Pregnancy-associated malignant retroperitoneal schwannoma: a case report
Matvienko M.D., Striganova I.A., Volchenko N.N., Lavrova A.M.
Rationale. Managing pregnancy complicated by cancer remains of high relevance. Analysis of case studies on pregnant women with tumors of various localizations is of great importance.
Case report. A 34-year-old female patient underwent a renal ultrasound in the second trimester of pregnancy, which revealed a retroperitoneal extraorgan mass by the right renal hilum and the L2–L3 vertebrae. The pregnancy progressed withoutt any complications, and the patient delivered vaginally at term. Postpartum, a contrast-enhanced CT scan was performed. The tumor was removed laparoscopically, and histological and immunohistochemical examination revealed a schwannoma.
Conclusion. The case report on retroperitoneal schwannoma detected during pregnancy deserves attention due to the rarity of the pathology, the complexity of diagnosis and management.
