ABSTRACT
Modern imaging has come to occupy a pivotal role in the pre-/post- (and intra-) operative depiction of patient anatomy and disease localization in the sinonasal region, and can, on occasion, provide insights into pathology. Multi-detector row CT (MDCT) enables a patient to be rapidly scanned in the supine position, resulting in submillimetre slices that can be reformatted, in high resolution, in axial, coronal or sagittal planes. At the extreme end of the spectrum, with markedly ­viscid and dehydrated secretions, a signal void is produced on all imaging sequences. Sinonasal anatomy is subject to tremendous variation and is virtually unique to any one individual such that plain radiographic and, more recently, CT assessment of sinus anatomy are well-recognized techniques for victim identification in forensic investigation. The diagnosis of rhinosinusitis is largely a clinical/endoscopic one. Acute invasive fungal sinusitis (AIFS) usually occurs in immunocompromized patients and is a rapidly progressive, potentially fatal condition.
