Chronic expanding organizing hematoma (CEH) occasionally mimics a soft tissue tumor on MRI, which becomes more problematic in patients with a history of surgical resection for musculoskeletal malignancy. Herein, we present a case of CEH which we were able to differentiate from recurrent tumor through MRI follow-up, including diffusion-weighted imaging (DWI) and dynamic contrast enhanced (DCE) imaging. A 66-year-old male visited our institution under suspicion of recurrent leiomyosarcoma of the thigh, 19 months after surgery and radiation therapy. Due to inconclusive results, three US-guided biopsies and 6 MRI examinations were performed over 2 years. In the end, we could diagnose a CEH using conventional and functional MRI techniques, and it was histopathologically confirmed after surgical resection. A CEH may occur remotely after an initiating event, and it may persist and expand over several years. Functional MR sequences, in addition to conventional sequences, are helpful in differentiating CEH from malignant neoplasms.

흉강 내에 발생하는 만성 팽창성 혈종은 매우 드문 질환이다. 저자들은 20년 전 결핵성 늑막염을 앓고 난 뒤 반복적인 객혈로 3개월 전부터 외래 추적 관찰하던 노인에서 갑작스런 대량 객혈과 함께 이전 방사선 소견에서 병변을 가득 채웠던 물질이 새롭게 발생한 기관지 흉막루를 통해 소실되어 공기 액체층이 새롭게 형성된 일련의 변화를 통해, 내부 성분이 혈액임을 확인하여, 병변이 만성 팽창성 혈종임을 진단하였기에 문헌 고찰과 함께 보고 하는 바이다.

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease that behaves as a slowly expanding lesion with a gradual onset. It is well established that CEIH is associated with arteriovenous malformations; however, CEIH associated with cavernous malformation (CM) is extremely rare. We herein report a case of CEIH associated with CM, and discuss its pathogenesis. A 12-year-old female was admitted to our hospital because of a one week history of progressive headache and nausea. Brain computed tomography scan and magnetic resonance imaging showed an intracerebral hematoma surrounded by edema in the right frontal lobe. One week later, her headache and nausea worsened, and a brain computed tomography scan revealed the enlargement of hematoma. A right frontal craniotomy was performed. The capsule, mass, and hematoma were totally removed. Histological examination confirmed the diagnosis of CEIH associated with CM. Immunohistochemical analysis revealed increased expression of vascular endothelial growth factor (VEGF) and the VEGF receptor-1 in the endothelium and fibroblasts. Our findings suggest that the activated VEGF pathway might have positively contributed to development of CEIH in the present patient.

저자들은 대량 객혈로 발현한 흉곽 내 만성 팽창성 혈종 1예를 보고한다. 이 증례는 이전의 증례와 달리 결핵성늑막염이나 흉부 수술, 외상의 과거력 없이 자연 발생한 증례라는 점에서 의의가 있다. 또한 무증상, 호흡곤란 등으로 발현했던 대부분의 증례와는 달리 드물게 대량객혈로 발현하였으며, 이러한 대량객혈이 기관지흉막루를 동반하여 발생하여 기관지동맥 색전술과 수술로 치료되었다는 점에서 특징적이다. 증례보고와 함께 문헌고찰을 통해 과거 보고된 흉곽 내 만성 팽창성 혈종의 임상양상에 대해 표로 정리하였다.
