Abstract In a retrospective study of 72 patients with developmental venous anomalies (DVA) diagnosed by MRI and/or angiography, 33 associated lesions were found in 32 patients (44%). Study of the clinical files allowed classification of the patient population into three groups. In group 1 (11 patients: 34%) the symptoms were attributed with certainty to the associated lesions (1 brain infarction, 2 multiple sclerosis patients, 1 case of meningitis, and 7 patients with tumors). In group 2 (9 patients: 28%) the symptoms were probably caused by the associated lesion and not by the associated DVA (1 contusion, 1 Sturge-Weber angiomatosis, and 7 hemorrhagic DVA). In group 3 (12 patients: 38%) the symptoms were nonspecific (10 cavernous angiomas, 1 varix with sinus pericranii, and 1 ectasia of the middle cerebral artery. These findings sustain the theory that DVA is a congenital anomaly of the venous drainage of the brain, without pathological significance, and must be considered as an incidental finding.
