Hydrocephalus and Intraspinal Tumor
The association of hydrocephalus with mass lesions affecting the spinal cord is a rare but well documented phenomena. A search of the literature disclosed 67 reported cases with a wide variety of pathological diagnosis ranging from the benign or malignant tumors to non-neoplastic conditions such as disc herniation, granuloma, and vascular malformation. Two new cases are reported; these elderly females presented with a demential picture in association with hydrocephalus, verified by Computed Tomography of the head and progressive motor difficulties of the lower extremities. The massively elevated protein in the lumbar cerebrospinal fluid led to myelography and diagnosis of a near complete block at the lower thoracic area. In case number one the cerebrospinal fluid sampled above the lesion was only moderately elevated. Complete tumor resection of a T-12 meningioma in case one and subtotal excision of a T-12 Schwannoma in case two, rein significant improvement of their mental faculties. Resolution of the hydrocephalus was documented in follow up Computed Tomography of the head.
