The authors report a symptomatic congenitally anomalous ectatic vertebral artery not passing through the transverse foramen of the atlas (C-1), but instead piercing the dura mater below the posterior arch of the C-1 in the atlantoaxial (C1-2) interlaminar space. This occurrence is exceptionally rare, but in this case it was uniquely associated with(More)
Glioblastoma multiforme (GM) of the cerebellum is a rare tumour. A variant of GM, a multifocal giant cell glioblastoma, initially presenting in the cerebellum, has not previously been reported. A giant cell glioblastoma occurring in a 46-year-old man who presented initially with a cerebellar tumour is described. One month after excision of the tumour, the(More)
A retrospective study of 17 cases of primary cerebral gliosarcoma is presented. These uncommon highly aggressive intracranial neoplasms were seen at the Royal Preston Hospital, between 1973 and 1992. The patients' ages ranged from 21 to 73 years (mean 52), nine were males and eight were females. They presented with signs and symptoms of a rapidly expanding(More)
Primary cranial vault non-Hodgkin's lymphomas are rare and only four such cases are described in the literature. A 65-year-old woman presented with focal neurological deficits and a subcutaneous scalp lump. Computed tomography (CT) scan showed a left parietal cranial vault lesion with soft tissue scalp swelling and underlying intracranial extra axial mass(More)
Ossification of the ligamenta flava (OLF) and posterior longitudinal ligament (OPLL) of the spine causing spinal cord compression is described mainly in Japanese patients and is often termed as 'Japanese disease'. We are reporting a case of OLF of the thoracic spine seen in a male Caucasian who presented with an intractable intercostal pain. This is the(More)
Intraparenchymatous schwannomas of the central nervous system are rare. In decreasing order of frequency they are found in the spinal cord, cerebral hemispheres, brainstem and cerebellum. So far, only six such tumours have been reported in the cerebellum. A male predominance and early onset of symptoms are salient features. A case of a 73-year-old Caucasian(More)
Two rare cases of intracranial meningeal melanocytoma are reported with clinical, radiologic, and pathologic findings. In one of these the diagnosis was established by ultrastructural studies that showed premelanosomes and melanosomes in nonarachnoid-derived tumor cells. The other case was diagnosed retrospectively after a very long survival and is still(More)
