title: [MRI of traumatic anosmia].
abstract: On MRI, the authors were able to demonstrate the contused lesions of bilateral rectal gyri near the crista galli in all of five cases of traumatic anosmia. Thin slice coronal and sagittal images of MRI were very useful for detecting the lesions. Conventional CT scans failed to demonstrate the lesions in 3 out of the 5 cases, but, even in these cases, MRI was able to clearly depict the contused lesions of bilateral rectal gyri. Therefore, the depicted lesions of bilateral rectal gyri on MRI can be evidence of traumatic anosmia and this may be very significant in medico-legal cases.
