Mycetoma is a chronic granulomatous disease that is more common in tropical regions with predominant involvement of foot. Spinal mycetoma presenting as lumbar canal stenosis is extremely rare. We hereby present a case of fungal eumycetoma of vertebral column in a 42-year-old male who presented with chronic progressive low back pain and features of lumbar canal stenosis without any skin swelling or discharging sinuses. The "dot-in-circle" sign, a highly specific magnetic resonance imaging (MRI) and ultrasonography (USG) sign of mycetoma has been described in the literature as a pathognomonic feature of mycetoma involving the musculoskeletal system. We describe the importance of characteristic imaging features with dot in circle sign in the diagnosis of eumycetoma of lumbar spine.
足菌肿是一种慢性肉芽肿性疾病，在热带地区更为常见，主要累及足部。表现为腰椎管狭窄的脊柱足菌肿极为罕见。我们在此报告一例42岁男性脊柱真菌性足菌肿病例，该患者表现为慢性进行性下腰痛及腰椎管狭窄特征，无任何皮肤肿胀或窦道流脓。“圈内点”征是足菌肿一种高度特异性的磁共振成像（MRI）和超声检查（USG）征象，在文献中被描述为累及肌肉骨骼系统的足菌肿的特征性表现。我们描述了具有“圈内点”征的特征性影像学表现对诊断腰椎真菌性足菌肿的重要性。
