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.
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.
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.
海绵状静脉畸形是一种罕见的疾病，在普通人群中发病率约为 0.5%。小脑海绵状静脉畸形占颅内海绵状静脉畸形的 1.2-11.8%。患者通常无明显症状，直到发生出血。大约 20%的情况下，海绵状静脉畸形和发育性静脉异常同时发生，称为混合性血管畸形。本病例报告揭示了混合性血管畸形的影像学特征，并强调了适当的成像方式和序列来检测异常。
我们报告了一例 15 岁马来男性病例，该患者为健康年轻男性，因头晕、呕吐和轻度头痛 1 个月就诊。就诊时的颅脑 CT 成像显示小脑出血伴多发性海绵状静脉畸形和并存的发育性静脉异常，随后通过磁共振成像得到证实。患者开始接受每日 4 毫克地塞米松，4 次/天，在病房观察，出院时无神经后遗症。
并发发育性静脉异常的海绵状静脉畸形需要准确诊断。本病例报告有助于丰富该病的影像学诊断文献，为当前和未来提供参考。
