Clinical and radiological evaluation of a spontaneously occluded intracranial arteriovenous malformation [Spontan olarak ti{dotless}kanan bir i̇ntrakranyal arteriovenöz malformasyonun klinik ve radyolojik olarak deǧerlendirilmesi]

Spontaneous obliteration of brain avms is extremely rare estimated less than 1%. we report the case of a 37 year-old female with a history of seizures treated with anticonvulsives,who sought medical attention because of recurrence of her symptoms. the mri findings were attributed to a patent avm located at the left occipital lobe. further radiological exams (angiography,ct,plain radiograms) revealed a totally calcified lesion probably representing an occluded avm. the prompt diagnosis of spontaneous obliteration of a brain avm requires a high index of suspicion and multidisciplinary radiologic evaluation with mri,angiography,ct and plain radiograms.
