Bernhardt- Roth syndrome as a rare manifestation of a giant abdominal cyst

The article describes a clinical case of the “lateral femoral cutaneous nerve” syndrome (Bernhardt-Roth syndrome, paresthetic meralgia) in patient N.1965, who was admitted to GBU RO OKB on 09/23/2024 with a clinical picture of an abdominal cyst of unknown origin. As a result of the diagnostic examination, collection of anamnestic data and the clinical picture, a preliminary clinical diagnosis was established: a cyst of the retroperitoneal space. An MRI examination of the patient was not possible due to a BMI of more than 50 kg/m 2 . The patient was concerned about severe burning pain on the lateral surface of the thigh, numbness during the last two weeks, abdominal enlargement during the last 3 months, and pulling pains in the hypogastrium from 6:00 a. m. On the second day of hospitalization, the patient showed positive peritoneal symptoms, as a result of which it was decided to perform a diagnostic laparotomy. An examination of the abdominal organs revealed a 30×40 cm bulky formation growing from the right ovary with a twisted vascular pedicle, as well as about 200 ml of hemorrhagic effusion in the pelvis and through the lateral canals. A team of surgeons and gynecologists performed tumor resection with stitching of the vascular pedicle, left- and right-sided adnexectomy. On the very first day after the operation, the patient noted a significant improvement in her condition, the symptoms of compression of the lateral cutaneous nerve of the thigh disappeared on the first day after the operation. On day 5, the patient was discharged under the supervision of a surgeon at her place of residence in a satisfactory condition.
