Bronchopulmonary foregut malformations. A unifying etiological concept.

Two cases of congenital bronchopulmonary foregut malformation are reported and another 27 cases reviewed and the findings analyzed. The left lower lobe and the entire right lung are the most common locations of pulmonary involvement. The distal portion of the esophagus or cardioesophageal junction was the most common site of communication (83%). The majority of the patients (60%) presented in the first eight months of life, and the incidence in females was nearly twice that in males. Chronic cough, recurrent pneumonias and respiratory distress were the most common clinical findings, whereas two patients were totally asymptomatic. The esophagogram was the single most useful diagnostic procedure (82%). The microscopic structure of the congenital fistula resembled esophagus, bronchus or both. Surgical treatment was curative in most instances. Sime deaths occurred prior to corrective surgery, whereas the postoperative deaths in most instances were related to severe associated congenital anomalies. We believe a common embryologic pathogenesis leads to the formation of a variety of bronchopulmonary foregut malformations. These bronchopulmonary foregut malformations include intralobar and extralobar sequestrations, pulmonary sequestration with patent, or involuted--partial or complete--gastroesophageal communication, esophageal or gastric diverticula, and esophageal or bronchogenic duplication cysts.

Computed tomographic scanning and the lumbar spine. Part II: Clinical considerations.

With the advent of computed tomography of the lumbar spine, the theories of a small number of pioneering physicians regarding the pathologic sequela of degenerative disc disease and the entities of central and lateral spinal stenosis have been translated into objective determinations which can now be observed by all. CT scanning has provided clinicians with a better appreciation of the diagnostic limitations of myelography and of the pathologic sequela of hemilaminectomy, dorsal-lateral fusion, and discectomy itself. Since the identification by CT scanning of the loss of disc volume, leading to lateral nerve entrapment and nerve compression resulting from fusion overgrowth, it has become clear that our present modes of therapy require comprehensive reevaluation. Because of the findings of CT scanning, dorsal-lateral fusion now appears to have a much reduced role in the treatment of degenerative disc disease and spinal stenosis. In an era in which unnecessary surgery is a matter of concern, CT scanning is an important means of ensuring that surgery will be undertaken only after thorough pathologic conditions.

Intraspinal abnormalities and congenital spine deformities: a radiographic and MRI study.

Forty-two patients with congenital spinal deformity were studied by magnetic resonance imaging (MRI). Sixteen patients had intraspinal abnormalities consisting of a tethered cord in 10, diastematomyelia in four, diplomyelia in three, syringomyelia in four, a low lying conus in three, and a teratoma of the sacrum in one patient. In seven patients, intraspinal anomalies were suspected based on routine spinal radiographs and physical findings. We recommend MRI in patients undergoing spinal stabilization procedures and in all patients with lumbosacral kyphosis and those with pain, neurologic findings, or cutaneous hairy patch.
