[Value of ophthalmologic examination in early diagnosis of slow-growing intracranial tumors].

We report a case of clinically mute median fore brain tumor with meningeal origin and optic chiasm compression. The patient required the ophthalmological examination for "changing glasses".

Clinical controversy in orbitary cholesteatoma.

Cholesterol granulomas are tumor-like lesions very rarely encountered in the orbital, frontal sinus, and maxillary sinus sites but with higher frequency in the middle-ear and petrous apex. Theoretically, cholesterol granulomas develop as a reaction to localized hemorrhages, often occurring in bony sites with no blood and blood products drainage. We present 5 cases with exophthalmoses, namely, 3 cases with granuloma and 2 cases with cholesteatoma, all being characterized by the presence of cholesterol spikes at the histologic examination.

Vascular tumors in the orbit--capillary and cavernous hemangiomas.

Vascular tumors in the orbit result from new formation of vessels, proliferation of tissue components of the vessel wall, and hyperplasia of cellular elements ordinarily concerned with the genesis of vascular tissue. These vasculogenic lesions constitute the largest group of primary orbital tumors; we present the capillary hemangioma and the cavernous hemangioma.
