Abstract
BACKGROUND: Cavernous venous malformation is an uncommon entity that occurs in around 0.5% of the general population. Cerebellar cavernous venous malformation accounts for 1.2-11.8% of intracranial cavernous venous malformation cases. Patients are commonly asymptomatic until a hemorrhage occurs. In approximately 20% of the cases, cavernous venous malformation and developmental venous anomalies occur together, called mixed vascular malformation. Our case report reveals the imaging features of the mixed vascular malformation and highlights the appropriate imaging modality and sequence to detect the abnormalities. CASE PRESENTATION: We report the case of a 15-year-old Malay male, a healthy young male who presented with dizziness, vomiting, and mild headache for 1 month. Computed tomography brain imaging at presentation revealed cerebellar hemorrhage with multiple cavernous venous malformation and coexisting developmental venous anomalies, which was then confirmed by magnetic resonance imaging. The patient was started on dexamethasone 4 mg four times a day, observed in the ward, and discharged well without neurological sequelae. CONCLUSION: A cavernous malformation with concurrent developmental venous anomalies requires accurate diagnosis. Our case report contributes to the literature on the imaging diagnosis of this disease, which is beneficial for current and future reference.
