The presentation of recurrent pneumonia, particularly in the same lobe, should raise suspicion for possible neuroendocrine tumors of the lung within that respective lobe. Commonly, these types of tumors will have a gastrointestinal origin with a larger incidence of carcinoid syndrome, but they may also originate in the pancreas or lungs. This case illustrates the potential for a masked lung tumor in an otherwise young and healthy 31-year-old patient, with a short history of tobacco dependence and unremarkable family history, who presents with recurrent pneumonia and dyspnea. Although rare in itself, this case was even more unique due to the partial calcification of the neuroendocrine tumor mass along with causing a collapse in the entire right middle lobe.
复发性肺炎的出现,尤其是在同一肺叶,应引起对该肺叶内可能存在肺神经内分泌肿瘤的怀疑。通常,这些类型的肿瘤起源于胃肠道,类癌综合征的发生率较高,但也可能起源于胰腺或肺部。本病例说明了一名31岁年轻健康患者,有短暂的烟草依赖史且家族史无异常,却出现复发性肺炎和呼吸困难,可能存在隐匿性肺肿瘤。虽然这种情况本身罕见,但该病例更独特之处在于神经内分泌肿瘤肿块部分钙化,并导致整个右中叶肺不张。
