ABSTRACT

Mycetoma is a chronic subcutaneous granulomatous infection caused by either true fungi (eumycetoma) or filamentous bacteria (actinomycetoma). Nocardia brasiliensis is a highly prevalent etiologic agent, especially in Mexico. Classified by the World Health Organization (WHO) as a neglected tropical disease, mycetoma progresses slowly, potentially involving deep structures like muscles, fascia, and bones. Imaging is crucial for early and differential diagnosis, as well as for accurately assessing the infection’s anatomical extent.
This article presents a clinical case of actinomycetoma caused by Nocardia brasiliensis with paravertebral and neurological involvement. Magnetic resonance imaging (MRI) revealed extensive soft tissue inflammation and spinal cord compression. The diagnosis was confirmed by direct examination, culture, and biochemical tests. We emphasize the importance of imaging studies, particularly MRI, for detecting the full extent of infection in cases with atypical or subtle clinical manifestations. We also discuss characteristic imaging findings, underscoring radiology’s essential role in managing and predicting the prognosis of mycetoma in uncommon locations.
