Abstract
BACKGROUND: Madelung's disease (MD) is a rare disorder of fat metabolism, which is usually associated with diabetes, hyperuricemia, liver disease, nevertheless there is no report of a patient with MD and pulmonary aspergillosis (PA). This article aimed to enhance the awareness of this two diseases and discuss the possible mechanism of the combination of them preliminarily. CASE PRESENTATION: In this case, we described a 56-year-old male patient with cough, expectoration and dyspnea. His neck has a very peculiar appearance. Chest enhanced CT scan showed there were multiple nodules in both lungs, some of which had cavities and the mediastinal lymph nodes were swollen. Ultrasound scan of the neck showed diffuse hyperplasia of subcutaneous fat in neck and bilateral supraclavicular fossa. Fortunately, after performing pulmonary wedge resection aimed at pathological examination and giving relevant treatments, this patient was finally diagnosed as MD with PA, and his symptoms were significantly relieved. CONCLUSIONS: MD is rare, the phenomenon that MD combined with PA is rarer. Immune disorder may be the possible mechanism.
