Total myelography in the evaluation of lumbar discs. With the presentation of three cases of thoracic neoplasms simulating nerve root lesions.

It has been our practice to perform total myelography in all cases of lumbar disc disease including the various syndromes of spinal stenosis, because experience has indicated that myelographic abnormalities in the cervical and thoracic areas could have clinical importance despite the presence of gross changes in the lumbar region. Failure to establish a definite diagnosis by restricted lumbar myelography makes it mandatory to evaluate all levels of the spinal axis. Recently, 3 patients with thoracic spinal cord tumors presented with primary signs and symptoms of lumbar spine disorders. Evidence of spinal cord disease was minimal and could be readily overlooked. Total myelography disclosed varying degrees of lumbar spinal pathology, but also showed evidence of lesions in the thoracic region. One proved to be an intramedullary astrocytoma of the spinal cord, and two were schwannomas. The symptoms of low-back pain and lumbar radiculopathy improved after excision of the schwannomas and following x-ray therapy and chemotherapy in the patient with the intramedullary neoplasm.

Pitfalls in the plain film evaluation of the thoracic aorta: the mimicry of aneurysms and adjacent masses and the value of aortography. Part I. Transverse aortic arch.

In five instances, transverse aortic arch aneurysms were found that had initially, clinically and radiographically, mimicked thoracic neoplasms. Transverse aortic arch aneurysms display a wide spectrum of presentation: they may be asymptomatic, or they may cause symptoms secondary to esophageal, bronchial, vascular, or neural compression within the mediastinum and so mimic neoplasms. Conventional radiography in four projections and tomography are important components of the diagnostic evaluation of middle mediastinal masses. However, because plain film analysis is unable confidently to distinguish selected uncalcified aortic arch aneurysms from neoplasms, thoracic aortography is essential to the diagnosis.

Angiographic differentiation of thoracic aneurysms and neoplasms.

The distinction between nondissecting aneuryms of the thoracic aorta and thoracic neoplasms may be difficult. The aortographic findings associated with aneurysms may be subtle. However, when the aortogram is properly performed and interpreted and the findings correlated with the plain chest roentgenograms the distinction between aneurysms and neoplasms may be made consistently. The thoracic aortogram should be filmed in at least 2 projections and abdominal aortography and ultrasonography should be performed. With aneurysms the aortographic signs include widening (often slight) of the aortic lumen, thickening of the aortic wall, small ulcer-like collections of contrast and non-filling of regional intercostal arteries. With neoplasms none of these radiological features is to be anticipated, while the aorta will be normal, displaced or narrowed.

The thorax as the initial site for systemic relapse in malignant melanoma: a prospective survey of 324 patients.

Thirteen of 324 patients with malignant melanoma followed during a 24 month period experienced dissemination. The thorax was the initial site for relapse in 12, all of whom were asymptomatic. Ten gave no evidence of extrathoracic disease. Retrospective analysis of previous x-rays originally interpreted as negative revealed metastases in 33%. Life table analysis demonstrated a significantly longer survival for the subset with isolated intrathoracic metastases treated surgically than for their counterparts with metastases no longer amenable to surgery and treated by other modalities. We conclude that the thorax is the site of predilection for initial systemic relapse in malignant melanoma, that detection of early, surgically resectable metastases correlates with longer patient survival, and that routine chest roentgenography is inadequate in reliably uncovering such early disease. These data suggest the potential value of more vigorous radiographic surveillance (with either computed tomography or conventional full lung tomography) in patients at high risk for relapse.

Whole-body nuclear magnetic resonance scanning: n.m.r. studies of tumour cells.

A technique, field-foxusing nuclear magnetic resonance (n.m.r.) spectroscopy (FONAR), is described for doing n.m.r. scans in large samples. The method utilizes a shaped d.c. magnetic field that confines the n.m.r. signal-producing region of the sample to a small volume called the resonance aperture. The aperture contains the required values of the Ho field to fully bracket the band of the r.f. pulse. The magnet system and r.f. pick-up coil that achieved the first human n.m.r. scan are discussed.

Tumorous phosphaturic osteomalacia. Report of a case associated with multiple hemangiomas of bone.

A case of osteomalacia associated with hypophosphatemia, decreased tubular reabsorption of phosphorus, hyperphosphaturia and renal glycosuria with associated bone pain and myopathy is presented. The patient was found to have multiple osteolytic lesions of bone which, on biopsy, proved to be sclerosing hemangiomas of bone. Treatment with oral phosphate and vitamin D effected a diminution in his symptoms of bone pain and muscular weakness. The literature on hypophosphatemic phosphaturic osteomalacia associated with mesenchymal tumors is reviewed. It has been suggested that certain mesenchymal tumors elaborate a yet to be identified humoral substance which decreased synthesis of 1 alpha, 25-dihydroxycholecalciferol causing decreased tubular reabsorption of phosphorus, hyperphosphaturia, hypophosphatemic osteomalacia and hypophosphatemic myopathy.

Computed tomographic scanning in children.

Computed tomographic scanning (CT) has been effectively utilized in evaluating the pediatric patient. Our experience with CT of the chest and abdomen in 19 patients has been described. The advantages offered by CT include: a unique anatomic display, the lack of morbidity, and an acceptable radiation dosage. Few technical disadvantages exist. Further application of this unique technique can be predicted.

Computerized tomography in the assessment of diseases of the thorax.

Many of the diseases of the chest wall, heart, mediastinum, pleura and lungs can be successfully imaged by computerized tomography. Radiation therapy ports can be calculated and transcutaneous biopsies monitored. This paper deals with the many uses that we have had for computerized tomography in assessing diseases within the chest and thorax.

Ganglioneuroma, heterochromia iridis, and Horner's syndrome.

A child with mediastinal and supraclavicular ganglioneuroma, heterochromia iridis, and Horner's syndrome is described. The authors postulate that the thoracic neoplasm originated as a congenital neuroblastoma with metastasis to the supraclavicular lymph nodes and subsequent benign transformation, and that the ocular abnormalities resulted from sympathetic ganglion injury by the tumor in infancy. This seems to be the first published report of such ocular abnormalities associated with mediastinal ganglioneuroma.

Pulmonary embolism associated with hemolymphangioma of lower extremity.

We present a case of major pulmonary embolization from a hemolymphangiomatous malformation of the loin and lower extremity. Treatment was with a low-dose infusion of urokinase for a short period directly into the pulmonary artery, and dramatic clinical improvement was noted. Prolonged maintenance therapy was with a low dose of heparin.
