Extraocular muscle pareses in patients with Cushing syndrome are virtually always associated with a greatly enlarged pituitary tumor and with advancement on oculomotor nerves. The present report concerns a patient with a rapidly progressive adrenocorticotropic hormone (ACTH)-dependent hyperadrenocorticism and sudden onset of an unilateral third nerve paresis. The patient had no demonstrable pituitary tumor. After a total adrenalectomy and correction of hyperadrenocortisolism, his third nerve paresis subsided. Ocular paresis may occur in a patient with Cushing syndrome even in the absence of mechanical involvement of ocular nerves by a pituitary tumor.

Upper airway obstruction resulting from a paratracheal abscess developed insidiously and led to the death of a 43-year-old woman with multiple sclerosis. Repeated nasogastric intubation, required by an exacerbation of bulbar symptoms, may have initiated this unusual infection. Corticotropin and corticosteroid therapy may have impaired immunologic competence and masked fever and other symptoms of inflammation. Hoarseness and inspiratory stridor should not be attributed to laryngeal paresis in patients with multiple sclerosis unless other causes of airway obstruction have been excluded by appropriate diagnostic studies.

A 24-year-old woman presented with a rare adrenocorticotropic hormone (ACTH)-positive pituitary adenoma in the cavernous sinus, manifesting as sudden onset of oculomotor nerve paresis. Neuroimaging revealed a tumor in the cavernous sinus bulging into the subdural space. There was no continuity between the tumor and the pituitary gland in the sella turcica. Gross total removal of the tumor was performed through the orbitozygomatic approach followed by stereotactic radiosurgery. The oculomotor nerve paresis was resolved. Histological examination revealed an adenoma positive for ACTH. Ectopic pituitary adenoma occurs mostly in the sphenoid sinus or the suprasellar region. This extremely rare case of ectopic macroadenoma in the cavernous sinus manifested as oculomotor nerve paresis without signs of Cushing's syndrome.

A 57-year-old man was admitted with headache, vomiting, and bloody sputum. We diagnosed large cell lung cancer T4N2M1 (pituitary metastasis), Stage IV. When hospitalized, low values of cortisol and hyponatremia were found. A hormone stimulation test was performed, because we suspected hypopituitarism. The reaction of adrenocorticotropic hormone (ACTH) to the corticotropin-releasing hormone (CRH) loading test was good, but the reaction of serum cortisol was minimal. After corticosteroid administration, his serum sodium normalized. Limited ACTH reserve according to insufficient pituitary function was suggested as a cause of the hyponatremia. He received gamma-knife therapy, however his pituitary gland tumor did not decrease in size. Clinical symptoms such as visual field disturbance, oculomotor paresis, and visual impairment progressed, and he died about 5 months later. We report a case of hyponatremia in a patient with pituitary metastasis of lung cancer, as it is comparatively rare.
