An incidental diagnosis of a giant paraovarian cyst in a female teenager: A case report

RATIONALE: Paraovarian cysts (PCs) are cystic tumors that can be encountered between the ovarian hilum and the ovarian fimbria located within the mesosalpinx and broad ligament, being usually diagnosed within the 3rd and 4th decade of life. PATIENT CONCERNS: We report the case of a 15-year-old female admitted in our clinic for consciousness loss, who was incidentally diagnosed with a giant pelvic cystic at ultrasound. DIAGNOSES: The magnetic resonance image showed a cystic mass of 170/140/85 mm, suggesting an origin from the left ovary, reaching the subhepatic area. INTERVENTIONS AND OUTCOMES: The surgical intervention revealed 3 PCs, a giant one and 2 smaller ones within the large ligament. The cysts were removed by laparoscopic approach, and the histologic examination did not reveal any signs of neoplasia. LESSONS: In addition to their rarity, giant PCs can be an incidental diagnosis in patients presenting unrelated symptoms resulting in increased difficulties related to the diagnosis. Moreover, the imagistic tools might not establish precisely the origin of these cysts, and therefore, the final diagnosis and treatment approach could be determined sometimes only during the surgical intervention.
