Radiographic demonstration of calcification within spinal canal tumors is rare [1] . The most common lesion of this type showing calcification is a meningioma. Other lesions showing calcification include neurofibromas, hemangioblastomas, neuroblastomas, ganglioneuromas, and herniated thoracic disks. Very rarely is calcification seen within neurilemomas [2, 3] , and, if present, it may be noted ...

Nuclei of human neurilemoma cells exhibit deep and extensive invaginations of part of their surface. Such invaginations contain cytoplasmic matter. However, in areas of the nucleoplasm distant from the invaginations, small membrane-bound bodies, some of which contain a "nucleoid," occur either singly or grouped together and enclosed within a large membrane body. These small bodies are not consi...

The study presented a case of a patient with a neurilemoma of the median nerve. It presented as a six centemeters tumor, at the level of the proximal one third of the arm with only mild paraesthesias within first to third ray of the hand. MRI showed the relationship of the tumor and the median nerve, and allowed for the preliminary diagnose of a benign peripheral neural sheath tumor (neurilemom...
