Abstract Details

Developmental Venous Anomaly Inside a Glioblastoma

By and large, developmental venous anomalies (DVA) are incidentally found asymptomatic vascular lesions. They serve as channels for normal brain parenchyma; thus, resection of the lesion is usually not performed.

We present a case of a 34-year old gentleman presented with a 3-week history of worsening headache and diplopia. Cranial magnetic resonance imaging showed a complex heterogeneously enhancing left frontal intraxial mass. A prominent transmedullary vein consistent with a DVA was also seen in the center of the mass. A catheter angiogram confirmed the finding of a developmental venous anomaly, with the lesion appearing in the mid-to-late arterial phase. More importantly, the study demonstrated that the peritumoral brain parenchyma drained through the superior sagittal sinus rather than the DVA. Five days after admission he underwent a left frontal craniotomy for resection of the tumor. Histopathology revealed findings of a glioblastoma multiforme. Post-operative imaging demonstrated the adequate resection of both tumor and DVA.

Outright resection of a DVA may result in catastrophic compromise of venous drainage. As such, the decision to perform extensive surgical resection on our case was only made after catheter angiography demonstrated normal brain parenchyma did not drain into the DVA.  DVAs also occur with other vascular malformations such as cavernomas but the association between DVAs and intracranial tumors is much less described. Though theories on developmental insults occurring in-utero and genetic predisposition have been put forward, the link between the pathophysiologic processes resulting in both a vascular malformation and malignant tumor remains uncertain. The case report highlights the importance of meticulous pre-operative vascular imaging and sheds light on the first reported case of a DVA inside an intracranial neoplasm.
