Lipoma arborescens (LA) is a rare, benign articular lesion that is most commonly found within the suprapatellar recess of the knee. An extremely rare case of LA involving unilateral bicipitoradial bursa is described in this study. A 58-year-old male presented with a superficial soft mass on the volar aspect of the left forearm. The magnetic resonance imaging (MRI) examination demonstrated a lobulated complex mass containing multiple frond-like fatty nodules, along the distal biceps tendon in the bicipitoradial bursa. Ultrasound-guided biopsy of the lesion confirmed the diagnosis of LA and patient was scheduled for surgical excision. Recognizing the characteristic imaging of LA, particularly on MRI, is essential for accurate pre-procedural diagnosis.
树枝状脂肪瘤（LA）是一种罕见的良性关节病变，最常见于膝关节的髌上隐窝。本研究描述了1例极其罕见的累及单侧肱桡滑囊的LA病例。一名58岁男性，左前臂掌侧出现一个浅表软组织肿块。磁共振成像（MRI）检查显示，在肱桡滑囊内，沿着肱二头肌远端肌腱有一个分叶状的复杂肿块，包含多个叶状脂肪结节。对该病变进行超声引导下活检，确诊为LA，患者计划接受手术切除。认识LA的特征性影像学表现，尤其是在MRI上的表现，对于术前准确诊断至关重要。
