A chronic expanding hematoma is a hematoma with long term, continuous growth. A 69-year-old male presented with an extra-thoracic chronic expanding hematoma 45 years after thoracoplasty. Six months prior to his visit with us, he had noticed a slight swelling on his back. Three months before his visit with us, the size of the swollen area gradually increased after bowling. Magnetic resonance imaging (MRI) showed an extra-thoracic lesion measuring 120 mm in diameter. Heterogeneous signal intensity on T1- and T2-weighted images inside the lesion was reflected as hematoma of various ages. The hematoma was successfully resected after preoperative embolization. Chronic expanding hematoma can be a delayed complication after thoracoplasty.
慢性扩展性血肿是一种长期持续生长的血肿。一名69岁男性在胸廓成形术后45年出现胸外慢性扩展性血肿。在他来我院就诊前6个月,他注意到背部有轻微肿胀。在他来我院就诊前3个月,保龄球运动后肿胀区域的大小逐渐增大。磁共振成像(MRI)显示一个直径为120 mm的胸外病变。病变内T1加权和T2加权图像上的信号强度不均匀,提示为不同时期的血肿。术前栓塞后成功切除了血肿。慢性扩展性血肿可能是胸廓成形术后的一种延迟并发症。
