Two patients who had removal of seemingly benign pheochromocytomas had recurrences 10 and 14 years later despite normal catecholamine excretion for 7 and 9 years postoperatively. The first patient returned with a myocardial infarction and an apparently solitary recurrence; the second patient with a stroke and metastatic disease. Both patients had recurrence of hypertension and increased catecholamine excretion. They were given phenoxybenzamine and are doing satisfactorily 7 and 9 years after their recurrences. Such patients should be followed after surgery for 15 or more years for early detection of recurrences. Prompt therapy should reduce the risk of undesirable complications.

A 56 year old woman developed multiple metastases in the cerebrum and cerebellum, four years after cardiac intervention on a left atrial myxoma. The absence of stroke is noteworthy. Multiple high density lesions with contrast enhancement were seen by CT scan, suggesting metastatic neoplasms. Histological examination confirmed the diagnosis of metastases of cardiac myxoma. Only four cases were recorded in the literature.

Nutritional antioxidants support prostacyclin synthesis by preventing lipid hydroperoxide-mediated inhibition of prostacyclin synthetase. Recent preliminary clinical studies indicate that supplementary antioxidants exert antithrombotic effects in vivo that are most likely attributable to enhanced prostacyclin production. Optimal antioxidant nutrition may thus have preventive and therapeutic value for disorders in which inappropriate platelet aggregation plays an etiologic role, including MI, stroke, atherogenesis, pre-eclampsia, and the vascular complications of diabetes. In light of evidence that platelet aggregation encourages the implantation of hematogenous tumor metastases, supplemental antioxidants should also impede tumor dissemination--an effect which will be complemented by the immunostimulant actions of these nutrients. By exerting anticarcinogenic, immunostimulant and anti-metastatic effects, nutritional antioxidants should act to inhibit neoplasia at each stage of its development.

Hepatic resection for metastatic disease is reviewed in 30 patients (mean age 58.9 years). The primary site was the colorectum in 25; the other primary tumours were leiomyosarcoma, plasmacytoma, and adenocarcinoma (all of gastric origin), ocular melanoma and an unknown primary. Operative procedures included 7 wedge resections, 5 segmentectomies and 21 lobectomies (11 right, 4 extended right and 6 left). Major complications in seven patients included intraoperative hemorrhage in three, two of whom died, bile-duct injury in two, small-bowel infarction in one and cerebrovascular accident in one. Operative death rate was 6.7% (2 of 30). Thirteen patients were alive and free of disease a mean of 24 months after hepatic resection while 5 more were alive with disease at a mean of 36.9 months. Life-table analysis projected a 5-year survival of 50.3% for those with colorectal primaries, with no apparent difference in survival between patients with single (55.0%) and multiple (54.0%) metastases. Improved survival was projected for patients with metachronous (66.6%) versus synchronous (45.0%) tumours, primary Dukes' class A or B (66.1%) versus Dukes' class C (46.0%) tumours and those having wedge resection or segmentectomy (66.6%) versus lobectomy or extended lobectomy (48.0%). Hepatic resection for metastatic disease can be done with acceptable morbidity and mortality and the expectation of substantially prolonged survival particularly in patients with metachronous lesions or Dukes's A or B colorectal primary lesions.

Acute global aphasia without hemiparesis has been considered pathognomonic of embolic stroke. During 1 year, we encountered six patients with this syndrome. Two had multiple strokes, probably embolic. One had atrial fibrillation; at autopsy, there were metastases as well as multiple infarcts in the left hemisphere. One had a single large infarct in the territory of an anterior branch of the middle cerebral artery (MCA), one had subarachnoid hemorrhage of unknown origin, and one had a sylvian fissure hematoma with intraparenchymal extension from a ruptured MCA aneurysm. Nonembolic etiologies are therefore also possible and include conditions that bar anticoagulation.

