Combined forms of meningitis: Mixed infection of the meninges by the tubercle bacillus and meningococcus.

Fibrosarcoma of the meninges

Meningeal fibrosarcomas are rare tumors. Only 41 cases have been reported in the literature to date. Primary central nervous system fibrosarcomas are very aggressive neoplasms and have a poor prognosis. Hence they need to be correctly diagnosed. This is a case of a 13-year old boy with intracranial space occupying lesion. The mass was completely removed and histological examination was characte...

Meninges in cancer imaging

Primary malignant tumours arising from the meninges are distinctly uncommon, and when they occur, they are usually sarcomas. In contrast, metastatic meningeal involvement is increasingly seen as advances in cancer therapy have changed the natural history of malignant disease and prolonged the life span of cancer patients. The meninges can either be infiltrated by contiguous extension of primary...

The Anatomy of the Meninges.

A note may be added here as to certain findings not usually recorded in "official" descriptions of examinations of the cerebro-spinal fluid. In the centrifugalised deposits of lumbarpuncture specimens, I have not infrequently encountered squamous cells from the skin-surface, together with their accompanying staphylococci, etc., and occasionally even a little cylindrical fragment of skin punched...

Meninges, Ventricular System, and CSF

Coverings of the brain As introduced in the 2nd lecture, the brain is covered by three layers namely: dura mater, arachnoid, pia matter. The dura mater is of significance due to the venous sinuses and is the toughest layer/s (two layers in fact) – and its upper layer is directly attached to the periosteum. The blood vessels travel between the arachnoid and pia mater. The arachnoid and pia mater...
