title: [A case of colloid cyst of the third ventricle (author's transl)].
abstract: The authors report a case of colloid cyst of the third ventricle diagnosed preoperatively through CT scan, pneumoencephalography and carotid angiography. The patient was a twenty-six year old housewife with a history of two repeated episodic headaches followed by gait disturbance, vomiting and cold sweating. At operation, the colloid cyst which completely occluded the right foramen of Monro, was reached by anterior transcallosal approach and was partially removed with subsequent cure of her symptoms. The cyst fluid contained cholesterin crystals, cholesterol, protein (12.8 g/dl), and sugar (16 mg/dl). Histologically, the cyst wall consisted of a single layered cuboidal or columnar epithelium with many cilias internally and loose connective tissue rich in vascluar channels externally. Cytoplasm and cellular surface was partly positive at mucicarmine, PAS and alusian blue staining. The fact would confirm that there is mucin secreting function among the epithelial cells of the cyst.
