RATIONALE: Splenic cysts (SCs) are rare findings in children, particularly the youngest. Here, we discuss a case that is useful for the differential diagnosis and treatment of SCs. PATIENT CONCERNS: A 9-year-old Albanian boy was admitted for severe abdominal pain localized mainly in the left hypochondrium for approximately 24 hours. His medical history was without significant clinical problems. DIAGNOSIS: Splenomegaly was diagnosed during the first clinical examination, and laboratory tests showed an increase in CA 125 and CA19-9. Abdominal ultrasonography showed splenomegaly with a large hypoechoic oval formation with well-defined margins and the presence of internal fine suspension spots; abdominal magnetic resonance imaging revealed a well-defined SC. The cystic lesion caused major effects on the neighboring organs, shifting them from their normal sites. INTERVENTIONS: Considering the mass's volume, an open splenectomy was performed. Upon histopathological examination, the lesion was characterized by a stratified squamous keratinized thick lining and brownish liquid contents consisting of lymphocytes, erythrocytes, and hemosiderin-rich macrophages. These features informed the diagnosis of a giant epidermoid SC. OUTCOMES: No complications occurred in the post-operative period, and blood exams revealed the quick normalization of CA 19.9 and CA 125 levels. The boy was discharged on the eighth post-operative day. No complaints were documented during the regular follow-up. LESSONS: This case shows that modern imaging techniques are useful for the differential diagnosis between epithelial mass and SCs of different origins. Open splenectomy has been the treatment of choice for years, but future studies should clarify whether more conservative methods are associated with positive long-term outcomes and if they can also be used for large SCs.

Abstract

RATIONALE: Splenic cysts (SCs) are rare findings in children, particularly the youngest. Here, we discuss a case that is useful for the differential diagnosis and treatment of SCs. PATIENT CONCERNS: A 9-year-old Albanian boy was admitted for severe abdominal pain localized mainly in the left hypochondrium for approximately 24 hours. His medical history was without significant clinical problems. DIAGNOSIS: Splenomegaly was diagnosed during the first clinical examination, and laboratory tests showed an increase in CA 125 and CA19-9. Abdominal ultrasonography showed splenomegaly with a large hypoechoic oval formation with well-defined margins and the presence of internal fine suspension spots; abdominal magnetic resonance imaging revealed a well-defined SC. The cystic lesion caused major effects on the neighboring organs, shifting them from their normal sites. INTERVENTIONS: Considering the mass's volume, an open splenectomy was performed. Upon histopathological examination, the lesion was characterized by a stratified squamous keratinized thick lining and brownish liquid contents consisting of lymphocytes, erythrocytes, and hemosiderin-rich macrophages. These features informed the diagnosis of a giant epidermoid SC. OUTCOMES: No complications occurred in the post-operative period, and blood exams revealed the quick normalization of CA 19.9 and CA 125 levels. The boy was discharged on the eighth post-operative day. No complaints were documented during the regular follow-up. LESSONS: This case shows that modern imaging techniques are useful for the differential diagnosis between epithelial mass and SCs of different origins. Open splenectomy has been the treatment of choice for years, but future studies should clarify whether more conservative methods are associated with positive long-term outcomes and if they can also be used for large SCs.
