Schwannomatosis is a rare disorder, still not quite well defined, seldom described in the literature. In this paper we report the case of male. Patient, 52 years old, who in the last 30 years developed five subcutaneous tumors within his limbs peripheral nerves, which histologically proved to be schwannomas. A brain computed tomography showed a partially calcified tumor in the left temporal lobe which most likely was a meningioma. A thorough clinical examination was unable to find signs of type I or type II neurofibromatosis. The present condition, probably a form of phacomatosis, has to be distinguished from neurofibromatosis and is considered as an independent clinical entity whose origin still awaits further detailed investigations.
Using transillumination and a sensitive cadmium sulfide light meter, 145 newborns were screened for the presence of intracranial hemorrhage. Intracranial hemorrhage (ICH) was suspected when the light meter could not detect any light passing through the anterior fontanel when the light beam was directed through the frontal eminence. ICH was confirmed by cranial computed tomography or postmortem examination in all 17 infants not transmitting light. Spectrophotometry was performed on samples of cerebrospinal fluid (CSF) to demonstrate the mechanism through which blood in the CSF blocks light transmission.
