Giant Calcified Retroperitoneal Teratoma.

Area of Science:

• Oncology
• Pediatric Surgery
• Radiology

Background:

• Retroperitoneal teratomas are rare, particularly in adults, accounting for only 4% of primary teratomas.
• These tumors are more commonly diagnosed in infants and children.
• Adrenal gland involvement by teratoma is an infrequent presentation.

Purpose of the Study:

• To report an unusual case of a large retroperitoneal teratoma involving the adrenal gland in a adolescent.
• To illustrate the diagnostic imaging findings of such a rare tumor.
• To highlight the successful management of this rare entity.

Main Methods:

• Diagnostic imaging including X-ray and CT abdomen was utilized.
• The tumor was characterized by cystic and calcified components.
• Surgical excision was performed for treatment.

Main Results:

• A large (12 x 10 cm) calcified cyst was identified in the left abdomen.
• The cyst was confirmed to be a retroperitoneal teratoma involving the adrenal gland.
• The patient underwent successful surgical removal of the tumor.

Conclusions:

• Retroperitoneal teratomas, even when large and calcified, can be successfully treated with surgical excision in adolescents.
• Multidetector CT is valuable in diagnosing complex retroperitoneal masses.
• This case underscores the importance of considering teratomas in the differential diagnosis of abdominal masses in young patients.
