Wandering Spleen Complicated by Thrombocytopenia, Acute Appendicitis, and Sepsis: A Case Report and Literature Review

Wandering spleen (WS) is a rare condition often linked with torsion or infarction, but its association with Bochdalek hernia, acute appendicitis, and thrombocytopenia is exceptionally rare. We present a case of a nine-year-old girl who was admitted with acute abdominal pain, later diagnosed with WS, Bochdalek hernia, and acute appendicitis. A literature search was performed on PubMed and Google Scholar on 30 May 2024 with keywords including "Wandering spleen" and ("Bochdalek Hernia" OR "Sepsis" OR "Acute Appendicitis" OR "Thrombocytopenia"). The management was complicated by severe thrombocytopenia and post-operative sepsis, with <i>Klebsiella pneumoniae</i> as the causative agent. Imaging revealed an abnormally located spleen and significant splenic enlargement over time. The patient's condition was managed non-operatively concerning the WS, avoiding splenectomy due to the risks of post-splenectomy sepsis. Instead, laparotomy was performed to address the appendicitis and diaphragmatic hernia. The patient experienced post-operative complications, including a seizure and persistent fever, which resolved with appropriate antibiotic therapy. This case underscores the complexity of managing WS with concurrent severe conditions, highlighting the importance of individualised treatment strategies. It also emphasises the need for further studies to explore optimal treatment modalities for such rare and complex presentations. This case serves as an educational example in clinical settings, demonstrating the challenges and considerations when treating multiple rare pathologies simultaneously.
