We describe a 9-year-old child with a history of trichoptysis caused by intrapulmonary teratoma and we present the CT and MRI findings of the teratoma. A heterogeneous mass containing cystic and solid elements was detected on both CT and MRI scans. Histopathological examination confirmed the diagnosis of teratoma. Teratomas arising from lung parenchyma, as in this case, are extremely rare in childhood. In the thoracic region, the most common localization of teratomas is the anterior mediastinal compartment. We also discuss the CT and MRI findings and the differential diagnosis of teratomas.

Teratomas can be found in different organs of the body and may involve gonads, saccrococcygeal region, mediastinum and other sites. Intrathoracic teratomas always occur in mediastinum and less often arise within the lung. As teratomas mostly involve sex organs (gonads), they rarely occur as extra-gonadal tumors accounting for only 3% of all the cases and very small percentage of such tumors occur in mediastinum.

We report the case of a 22-year-old woman suffering from mature mediastinal teratoma, revealed by trichoptysis, which is an exceptional, but pathognomonic symptom of intrathoracic teratomas. Only eight cases of trichoptysis are reported, none of them involved a mediastinal localization. We present the endoscopic and radiologic presentation, its surgical management, and histologic particularities.
