Denervation pseudohypertrophy is an uncommon cause of limb swelling, which may be overlooked. It is an important diagnosis to arrive at, as it instructs the search for an underlying cause which may itself require intervention. We present the case of a 32-year-old male rugby player with a 2-year history of left calf swelling and intermittent pain and tightness. He described a previous history of 2 left sided lumbar micro-discectomy surgeries. There was no tenderness or sensory deficit on examination. MRI of the left calf revealed muscular enlargement, with fat interspersed between the muscle fibers, in keeping with pseudohypertrophy. This has a number of causes, in this cause attributed to lumbar radiculopathy. This case highlights a rare but important cause of limb swelling which should be considered in the workup of a unilateral swollen limb.
去神经支配性假性肥大是肢体肿胀的一种罕见原因，可能会被忽视。这是一个需要做出的重要诊断，因为它指导寻找可能本身需要干预的潜在病因。我们报告一例32岁男性橄榄球运动员，有2年左小腿肿胀、间歇性疼痛和紧绷感的病史。他描述曾有过2次左侧腰椎显微椎间盘切除术史。检查时无压痛或感觉障碍。左小腿MRI显示肌肉增大，肌纤维间有脂肪夹杂，符合假性肥大表现。其有多种病因，本例病因归因于腰椎神经根病。该病例突出了肢体肿胀的一种罕见但重要的原因，在单侧肢体肿胀的检查中应予以考虑。
