Parasitic Omental Dermoid Mimicking Adnexal Mass—A Diagnostic Dilemma: A Case Report

REPORTthe omentum (Fig. 4).The uterus showed features of intramural fibroids, adenomyosis, and chronic cervicitis.The patient was discharged on postoperative day 4 and was doing well on further follow-up in the outpatient department (OPD). DiscussionOmental teratomas are extremely rare, with the majority thought to originate from auto-amputated ovarian dermoid cysts, which subsequently reimplant into the omentum. 6hronic torsion can lead to necrosis and detachment of the ovarian cyst, allowing it to survive as a parasitic mass due to the rich vascularity of the omentum. 7These lesions may mimic adnexal tumors, especially when the ovaries are radiologically or intraoperatively normal. 8iagnosis is challenging due to nonspecific imaging findings.While modalities such as ultrasound, computed tomography (CT), and MRI may suggest a teratoma, they cannot reliably determine the exact site of origin in parasitic lesions. 9,10Hence, clinical suspicion and surgical planning with relevant consent must be established in advance.Histopathological confirmation remains essential for accurate diagnosis and classification.
