
3 patients were females and 2 males. The mean clinical history was 3.2 years. 4 patients underwent total removal and 1 partial. At mean follow-up of 19 years, all patients who underwent total removal showed improvement of neurological deficit, whereas the patient who underwent partial removal had clinical regrowth.
CONCLUSION:
The authors conclude that total removal of fibroma should be extended to normal bone and in cases in which total removal is not possible the residue should be checked for regrowth by serial MRI
Radiation-induced sarcoma of the skull: report of two cases.
No full textThe authors describe two cases of sarcomas of the skull following cranial irradiation in patients treated for other neoplasms, acute lymphatic leukemia, and astrocytoma, respectively. The patients (one man and one woman: mean age 24.5 years) developed sarcomas within the irradiated field after a mean latency period of 11.5 years. Histologically, the tumor proved to be a fibrosarcoma. Despite aggressive surgery and other therapy, the survival of the patients was short (10 and 8 months, respectively). The pathological and clinical aspects of this unusual complication are analyzed with reference to 41 cases taken from the world literature
Bifid median nerve: report of two cases
Full text linkThe median nerve divides into its terminal branches at or proximal to the distal edge of the flexor retinaculum. An anatomy of the median nerve within the carpal tunnel is reported in two separate cases. Emphasis has been given to the value of direct vision when incising the flexor retinaculum in order to avoid injure of the median nerve
