Normal anatomy. Coronal soft tissue (a) and bone window (b) CT images at the level of the olfactory bulb, demonstrating the normal anatomy of the sinonasal compartment (SC) and anterior skull base. The olfactory nerves within the SC and olfactory recess (OR) ascend intracranially via perforations within the cribriform plate (CP). The CP is bounded laterally via the lateral lamella (LL), the crista galli (CG) is seen as a midline projection, and the fovea ethmoidalis (FE) forms the roof of the ethmoid. The position of the olfactory bulb (OB) within the olfactory groove is just discernible on the soft tissue window image (a). The gyrus rectus (GR) and orbital gyrus (OG) are separated by the olfactory sulcus (OS)
