Olfactory schwannomas are very rare. For this reason they have never been diagnosed preoperatively. We report a case and describe the CT and MR imaging findings. Clinically, the young age of presentation, and radiologically the presence of bone scalloping, and the absence of both bone sclerosis and a dural tail, may help in the differential diagnosis ...

Olfactory neuroblastoma is a rare tumor. Nasal endoscopy typically identifies a soft mass arising from the olfactory cleft. Computer tomography and magnetic resonance imaging are mandatory for staging (in association with 18F-fluorodeoxyglucose positron emission tomography) in high-grade and/or high-stage tumors.

Olfactory esthesioneuroblastoma
The Journal of Laryngology & Otology, 1976Esthesioneuroblastomas are malignant tumours, usually of slow, invasive growth and low metastatic rate. Skeletal destruction must be assumed to be common, but is often demonstrable only by tomographic sections. Clinically these tumours do not differ from others of the same site, so that the diagnosis has to be based upon the histological appearances ...

Unravelling the mechanisms of learning and memory can, and should, be tackled at many levels. Discovery of the huge family of odourant receptor genes provided olfaction with 'molecular' respectability similar to that afforded to the visual system. Consequently, molecular studies have dominated the olfactory literature this past year, even to the point ...

This chapter discusses the anatomic basis of the olfactory sensation (smell) and symptoms and signs caused by its impairment. The primary neurons of the olfactory system are the bipolar cells located in the olfactory epithelium of the nasal mucous membrane (Figure 6-1).

Clinical Diagnosis and Current Management Strategies for Olfactory Dysfunction: A Review.
JAMA Otolaryngology - Head and Neck Surgery, 2019Importance Olfactory dysfunction affects approximately 20% of the general adult population. It is associated with reduced quality of life and important health care outcomes such as neurodegeneration and death.

The term imprinting is used to refer to biologically relevant learning during a sensitive period defined by a particular developmental stage or physiological state. Although olfactory imprinting may occur at any age, and some of the best-studied paradigms involve adult animals, recent reports of long-term memory for odorants experienced during prenatal

To provide a comprehensive review of the literature focusing on the recent advances in the diagnosis and management of olfactory neuroblastoma.Multimodality treatment is usually recommended for the majority of ONB cases. Recent advances in surgical approaches include the evolving role of endonasal endoscopic surgical resection and reconstruction.

Axons from the olfactory bulb (OB) project to multiple central structures of the brain, many of which, in turn, send axons back into the OB and/or to one another. These secondary sensory regions underlie many aspects of odor representation, valence, and learning, as well as serving some nonolfactory functions, though many details remain unclear.
