Overview

Conus medullaris AVM is a very rare lesion. Only a few case reports have been described in the literature. The first cohort of 16 patients was described by Spetzler in April 2012. These AVMs are very complex, high‑flow lesions in eloquent area. The most frequent symptoms are paraparesis, sphincter disorders and pain. The lesion presents with bleeding in one third of patients. The authors describe a case of 30‑years old female with a half year history of slowly progressing symptoms. Her conus medullaris AVM was excised by microsurgery with a good result. This is the first case of a successfully treated conus medullaris AVM published in the Czech Republic. A literature review and our own experience suggest that the choice of treatment has to be individual. A combination of endovascular obliteration followed by microsurgical excision or microsurgical excision only is the most commonly used treatment modality. Good treatment results are possible in a large proportion of patients.

Key words:
arteriovenous malformation – conus medullaris – microsurgery – endovascular treatment
