A Microbial Old Friend with a New Face: A Rare Case of Pyrexia of Unknown Origin and Leukemoid Reaction.

We present a case of a young male, who presented to us with high-grade fever for more than four weeks, refractory seizures, multiple subcutaneous palpable lumps, and evidence of leukocytosis with predominant left shift on the peripheral smear. The classic "starry-sky" appearance on imaging, generalized muscular uptake on positron emission tomography-computerized tomography scan, and positive serology led to a diagnosis of disseminated cysticercosis. He responded to oral steroids. To the best of our knowledge, disseminated cysticercosis presenting as pyrexia of unknown origin and with a leukemoid reaction has never been reported in literature.
