PET-CT save a day in deep-seated infection

Ventriculoperitoneal (VP) shunt infection is one of the common reasons of shunt malfunction. However, it is a well-known scenario that most patients with VP shunt infection present with non-specific complaints like fever and abdominal discomfort. Lumbar puncture analysis and blood culture could be unrevealing which may delay the diagnosis and subsequent management. Thus, the introduction of 2-[18F]-fluoro-2- deoxy-D-glucose (2-[18F]-FDG) positron emission tomography computed tomography (PET-CT) is filling the clinical gap. PET-CT is now being recognized as the imaging modality for shunt infection with moderate clinical suspicion. Our case underlined the importance of early PET-CT in pyrexia of unknown origin in identifying deep-seated infection.
