[Fracture of the sella turcica--a case report and review of the literature].

Abstract: The incidence of a fracture of the sella turcica is reported to be rare and the authors reported a case of a sellar fracture associated with several neurological and endocrinological complications. A 16-year-old boy was struck at the face and the forehead on the road in a motorcycle accident and was hospitalized in a confusional state. Neurological examinations showed dilatation of the both pupils, sluggish light reflex on both sides and bilateral oculomotor palsy but motor weakness or sensory disturbance was not present. On the tenth hospital day, he developed diabetes insipidus and endocrinological examinations disclosed the impairment of GH, LH and FSH reserves, too. Neuroradiological examinations disclosed fractures of bilateral frontal bones and fractures of the left optic canal and ethmoidal roof as well as a fracture of the sella turcica. On the 28th hospital day, he also developed CSF rhinorrhea and pneumocephalus. Surgical repair for the CSF rhinorrhea was performed. Fractures of the sella turcica were reviewed in 23 cases including our personal case and a special consideration regarding the mechanism of sellar fractures and their major complications was made. The authors stressed the early recognition of a fracture of the sella turcica in head injuries, which would suggest a severe hypothalamo-pituitary involvement or other neurological disorders.

A Case of Pheochromocytoma Originating from the Superior Cervical Sympathetic Ganglion

Abstract: Pheochromocytomas are functionally active tumors which occur most commonly in the adrenal medulla but which can also develop in an extra-adrenal site. Over 90% of pheochromocytomas including extra-adrenal tumors are located between the diaphragm and the pelvic floor. Only two previous reports of pheochromocytoma originating from the cervical sympathetic chain were found in the literature. A thrid case of pheochromocytoma originating from the cervical sympathetic chain is presented. The patient was a 18-year-old boy who was admitted to the Sapporo Medical College Hospital, because of attacks of palpitation, headache, generalized sweating and numbness in the four extremities during the past three years. Paroxysmal hypertention was noted and a high level of noradrenalin in plasma and urine was shown. The patient was diagnosed as having a pheochromocytoma. However, it was difficult to detect the tumor. A tumor, which was situated on the right side of the neck at the angle of the jaw became enlarged and palpable after one year. Selective angiography and CT were performed, and the tumor was removed. The tumor, which was 6×3.5×3.5 cm in size, had originated in the right superior cervical sympathetic ganglion. A pathological examination showed chromaffin paraganglioma or pheochromocytoma. The postoperative course was uneventful.
