Retroperitoneal Cyst
Introduction
Retroperitoneal cysts are believed to be benign tumours of retroperitoneum. They often attain large proportions before causing any symptoms. These rare tumours are derived from remnants of embryonal urogenital apparatus which includes tissues of both epithelial and mesothelial origin [1]. Treatment of choice is surgical excision. Incomplete excision often results in recurrence. The aim of presenting this case report, is to highlight the rarity of its presentation and its need for differentiation from unilateral hydronephrosis.

Case Report
61 year old female, presented with pain in left lumbar region of 5 months duration. Pain was insidious in onset, continuous dull aching in character and nonradiating. There were no aggravating or relieving factors. There were no associated bowel or urinary symptoms. She denied any history of fever or weight loss. General examination was noncontributory. Abdominal examination revealed mild fullness in left lumbar and iliac regions. Left renal angle was free. A 15×10 cms lump was felt in the left
Discussion
The retroperitoneal space is bounded posteriorly by the spine, psoas and quadratus lumborum muscles, superiorly by diaphragm and inferiorly by the levator muscles of pelvis. Anteriorly, this space is bounded by posterior parietal peritoneum. This potentially large space contains organs derived from ectoderm and endoderm that are all embedded in a loose network of connective tissue. This allows both primary and metastatic tumours to grow silently before the appearance of signs and symptoms.

2019, International Journal of Surgery Case ReportsCitation Excerpt :Surgical intervention is required in cases where these cysts tend to become symptomatic and when inherent complications like perforation, infection, and malignancy are expected. Both trans-abdominal and extra-peritoneal approaches can be used to approach and excise the cyst depending on the location [6]. A laparoscopic approach can also be undertaken in selected cases if enough expertise is available [9].
