Many investigators have described olfactory dysfunction among migraineurs. Olfactory stimuli can precipitate migraine, and olfactory hallucinations can occur as auras of migraines or as part of the symptom complex. Despite many reports linking olfactory phenomena and migraine, no evaluations of the olfactory abilities of migraineurs have been documented. To begin such assessments, sixty-seven consecutive migraine patients were given Pyridine odor threshold tests. Twelve of them (18%) scored as hyposmic or anosmic. In comparison, 1% of the general population of the U.S. is hyposmic or anosmic. Aside from possible diagnostic or methodological error, several possibilities may account for our result: migraine may induce olfactory pathology; olfactory pathology may induce migraine, or; a common pathogen may induce both olfactory dysfunction and migraine. The association of migraine with the emotional component of the limbic system has long been recognized, and our results strengthen its association with the olfactory component as well. Headache patients should be tested for olfactory loss and warned of such risks as inability to detect gas leaks and spoiled food.

The prevalence of abnormal perceptual experiences as symptoms of migraine attacks was determined in a consecutive series of 46 new female referrals to a migraine clinic. All patients met the diagnostic criteria of the International Headache Society for migraine with aura or migraine without aura and had no other serious physical illness. Seven patients (15%) reported abnormal perceptions (olfactory and/or gustatory hallucinations and distortions of body image) as part of most migraine attacks. A statistically significant association was found between these abnormal perceptual experiences and complaints of mood change, particularly increased depression and irritability, as part of most migraine attacks. It is suggested that spreading depression of cortical electrical activity may be responsible for the manifestations of temporal lobe and limbic system dysfunction.

Twelve cases of olfactory groove meningioma had been reported. The first symptom of the disease was dysfunction of the olfactory nerve. Rhinologists are responsible for the early diagnosis of the disease. The very important diagnostic points of the disease are dysfunction of the olfactory nerve; visual impairment; headache; Foster-Kennedy's syndrome and the CT scan. The clinical features, diagnosis and treatment of the 12 cases were discussed. Early diagnosis of the diseases is very important for the performance of the operation via the rhino-anterior fossa approach.

A rare case of ectopic meningioma of the ethmoid sinus is reported. A 57 year-old male patient was admitted with complaints of anosmia and headache. Computed tomography revealed a relatively high-density mass in the bilateral ethmoid and sphenoid sinuses. The mass was markedly enhanced after intravenous administration of contrast medium. The cerebral angiography showed tumor stains fed by bilateral internal and external carotid arteries with right side dominance. The tumor in the ethmoidal sinus was removed by otolaryngologists at first and then the tumor in the sphenoid sinus was removed using sublabial transseptal sphenotomy. The histological examination resulted in a diagnosis of transitional meningioma with psammoma bodies. The tumor in this case is suspected to have originated from heterotopic meningocytes or meningocytes accompanying the perineural sheath of the olfactory nerve.

The occurrence of perceptual disturbances in migraineurs, particularly during the headache-free interval, has been scrutinized rather rarely. This subject was studied via a mail survey in 134 patients presenting perceptual changes before or during their migraine attacks. The patients had to complete a 5-part questionnaire covering history, events before, during as well as after the attack, and the attack-free interval. Sensory alterations during the headache-free interval were not reported by 36.6% of the patients. Alterations of equilibrium and/or spatial orientation, mainly susceptibility to motion sickness, were present in 47.8%, increased sensitivity to cold or heat in 40.3%, intolerance of tight clothes or being touched in 34.3%, altered visual function in 32.8%, changes in olfactory acuity in 31.1%. These percentages show that these 5 types of interictal sensory disturbances may not be rare in migraineurs. The exact frequency of these symptoms and how they correlate with perictal phenomena, sex, age and disease characteristics has to be further studied.

Twenty patients with complex neuropsychologic symptoms associated with classic migraine were selected from a group of 200 patients with vascular headache. Twenty types of symptoms were found and grouped into six categories (language, visual symptoms, cognitive-dysmnesic symptoms, olfactory-gustatory hallucinations, automatisms, and somatosensory symptoms). Some of the symptoms found have apparently not been reported previously. The importance of the analysis of this complex neuropsychologic set of symptoms and of the possible consequences of complicated, frequent vascular headache is emphasized.

An esthesioneuroblastoma, a rare malignancy of the olfactory nerve, was identified with bone imaging in a four year old male who presented with a history of headaches and proptosis of the right eye. Correlation with CT is provided.

Thirty-nine patients with esthesioneuroblastoma are reviewed. The presentation of the tumor, symptomatology, investigation, and treatment are discussed. A recommended treatment regimen is outlined. Histologic typing is valueless in predicting tumor behavior. An illustrative and difficult case of recurrent base of skull esthesioneuroblastoma is presented. The resection performed is described, and the problem of extradural oropharyngeal communication is discussed. The solution was to use a temporalis and galeal frontalis flap. Reconstruction was with an external and intraoral prosthesis. Optimal treatment in a fresh lesion is radical surgery with or without radiation therapy. Esthesioneuroblastoma is a rare and often misdiagnosed malignant tumor of the olfactory epithelium. Originally described by Bergen et al. in 1924 as "esthesioneuroepithelioma olfactif," it was introduced into the North American literature by Schall and Lineback in 1951. Since then, fewer than 200 cases have been collected. The various terms used to describe it--olfactory esthesioneuroblastoma, esthesioneurocytoma, and olfactory neuroblastoma--all denote origin from the neural crest. The sensory nerves of smell are short bundles of fibers that originate in the olfactory bulb and pass through the cribriform plate to the olfactory area of the nasal mucosa. This mucosa is located in the most superior part of both nasal fossae. Thus the usual primary sites of occurrence include the superior nasal cavity or nasal septum, and turbinates, the ethmoid, or the cribriform plate, although an extranasal site of origin has been suggested. Symptoms are usually progressive and range from nasal obstruction or epistaxis to diplopia, ocular pain, and headaches in the more advanced disease state.(ABSTRACT TRUNCATED AT 250 WORDS)

A rare case of olfactory neuroblastoma presenting symptoms as a brain metastasis is reported. A 47-year-old-man was admitted to Yamagata City Hospital complaining of head heaviness and headache attack. Neurologically, bilateral slight choked disc and right anosmia were found. The otolaryngologist in this hospital pointed out a reddish-purple polypoid tumor in the right nasal cavity. But there were no episodes of nasal bleeding or obstruction before admission. CT scan on admission showed the tumor density in the right upper nasal cavity and ethmoid sinus, which partially infiltrated into the orbital cavity, and enhanced heterogenous high density mass in the inner basal portion of the right frontal lobe. Carotid angiogram revealed a small tumor blush in the ethmoid region and avascular mass lesion in the right frontal region. On the 11th hospital day, surgical biopsy of the nasal tumor was performed by the otolaryngologist and the evident tumor cells in the fibrous tissue were observed. So the endonasal removal of the tumor and the total removal of the intracranial tumor were achieved. On operation, the continuity of intracranial tumor and nasal tumor was not observed. The histological pictures of both tumors were similar and the diagnosis was olfactory neuroblastoma. From histological and operative findings, we concluded the intracranial tumor was metastatic lesion from nasal origin. CT scan taken after the operation showed the tumor rested only in the right ethmoid sinus.(ABSTRACT TRUNCATED AT 250 WORDS)