The initial surgical management of neck metastases from head and neck cancer may be complicated if the tumor mass invades the carotid vessels. Acute carotid ligation is associated with a high stroke rate. Consequently preservation of flow to the internal carotid artery is desirable. We will describe two patients in whom preservation of flow was accomplished with the use of a saphenous vein bypass from the axillary artery to the internal carotid artery. The technique is described and has several advantages. First, it preserves flow to the internal carotid artery; second, it allows radical excision of tumor without compromising the margins of resection; and finally, at least one suture line and most of the graft are outside the field of radiation and remote from the wound closure. We believe that this technique is useful in the management of patients with disease that has metastasized to the neck.

We describe a woman with metastatic small cell carcinoma of the lung who presented with pituitary apoplexy and hyperprolactinemia. Within seventeen months she developed florid Cushing's syndrome with anasarca, hyperpigmentation, hypertension with marked hypercortisolemia (not suppressible with 8 mg dexamethasone), elevated serum ACTH, hypokalemic metabolic alkalosis, and multiple hepatic metastases. This picture suggested the presence of ectopic ACTH syndrome. She died 26 months after the episode of pituitary apoplexy. Primary small cell carcinoma of the lung was diagnosed post-mortem. Metastases were present in the left lung, regional lymph nodes, heart, liver, bone marrow, sphenoid bone, anterior pituitary and pituitary capsule. Posterior pituitary was normal. There was no evidence of pituitary hyperplasia, of adenoma or of primary pituitary carcinoma. The results suggest the presence of a primary ACTH-producing small cell carcinoma of the lung that metastasized to the parasellar sphenoid bone and then extended to the anterior pituitary and dura to mimic a primary intrasellar cause of pituitary apoplexy and Cushing's syndrome. The case demonstrates how difficult it may be to diagnose the etiology of Cushing's syndrome and it emphasizes a unique variation in the presentation of small cell carcinoma of the lung.

Based on provisional clinical diagnosis, the choice of computed cranial tomography (CCT) or radionuclide brain scan (RBS) was retrospectively evaluated. In 1,333 selected cases, 551 had CCT only, 560 had RBS only, and 222 had both. CCT was the clinician's preference in cases of dementia, hydrocephalus, hemorrhage, aneurysm, arteriovenous malformation (AVM), primary tumor, visual abnormality, coma, and multiple sclerosis. RBS was preferred in headache, syncope, seizure, transient ischemic attack (TIA), metastatic disease, and encephalitis. Neither procedure appeared preferable in cases of psychosis, psychiatric disease, cerebral vascular accident (CVA), and abscess. Thirty-eight percent of CCTs yielded abnormal findings, not necessarily correlated with the provisional diagnosis. Thirty percent of RBS showed positive findings, mostly related to vascular abnormalities. On the basis of the provisional clinical diagnosis, CCT was more frequently requested for probable structural changes and RBS for probable perfusion abnormalities.

A retrospective study of elderly patients admitted with subdural haematoma showed a greater incidence in men. Although a history of falls or head injury was obtained in about two thirds of the patients, the initial diagnosis of subdural haematoma was only made in about one fifth of the cases. In most patients the symptoms were attributed to a cerebrovascular accident or cerebral metastases. However, in those patients where the diagnosis was established at post mortem, it was not the principal cause of death. Only half the patients treated by surgery were well enough to return home, although less severely ill patients treated by medical methods or conservatively were all able to return home.

A 34-year-old male developed multiple intracranial and intraspinal metastases from an invasive ACTH secreting pituitary adenoma. He was initially admitted to our hospital complaining of visual loss 10 years ago, presenting a pituitary tumor with suprasellar extension. At first, transsphenoidal surgery was performed, and histological finding was pituitary apoplexy. He developed recurrence of the tumor 2 times. At the second, third and fourth operation, the histological finding was an ACTH secreting pituitary adenoma with atypia. Metastases within the central-nervous system of pituitary adenoma is a rare entity and only 21 cases have been published. A review of previously published cases follows.
