Pediatric Presacral Masses

Sacrococcygeal teratoma in an adolescent.

“…Mature teratoma (also known as benign teratoma) contains epithelium-lined structures, mature cartilage, and striated or smooth muscle. Immature sac (7). This could be excluded by our MRI findings.…”

“…Malignant teratoma has malignant tissue of germ cell origin, such as germinoma and choriocarcinoma. Malignant teratoma has a predominant solid component; hemorrhage and necrosis are common (7). Tumors containing malignant, nongerm cell elements, including adenocarcinoma and squamous cell carcinoma, are referred to as teratoma with malignant transformation.…”

“…Calcifications are seldom observed in malignant tumors (7). At CT or MRI, SCTs appear as heterogeneous, well-defined masses with mixed cystic and solid components.…”

A Case of Childhood Ovarian Teratoma

“…Most ovarian and testicular tumors are of germ cell origin. [1][2][3] Tumors outside the gonad are called extragonadal tumors. These tumors also occur along the midline path and can be found in the head, chest, abdomen, pelvis and sacrococcygeal (lower back) area.…”

Sacrococcygeal sinus angle: as a new anatomic landmark for the posterior approach of presacral lesions

“…A wide range of pathological conditions can be seen in the presacral region [2]. Congenital masses such as teratomas, chordomas, dermoid or epidermoid tumors; tumors arising from neural elements such as schwannomas, neurofibromas and neuroblastomas; and mass lesions showing distinct features such as infiltrative rectum tumors, metastases, rhabdomyosarcomas and lymphangiomas can be seen in the presacral region [1,3,9,10,13]. Since the presacral region involves several different anatomical structures and related pathologies, it is a common point of interest of different disciplines and generally requires a multidisciplinary approach [2].…”
