Retroperitoneal Tumors in the Pelvis: A Diagnostic Challenge in Gynecology

Abstract

Retroperitoneal tumors can pose a diagnostic and therapeutic challenge to gynecologists because of their rarity, late presentation, and complex anatomical location in the retroperitoneum. This article reviews the diagnosis and management of retroperitoneal tumors in the pelvis, and highlights the potential pitfalls that may be faced by gynecologists.

Transperitoneal robotic resection of benign primary retroperitoneal tumors: can it be widely used?

“…Prior to surgery, we determined criteria to choose those patients who would undergo robotic laparoscopic surgeries as follows: Benign lesions based on preoperative evaluation. The tumor size was less than 8 cm. No abdominal surgery history.…”

“…They originate in the retroperitoneal spaces but not retroperitoneal organs and are always asymptomatic at the early stage . PRTs represent a problematic entity of surgical pathology because of their rarity, difficulty of diagnosis, high recurrence rate after surgical excision and unpredictable response to adjuvant therapy . The only radical treatment is surgical resection, but many of these tumors grow to be very large when they are diagnosed and are always accompanied by organ or vessel invasion; thus, a great challenge exists to achieve R0 resection.…”

Renal Remnant Presenting as a Large Retroperitoneal Mass in a Teenage Girl

“…6,7 Nonetheless the MRI features of most retroperitoneal tumors are non-specific, and pre-operative diagnosis and surgical planning remains a challenge. 4 In our case MRI was not performed as US and CT findings were considered sufficient. Arguably MR may have provided a more accurate pre-operative diagnosis.…”

“…This case underscores the importance of a broad differential when considering the etiology of a cystic pelvic mass. 4 Many pelvic masses have characteristic radiological findings and familiarity with these features is critical in surgical planning. In cases where ultrasound and CT findings are equivocal, MRI is frequently a useful adjunct.…”

Laparoscopically resected obturator nerve schwannoma: A case report

“…The classification of retroperitoneal tumors is divided into solid or cystic tumors. The differential diagnosis of solid retroperitoneal tumors usually includes lipoma/liposarcoma, leiomyoma/leiomyosarcoma, fibroma/fibrosarcoma, schwannoma/malignant schwannoma, ganglioneuroma, and metastatic retroperitoneal lymphadenopathy (). Ultrasonography is usually performed as the first‐line investigation but is best for detecting cystic lesions.…”
