A case of pulmonary embolism associated with diabetes insipidus is reported in an 18-year-old male. The patient, who had been treated with DDAVP for diabetes insipidus and hydrocortisone for hypocorticism for two years after first operation for the removal of craniopharyngioma, was admitted with recurrence of that tumor. Diabetes insipidus immediately after second operation was controlled with intermittent drip infusion of a small amount of aqueous pitressin under monitorings of body weight hourly using a patient weighing system to keep the weight changes within +/- one kilogram. Serum and urine electrolytes levels, osmolarity, and free water clearance were also monitored every three hours to maintain water-electrolytes balances appropriately. Postoperative course had been uneventful except that CSF rhinorrhea occurred 7 days after operation. The patient was, then, kept in bed with horizontal plane to avoid further leakage of CSF. Two days later, he developed chest pain suddenly with tachypnea, tachycardia, and general cyanosis. The arterial-BGA showed PaO2 of 53.5mmHg and PaCO2 of 35.3mmHg in room air. The definite diagnosis of pulmonary embolism was made by technetium microaggregate lung perfusion scans and by pulmonary angiograms. The patient was treated with heparin, 15000IU/day, and urokinase, 720000IU/day. The symptoms due to pulmonary embolism had improved gradually within a couple of weeks. Recent articles have shown an unexpected high incidence of deep vein thrombosis and pulmonary embolism in neurosurgical patients associated with the elevation of blood coagulability. Brain tumors, especially suprasellar mass with hypothalamic dysfunction have been suggested to cause thromboembolic disorders frequently. The clinical course was described and factors causing pulmonary embolism on this patient was discussed.

Pulmonary embolism in childhood is a rare but under-diagnosed condition. We report four children aged 5 to 13 years presenting with pulmonary emboli, their primary diagnoses being craniopharyngioma, asthma, Crohn's Disease and Reye's syndrome. The diagnosis was supported by technetium micro aggregate lung perfusion scans in three of the children and in the fourth, the only child to die, by autopsy. Three of the children had markedly elevated plasma osmolalities, one as a result of his diabetes insipidus and two following hyperosmolar treatment for cerebral oedema. The child who died was found to have a femoral vein thrombosis but the sites of origin of emboli in the other children were not defined.

A 57-year-old man presented to our facility with the diagnosis of a suprasellar mass and died on the 2nd post-admission day from a massive pulmonary embolism. At autopsy, the mass was diagnosed as craniopharyngioma. This case report and review of the literature suggest an intimate relation between brain tumors and thromboembolic complications as evidenced by the high incidence of this association, the frequent occurrence of coagulopathies in patients with brain tumors, and the prevalence of tumors in the suprasellar location. The specific mechanisms that may be at play are reviewed.

A 63-year-old man developed bilateral peroneal nerve palsies after a craniotomy for a craniopharyngioma. It is believed that the primary etiology of the nerve palsies was intermittent pneumatic compression, which was used to prevent deep vein thrombosis and pulmonary embolism during the surgery. Physicians should take care to avoid compressing the fibula head when using pneumatic devices.

We describe a case of 65-year-old obese female patient with pulmonary embolism and life-threatening hypernatremia after removal of craniopharyngioma. On the 18th day after neurosurgical procedure, pulmonary embolism developed abruptly. Immediately after placement of inferior vena cava filter, surgical removal of the pulmonary thrombus was performed under cardiopulmonary bypass. Although mechanical ventilatory support and infusion of noradrenaline were required postoperatively, the trachea was extubated on the 10th postoperative day. Meanwhile, daily serum Na level increased gradually and reached 178 mEq x l(-1). We suspected that dehydration and pituitary dysfunction were mainly responsible for the hypernatremia. Human atrial natriuretic peptide (hANP) was infused from the 2nd to the 4th postoperative day, and her urinary Na excretion became increased and serum Na level became normal. After discontinuation of hANP, urinary Na excretion became decreased again and serum Na levels increased transiently. However, her consciousness level and cardiopulmonary condition improved and she was discharged from the ICU after twelve days of ICU stay. HANP may be useful for treatment of life-threatening hypernatremia.

The effectiveness and safety of fronto-basal interhemispheric approach in treating craniopharyngioma were evaluated. In this retrospective study, the safety and effectiveness of fronto-basal interhemispheric approach for surgical resection of craniopharyngioma in 20 patients was analyzed. Of the 20 patients, 12 were men and 8 were women, aged 15-65 years, with an average age of 42.5 years. The course of disease ranged from 1 to 36 months. The craniopharyngioma tumor was completely removed through surgical resection in 18 patients (90%) and partially removed in 2 patients. The pituitary stalk was preserved in 18 patients and 1 patient succumbed during the study period due to large area pulmonary embolism. In conclusion, fronto-basal interhemispheric approach provides better access to the tumor that grows in the sella-hypothalamus and anterior third ventricle region. Using this approach, tumors can be resected while preserving the vital structures such as the pituitary stalk and hypothalamus.
