Situs inversus totalis with a mature teratoma of the posterior mediastinum: A case report

Situs inversus totalis is an unusual disease with a low incidence. The co-existence of situs inversus totalis with a teratoma is extremely rare. To the best of our knowledge, there is no data on the association between situs inversus totalis and teratoma in the literature. The present study therefore describes the first such case in a 23-year-old female. The patient presented with intermittent chest tightness, which had lasted for similar to 3 years. Following radiological examination, the patient was diagnosed with situs inversus totalis and a mature teratoma in the posterior mediastinum. Surgical resection was performed to remove the teratoma and the patient subsequently made a full recovery. Follow-up X-ray and computed tomography examinations were performed 6 months after surgery, which revealed no disease recurrence.
