Multiple intraabdominal parasitic cystic teratomas

Area of Science:

• Gynecology
• Surgical Oncology
• Diagnostic Imaging

Background:

• Ovarian dermoid cysts can undergo autoamputation and reimplantation, leading to omental teratomas.
• Abdominal pain and palpable masses are common presenting symptoms.
• Diagnosis of omental teratomas is challenging despite advanced imaging techniques.

Observation:

• A patient previously treated for an ovarian dermoid cyst presented with recurrent symptoms.
• Multiple intraabdominal masses were found, including on the abdominal wall, omentum, and pouch of Douglas, as well as an ovarian cyst.
• Laparoscopic surgery was performed for complete mass removal.

Findings:

• The patient had extensive, widespread parasitic dermoid tumors, a presentation not previously reported in medical literature.
• Computed tomography and ultrasonography aided in diagnosis, but omental localization remained difficult.
• Complete laparoscopic excision of all masses was achieved.

Implications:

• This case expands the understanding of dermoid cyst recurrence and spread.
• It underscores the diagnostic challenges associated with omental teratomas.
• Laparoscopic management is feasible for extensive intraabdominal parasitic dermoids.
