[Non-parasitic splenic cysts]

Nonparasitic cysts of the spleen are uncommon and often result from blunt abdominal trauma. Nonsurgical management of blunt splenic injuries increases the number of observations of the post-traumatic cysts. Complications (infection, rupture and hemorrhage) are lifethreatening, difficult to diagnose and require urgent surgical management. Until recently, splenectomy has been the primary choice of treatment of these cysts. Small (< 4 cm) asymptomatic post-traumatic pseudocysts stand a reasonable chance of involution with time (3-36 months) and so may be initially observed. Splenic preservation by partial splenectomy, enucleation or by marsupialization is actually recommended in children when technically feasible. Splenectomy is required for voluminous, central, multifocal cysts, in the presence of complications and in the adults with low immunologic risk. The Authors report 5 cases of large cysts successfully treated by splenectomy with one 12-year-old girl treated in emergency for infection by Salmonella.
