RESUMEN

INTRODUCTION AND IMPORTANCE: Splenic cysts are classified as true cysts, or pseudocysts, and larger cysts tend to be symptomatic, requiring management which has evolved to include spleen-sparing procedures to minimize the risk of overwhelming post-splenectomy sepsis (OPSS) Pitiakoudis et al. (2011), Hansen and Moller (2004), Knook et al. (2019) [1-3]. Total splenectomy remains the gold standard management, and the importance of this case is the uncommon spontaneous occurrence of a pseudocyst, and the importance to pre-operatively consent and prepare the patient for total splenectomy would intra-operative conditions not allow for spleen-preserving techniques. CASE PRESENTATION: CS, a 21-year-old lady, had two presentations to the emergency department with left upper quadrant abdominal pain. The only abnormality on assessment was a large splenic cyst on CT scan, which increased in size on re-presentation. She was consented for a splenic cyst fenestration, and for total splenectomy and optimized with vaccines would intra-operative conditions not allow for spleen-sparing. During the operation, the planes between the cyst and spleen parenchyma were ill-defined, and decision was made to proceed with total splenectomy to avoid bleeding complications. She recovered well, and was discharged 5 days post-operatively, and histology confirmed a pseudocyst (Figs. 1 and 2). CLINICAL DISCUSSION: The management of splenic cysts remains difficult and with no clear guidelines to uniform treatment. There are multiple spleen-preserving techniques developed to avoid OPSS (Agha RA, Franchi T, Sohrabi C, Mathew G, for the SCARE Group, 2020 [4]), however management remains individualized and case-specific. CONCLUSION: Pseudocysts can occur without splenic trauma or infarct. Management is case-based, and patients with large symptomatic cysts should be consented and prepared for total splenectomy would conditions not be safe for spleen-preserving interventions.
