[Significance of changesin the topography of the superior cerebellar artery in the angiographic diagnosis of tumors of the posterior cranial fossa (II)].

Typical shifts of the superior cerebellar artery and its segments were studied in 67 vertebral angiogrammes showing 33 acoustic neurinomas, 7 meningiomas of the cerebellopontile angle, 13 cerebellar hemispheres tumours, 10 pontile tumours and 4 meningiomas of the free margin of the tentorium. The rationale of accounting for the angiographic symptom complexes typical for acoustic neurinomas with varying directions of growth were singled out.
