The occurrence of lipoma in the thoracic cavity is relatively rare, and it is clinically difficult to distinguish it from liposarcoma. We report a case of intrathoracic lipoma that was pathologically diagnosed and differentiated from liposarcoma after minimally invasive thoracoscopic tumour resection. A 35‐year‐old male patient without any symptoms was referred to our hospital due to an abnormal shadow on chest x‐ray. Computed tomography showed a low‐attenuated round‐shaped mass of 3.6 cm × 2.3 cm in diameter in the left chest wall. On magnetic resonance imaging, the mass was displayed as a high, high and low signal mass on T1‐weighted imaging (WI), T2WI and T2WI with fat suppression, respectively. We suspected a chest wall‐type lipoma, but because it appeared in a relatively short period of time and we thought it could be liposarcoma, we performed minimally invasive thoracoscopic surgery for diagnosis and treatment. The tumour was a stalked tumour with a capsule, contiguous to the wall pleura with only a single cord‐like structure. The majority of the tumour was found free in the pleural cavity. The tumour was diagnosed as a lipoma by histopathological examination.
