BACKGROUND
Collision tumor is a very rare case of cerebral lesion. Approximately 50 reports of intracranial collision tumors were described in the literature. We present a case of supratentorial dural-based convexity collision tumor radiologically mimicking cavernous malformation and composed of cavernous malformation and meningioma.
CASE PRESENTATION
The case presents a 63-year-old female having MR findings such as hemorraged supratentorial dural-based mass with "popcorn" signs and hemosiderin deposits. The patient underwent craniotomy and evacuation of the subdural hematoma with resection of the tumor mass. Histologically the lesion had signs of a cavernoma and meningioma. MRI in a year after surgery did not reveale residual tumor mass or recurrence.
CONCLUSIONS
Collision tumor is a very rare case. Preoperative diagnosis of a dural lesion is difficult and challenging. A neuroradiological differential diagnosis of similar cases needs focused attention.
背景
碰撞瘤是一种非常罕见的脑病变病例。文献中大约描述了50例颅内碰撞瘤。我们报告一例幕上硬脑膜凸面碰撞瘤，影像学上酷似海绵状畸形，由海绵状畸形和脑膜瘤组成。
病例介绍
该病例为一名63岁女性，磁共振成像（MR）表现为幕上硬脑膜下出血性肿块，伴有“爆米花”征和含铁血黄素沉积。患者接受了开颅手术，清除了硬膜下血肿并切除了肿瘤肿块。组织学检查显示病变有海绵状血管瘤和脑膜瘤的特征。术后一年的MRI检查未发现残留肿瘤肿块或复发。
结论
碰撞瘤是一种非常罕见的病例。术前诊断硬脑膜病变困难且具有挑战性。对于类似病例的神经放射学鉴别诊断需要重点关注。
