Pulmonary necrobiotic nodules are a rare extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD), which are often overlooked when diagnosing cavitary pulmonary nodules. We present this case to highlight the importance of a thorough differential diagnosis, which includes EIMs of ulcerative colitis (UC), in this case as necrobiotic nodules. Herein, we present a 25-year-old male patient with a history of poorly controlled UC who presented with fevers, left-sided abdominal pain, and bloody diarrhea. Imaging revealed cavitary pulmonary nodules without an infectious or malignant etiology. Lung biopsy and pathology confirmed a diagnosis consistent with necrobiotic nodules.
肺坏死结节是炎症性肠病（IBD）一种罕见的肠外表现（EIM），在诊断空洞性肺结节时常常被忽视。我们展示这个病例以强调全面鉴别诊断的重要性，其中包括溃疡性结肠炎（UC）的肠外表现，在本病例中即坏死结节。在此，我们报告一名25岁男性患者，有溃疡性结肠炎控制不佳病史，出现发热、左侧腹痛和血性腹泻。影像学检查发现有空洞性肺结节，无感染或恶性病因。肺活检及病理检查确诊为符合坏死结节的诊断。
