[Clinical picture and diagnosis of leptomeningeal sarcomatosis].

The study is based on the analysis of 10 cases of sarcomatosis of the brain and spinal pia mater. A progressive development of the disease, cachaxia, the existence of focal symptoms, radicle pain, xantochromia in the CSF, protein-cell dissociation and some other signs are characteristic of primary sarcomatosis of the pia mater. On the basis of clinical symptoms and CSF changes it is possible vitaly to perform a differential diagnosis with chronic infectious diseases and especially with tubercular meningitis and polyradiculomyelitis. Pathomorphological studies revealed tissue infiltration of the surrounding intracerebral vessels by tumors cells without proliferation into the dura mater and radicles of the spinal cord.
