The association between cerebral developmental venous anomaly and concomitant cavernous malformation: an observational study using magnetic resonance imaging. Developmental venous anomalies (DVA): the so-called venous angioma. Yet the morbidity of DVA is mostly related to the associated lesions rather than to the DVAs. The role of DVAs in the venous drainage of normal brain parenchyma shouldn’t be underestimated since surgical resection can lead to severe complications such as venous infarction and hemorrhage. In children there have been various reports of DVAs with associated cavernoma, lymphatic or venolymphatic malformations, focal cortical dysplasia’s, epilepsy, brain tumors, hydrocephalus due to aqueduct obstruction or unilateral sensorineural hearing loss. They can be associated with other vascular malformations predominantly cavernomas but many other associated lesions and parenchymal changes have been described in the adult and pediatric population.
A DVA is composed of linear branching veins (the “caput medusa”) which drain into a single larger collecting vein and eventually into the superficial or deep venous system. They are typically an incidental finding on CT or MRI during diagnostic evaluation for a wide range of symptoms which are rarely attributed to the DVA itself. Postoperative imaging demonstrated the adequate resection of both tumor and DVA.DVAs are the most common type of intracranial vascular malformation and are considered low flow conditions. He was discharged within 2 days after surgery. A histopathologic examination revealed findings of a glioblastoma multiforme ( Figure 2A and B). Five days after admission, the patient underwent a left frontal craniotomy for resection of the tumor. More importantly, the study demonstrated that the peritumoral brain parenchyma drained through the superior sagittal sinus rather than the DVA. A catheter angiogram confirmed the finding of a DVA, with the lesion appearing in the mid to late arterial phase ( Figure 1B Video). A prominent transmedullary vein consistent with the developmental venous anomaly (DVA) was also seen in the center of the mass ( Figure 1A). Cranial magnetic resonance imaging showed a complex left frontal intraxial mass with heterogeneous enhancements. The results of a metastatic workup with computed tomography were negative. The rest of his neurologic examination had unremarkable results, except for mild optic-disc swelling. On admission, he was alert, oriented, and able to follow commands. A cranial computed tomography scan with findings consistent with a left frontal tumor prompted a referral to our institution. A 34-year-old man presented with a 3-week history of worsening headache and diplopia.
