Epithelioid hemangioendotheliomas (EHE) is an extremely rare tumor that can arise not only intracranially but also systemically. Its radiological characteristics and the mechanism underlying the multiple organ involvement in EHE are poorly understood.
A 24-year-old woman with a 7-month history of coughing and blood-stained sputum complained of visual disturbance in the right eye that had persisted for 1-month. Magnetic resonance (MR) imaging revealed multiple intraparenchymal masses with low-intensity on MR susceptibility-weighted images with minimal enhancement with gadolinium. Systemic computed tomography revealed multiple nodules in both lungs and the liver. Because her neurological status rapidly deteriorated, brain biopsy of the right frontal mass was performed. The pathological diagnosis was EHE. Over the following 3 months, the patient gradually developed disturbance of consciousness. She died at 4 months after admission because of significant intracranial hypertension.
Although intracranial EHEs are extremely rare, they should be included in the differential diagnoses of multiple small-sized masses with low-intensity on MR susceptibility-weighted images. We also emphasize that the systemic involvement of this tumor was more compatible with multicentric development than metastasis.
上皮样血管内皮瘤(EHE)是一种极为罕见的肿瘤,不仅可发生于颅内,也可发生于全身。其影像学特征以及EHE累及多个器官的潜在机制尚不清楚。
一名24岁女性,有7个月咳嗽和痰中带血病史,主诉右眼视力障碍已持续1个月。磁共振(MR)成像显示脑实质内多个肿块,在MR磁敏感加权图像上呈低信号,钆增强极少。全身计算机断层扫描显示双肺和肝脏有多个结节。由于其神经状态迅速恶化,对右侧额叶肿块进行了脑活检。病理诊断为EHE。在接下来的3个月里,患者逐渐出现意识障碍。她在入院4个月后因严重颅内高压死亡。
尽管颅内EHE极为罕见,但在MR磁敏感加权图像上呈低信号的多个小肿块的鉴别诊断中应考虑到它。我们还强调,该肿瘤的全身累及更符合多中心发展而非转移。
