Fungal Sinusitis: Magnetic Resonance Image Findings on Immunocompromised Patients

AbstractPurpose of ReviewEven though there are latest advances on immunocompromised patient care, the mortality by invasive fungal infection still high. Invasive aspergillosis is one of the main complications during immunosuppression and on hematological malignancy patients, with a mortality varying from 50 to 80%. Imaging studies are fundamental on the evaluation of fungal suspicion, and concerns related to radiation dose on image examinations are high nowadays. Magnetic resonance imaging should be considered on brain and facial sinuses evaluation to reduce radiation exposure.Recent FindingsWhenever fungal material is present, the sinus content becomes a low STIR signal and a middle-high signal on T1. The T2 low signal or signal void is attributed to metal concentration, as well as the high protein and low free water content. Adjacent structures should also be evaluated to characterize disease involvement and its extension.SummaryMRI should be used to reduce radiation exposure on the evaluation of fungal suspicion on immunocompromised patients.
