An Unusual Case Of Microascus Brain Abscess In An Immunocompetent Child And A Review Of The Literature

We present a case of brain abscess in an immunocompetent child due to the dematiaceous fungus Microascus cinereus, an organism commonly found in soil and stored grains. The etiologic agent was demonstrated by direct microscopy and culture. The patient responded well to surgical excision of abscess along with a course of amphotericin B and voriconazole. Microascus species have emerged as significant invasive pathogens especially in the immunocompromised patients. To the best of our knowledge, this is the first reported case of brain abscess caused by M. cinereus in an immunocompetent individual with no underlying risk factors.
