Acute disseminated encephalomyelitis in a patient with monkeypox: a case report and radiological findings

Abstract

Monkeypox is a zoonosis caused by a double-stranded DNA virus of the Poxviridae family. It currently represents a global epidemic given its contagion reported in more than 31 previously non-endemic countries. We present the case of a 30-year-old male patient from Peru with a diagnosis of monkeypox by PCR test, who manifested an initial clinical picture of asthenia, adynamia, and odynophagia, with the appearance of pustular lesions on the lower lip and in the genital region associated with motor and sensory deficit of the lower limbs with altered state of consciousness, with subsequent findings of acute disseminated encephalitis by brain magnetic resonance imaging. This entity corresponds to an infrequent complication with only one case reported in the literature. The importance lies in knowing the possible imaging findings to suspect the diagnosis and expand the knowledge about this current disease.
