Benign idiopathic retroperitoneal cyst: A case series of three patients

IMPORTANCE: Retroperitoneal cysts are a rare entity in the field of surgery and their management remains a clinical dilemma for many surgeons. This study addresses the clinical management of three benign retroperitoneal cysts which were presented in our hospital. OBJECTIVES: The objective of this case series is to explore the different clinical presentation of the retroperitoneal cyst (RPC). This study also aims at different tools of investigations especially role of CT scan in the diagnosis of RPC and finally the different treatment options available for RPC. METHODS: This is a single centered case series of three retroperitoneal cysts which were presented in surgical department of our hospital in the year 2016 and 2017. Total three patients were presented in this case series, two of them were females and one was male. Females were 13 years and 23 years age-old, male was 45 years old. Two of them admitted through the Outdoor Patient Clinic and one was presented to the surgical emergency. Informed consent from the patients and guardian (case1) has been taken. Research work has been reported in line with the PROCESS criteria. RESULTS: They were investigated and treated in our hospital. Two of them were diagnosed with retroperitoneal cysts preoperatively and one was diagnosed pre-operatively. In all three cases, surgery had been carried out and they had been observed in their early postoperative period and then followed up for two years. All biopsies had been followed and turned out to be benign idiopathic cysts. These patients have been followed up for 2 years after completion of their treatment. CONCLUSION: Retroperitoneal cysts in adults are an uncommon manifestation of abdominal pathology. Their presentation is quite vague. The rarity catches the surgeon off guard at times. Radiology plays a crucial role in defining these lesions and complete surgical excision remains the cornerstone of treatment for symptomatic and complicated patients.
