Coexisting Hemorrhagic Cerebral Cavernous Malformation and Developmental Venous Anomaly Resulting in Frontal Lobe Seizures: A Case Report.

Cerebral cavernous malformations (CCMs) are vascular malformations that can cause seizures and hemorrhages. Managing CCMs associated with developmental venous anomalies (DVAs) becomes more complex due to the risk of venous infarction and hemorrhage if the DVA is disrupted. This case report describes a 55-year-old man presenting with intractable seizures who was found to have a hemorrhagic CCM and an adjacent DVA in the frontal lobe. Surgical management involved complete removal of the CCM while preserving the DVA. Postoperatively, the patient had no further seizures, highlighting the importance of careful surgical planning and execution in managing coexisting CCMs and DVAs.
