Sinusoidal hemangioma is a rare type of cavernous hemangioma with different clinico-pathological aspects. They are usually localized in the extremities with interest in the subcutaneous layer. The new imaging techniques play an important role in diagnosis, evaluation and follow-up of these types of tumors. We describe the case of a 21-year-old patient, four times operated for a recurrent soft tissue tumor, located intramuscularly in the distal third of the upper limb. Plain X-ray and computer tomography (CT) showed a nonspecific mass with calcification. The MRI (magnetic resonance imaging) exam demonstrated a lobulated heterogeneous signal tumor mass in the biceps brachial muscles, with high signal intensity on T2 weighted images and intermediate signal on T1 weighted images. MRI accurately assessed the extent of the tumor and evaluated the recurrence. MRI imagings combined with contrast-enhanced sequences were used to classify the lesions in low flow vascular disorders. CT angiography with multiplanar reconstructions (MPR), maximum intensity projections (MIP) and volume-rendered reconstructions (VR) was useful in confirming the venous origin of the tumor.
窦性血管瘤是一种罕见的海绵状血管瘤，具有不同的临床病理特征。它们通常位于四肢，多见于皮下层。新的成像技术在这些类型肿瘤的诊断、评估和随访中发挥着重要作用。我们描述了一名21岁患者的病例，该患者因复发性软组织肿瘤接受了四次手术，肿瘤位于上肢远端三分之一的肌肉内。平片和计算机断层扫描（CT）显示有钙化的非特异性肿块。磁共振成像（MRI）检查显示肱二头肌中有一个分叶状的异质性信号肿瘤肿块，在T2加权图像上呈高信号强度，在T1加权图像上呈中等信号。MRI准确评估了肿瘤的范围并评估了复发情况。结合对比增强序列的MRI成像用于将病变分类为低血流血管疾病。具有多平面重建（MPR）、最大强度投影（MIP）和容积再现重建（VR）的CT血管造影有助于确认肿瘤的静脉起源。
