Intramuscular cavernous venous malformation of extraocular muscles. Fractionated stereotactic radiotherapy as a therapeutic alternative. / Malformación venosa cavernosa en musculatura extrínseca ocular. Radioterapia estereotáctica fraccionada como alternativa terapéutica.

Intramuscular cavernous venous malformations affecting extraocular muscles are extremely uncommon. Due to their location, complete resection could be difficult. A clinical case is presented of an inferior rectus muscle orbital cavernous malformation treated with fractionated stereotactic radiotherapy after post-surgical excision recurrence. The malformation responded to radiotherapy with a reduction in size and symptoms. Fractionated stereotactic radiotherapy is an alternative and effective treatment for cavernous venous malformations that are surgically challenging due to their radiotherapy sensitivity.
