BACKGROUND Mature cystic teratomas are usually found in the ovaries. They are bilateral in 10 to 15% of cases and multiple cystic teratomas may be present in one ovary. The aim of this study is to clarify if development of mature cystic teratomas of the ovaries in a single host is metachronous or due to autoimplant or recurrence. CASE PRESENTATION We report a woman with bilateral mature cysti...

Retroperitoneum is a relatively uncommon site for pediatric teratomas. Rarely, such tumors can have an intraspinal extension and few cases of retroperitoneal teratomas associated with spinal dysraphism have been reported. Teratomas consist of tissues arising from all three embryonic layers. However, mature renal tissues in the form of glomeruli and tubules are sparingly found in teratomas. A 15...

INTRODUCTION Fetal tumors are relatively rare and the early prenatal diagnosis enables the prediction of possible complications and decision for appropriate treatment. This paper deals with the role of ultrasonography and magnetic resonance imaging in the early prenatal diagnosis of sacrococcygeal teratoma. CASE REPORT A 21-year-old primigravida was found to have a large sacrococcygeal tumor ...

Teratomas of the central nervous system are rare and are frequently found in children and young adults. Cystic teratomas found in infancy is a well-recognized but infrequent entity. Intracranial teratomas,like teratomas in general, tend to arise from midline structures such as the pineal gland, but has rarely been found in the third ventricle. We report a rare case of a 6-month-old infant with ...
