A Case Report of Teratoma Trio: Bilateral Ovarian Teratomas Coexistent With a Mesenteric Teratoma

Teratomas arise from totipotent primordial cells and unveil a mixture of tissues of tri-dermal or bi-dermal origin. They are the most common ovarian germ cell tumors. The extragonadal teratomas may be seen in the sacrococcygeal region, mediastinum, retroperitoneum, and intracranially. These can be either mature, which are considered benign, or immature and classified as malignant. Mature cystic teratomas have characteristic imaging features and a pre-operative diagnosis that can be reliably made. The case provided was of a 48-year-old female who was diagnosed with three separate intraabdominal masses that had typical imaging features of teratomas. An extragonadal mesenteric teratoma is itself a rare entity and its coexistence with bilateral ovarian teratomas, has rarely been described in medical literature. Hence, common pathologies in an uncommon location should always be considered while providing a list of diagnostic differentials, in such a patient scenario.
