Splenectomy for E. coli abscess: A case report with a difficult preoperative diagnosis and unclear pathogenesis.

INTRODUCTION: Isolated splenic abscess is a rare clinical condition and remains a diagnostic dilemma. Clinical presentation is non-specific and the diagnosis is often delayed. Ultrasonography and CT scan are the gold standard. The treatment is still controversial: antibiotic therapy, percutaneous drainage (PCD) or splenectomy. CASE PRESENTATION: We present the clinical case of a patient, admitted to our Department because of abdominal pain, without fever. The preoperative radiological assesment showed three intrasplenic liquid collections, whose differential diagnosis was made between hematic collection and abscess. The treatment was splenectomy. The samples of collected liquid were positive for Escherichia Coli. CONCLUSION: In case of splenic abscess, splenectomy is the best therapeutic choice. The other therapeutical options like antibiotic therapy and PCD, can be used only in particular cases, but without the same efficacy.
