Prenatal diagnosis of cryptorchid testicular teratoma

Abstract

Testis follows a predictable course during its stepwise descent from its site of origin in the lumbar region to its final destination in ipsilateral hemi-scrotum. Undesended (cryptorchid) testis is more prone for neoplastic transformation. Testicular teratoma is rare relative to ovarian teratoma and occurs rarely prenatally than postnatally. Teratoma is composed of derivatives of three germ layers. Ultrasound with color Doppler is the most commonly used modality for assessment of prenatal status. Prenatal diagnosis of cryptorchid testicular teratoma involves identification of well-defined, complex solid-cystic lesion with calcifications along the path of testicular descent and absent testis in ipsilateral hemi-scrotum at 36 weeks of gestation. Complications associated with cryptorchid testicular teratoma include torsion, hemorrhage, or malignant transformation. Early diagnosis is important to avoid complications, and hence, ultrasound imaging features play an important role in diagnosis.

Fetal Testicular Teratoma: Report of a Prenatally Undiagnosed Case and Literature Review

“…We found 8 case reports of prenatally diagnosed fetal teratoma in the PubMed database (5)(6)(7)(8)(9)(10)(11)(12) , and we collected all the ndings, including ours, to provide a general clinical picture summarizing the 9 cases. Most prenatal teratomas were identi ed during the third gestational trimester (7/9); the masses were all located in the pelvic and abdominal cavities (9/9), on left (6/9) and right (3/9) sides.…”
