Splenic pseudocysts are nonparasitic cyst without epithelial lining. We report this case especially by its way of revelation, its large size and its per operative presentation which needed total splenectomy. To this opportunity, we discuss the diagnostic procedure and therapeutic indications.
A twenty-year old Senegalese woman, was admitted with a three-month history of spontaneous abdominal mass associated with a pain. Ultrasonography and CT scan found the giant splenic pseudocyst with a diameter of 20 cm which needed a total splenectomy by median laparotomy.
Usually, symptomless splenic cysts are untreated. When surgical treatment is indicated, recommendations are to preserve splenic parenchyma by partial splenectomy or fenestration especially by laparoscopy. Total splenectomy retains some guidance.

Splenic pseudocysts are nonparasitic cyst without epithelial lining . Those are mostly secondary to post traumatic haematomas. Without a recent trauma history, there is no clinical or radiological feature which distinguishes them to epidermoid cyst . Distinction may be made at histology. Surgical management of these symptomatic pseudocysts promotes spleen parenchyma preservation. We report this case especially by its way of revelation, its large size which needed total splenectomy. To this opportunity, we discuss the diagnostic procedure and therapeutic indications.
Management of these splenic cyst is threefold: What is the nature of the cyst? Should we operate and what surgery do? Cysts are classified as congenital cyst, pseudocyst, parasitic and tumor cysts. Our case was nonparasitic splenic cysts in the absence of infectious syndrome and non-tumoral on imaging. Martin Fowler , have made a classification distinguishing between congenital cysts (CC) that have an epithelial lining and post traumatic pseudo cysts (PC) which do not. Therefore, the distinction between CC and pseudo cyst may be made at histology. Without the recent notion obvious trauma, there is no clinical or radiological feature which distinguish them. They appear both in the CT scan thin-walled, hypodense, and without enhancement after contrast injection . This distinction based on the presence or absence of epithelial lining is challenged by Morgenstern , which considers that several CC are wrongly considered as PC. Indeed, the wall is discontinuous and only a careful histological reading layout to suggest his absence or his presence. The lack of trauma and epithelial lining induced our case was a pseudo cyst by resorption of a hematoma. The second concern relates to the operative indication. Usually, symptomless splenic cysts are untreated. Indeed, the complications over time are rare. Cowles , found, in a total of 191 cases monitored a complication rate of 5.2% in type of rupture and infection. Our surgical indication was based on the size of splenic pseudocyst which carried out an abdominal mass exposed to a risk of rupture. The surgical treatment of these splenic cysts is partial or total splenectomy, and fenestration. Laparoscopic fenestration, however, is associated with a significant recurrence rate. Schier , found a recurrence rate of 64% within an average of 1 year, despite all the procedures used to treat residual cavity (omentum package, argon destruction). To prevent the complications of total splenectomy, partial splenectomy appears to be the best indication but leaving at least 25% of the splenic parenchyma and with access to effective means of sliced section hemostasis. We conducted a total splenectomy because of an insufficient residual parenchyma and the high risk of bleeding from a partial splenectomy.
Splenic pseudo cysts are benign formations often secondary to the resorption of a hematoma. Asymptomatic forms do not belong to any treatment. When they are symptomatic, partial splenectomy is superior to laparoscopic fenestration in terms of recurrence. Total splenectomy retains some guidance.
