The dimensions and the unilateral, flattened shape of the longitudinally sectioned structures clearly identify these as eggs of Enterobius vermicularis (thin arrows). The thick arrow indicates an elongated structure protruding from 1 of the eggs; this represents a hatching larva trapped in the inflammatory mass (original magnification, ϫ40). Diagn...

Enterobius vermicularis is a nematod of large intestine in man. Extra intestinal localization of this parasite is rare. A 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. In laboratory examination of cerebrospinal fluid (C.S.F), the appearance was red, Albu-min level was high and the glucose showed normal value. Haematoxylin and Eosin stained slides pr...
