Abstract / Summary
Ovarian fibromas are uncommon benign sex cord-stromal tumors that frequently present as unilateral solid masses and may mimic ovarian malignancy, particularly in postmenopausal women.Preoperative diagnosis remains challenging because imaging findings and tumor markers often overlap with those of other adnexal lesions.We present the case of an ovarian fibroma initially misdiagnosed as an endometrioma, illustrating the limitations of preoperative assessment.We report the case of a 60-year-old postmenopausal woman with an incidentally detected right adnexal mass initially interpreted as an endometrioma on transvaginal ultrasound and computed tomography (CT).The patient subsequently underwent laparoscopic resection, and histopathological examination confirmed the diagnosis of ovarian fibroma.Ovarian fibromas may mimic other adnexal masses, making preoperative diagnosis challenging.Imaging studies and serum tumor markers have limited specificity and may be insufficient to reliably distinguish these tumors from other ovarian lesions.In postmenopausal women, persistent solid adnexal masses generally warrant surgical exploration regardless of ancillary findings.Therefore, definitive diagnosis of ovarian fibroma relies on histopathological examination.Ovarian fibroma remains an important differential diagnosis of solid adnexal masses in postmenopausal women.The limitations of preoperative assessment reinforce the role of surgical excision, while histopathological examination remains the gold standard for definitive diagnosis.
