Challenges in Diagnosing Post-Splenectomy Cytomegalovirus Mononucleosis.

Unlabelled: Cytomegalovirus (CMV) infection is often asymptomatic. However, in certain individuals, it can cause non-specific signs and symptoms that maybe hard to recognise. The condition may therefore be overlooked or misdiagnosed, leading to prolonged illness and serious sequelae. In this case report, we present a rare instance of CMV infection in an HIV-negative patient who had a remote history of splenectomy and was experiencing prolonged fever and markedly elevated white blood cell (WBC) count.

Learning Points: The clinical presentation of CMV infection in a post-splenectomy patient can be intricate and deceptive, involving non-specific symptoms such as prolonged fever and a markedly elevated WBC count.The decision on treatment among individuals without apparent risk factors (such as AIDS, transplant, or cancers) led to in-depth deliberations and discussion.Post-splenectomy patients with CMV infection may exhibit prolonged illness, potentially leading to severe consequences if left untreated.
