University of Pennsylvania Smell Identification Test (UPSIT) results, represented by categories (derived from the manual [13]): anosmia, moderate or mild microsmia were identified; and magnetic resonance imaging (MRI) findings, which included paramagnetic sequences (represented by susceptibility-weighted imaging, SWI or T2* gradient-recalled echo, T2*GRE), of olfactory and auditory regions; CNVIII 8th cranial nerve
