TY - JOUR AU - Lie, Geoffrey AU - Wilson, Alexander AU - Campion, Thomas AU - Adams, Ashok PY - 2021 DA - 2021/01/07 TI - What's that smell? A pictorial review of the olfactory pathways and imaging assessment of the myriad pathologies that can affect them JO - Insights into Imaging SP - 7 VL - 12 IS - 1 AB - The olfactory pathway is composed of peripheral sinonasal and central sensorineural components. The wide variety of different pathologies that can affect the olfactory pathway reflect this complex anatomical relationship. Localising olfactory pathology can present a challenge to the reporting radiologist. This imaging review will illustrate the normal anatomy of the olfactory system and describe a systematic approach to considering olfactory dysfunction. Key concepts in image interpretation will be demonstrated using examples of olfactory pathway pathologies.
