Imaging of normal anatomy and anomalies of the brain.

Magnetic resonance imaging permits better delineation of many anatomic structures not resolved with other imaging modalities and, by permitting the behavior of these structures to be observed at different pulse sequences, allows their tissues to be characterized. The literature of the year 1990 to 1991 includes many descriptive reports of normal anatomy, some of which are accompanied by explanations for the MR signal appearance. Familiarity with normal central nervous system structures and with normal MR signal characteristics is essential to avoid mistaking them for pathologic variants.

Flow, radiofrequency pulse sequences, and gradient magnetic fields: basic interactions and adaptations to angiographic imaging.

The basic process of MRI consists of two essential, relatively independent components: (1) excitation in the form of a radiofrequency pulse sequence, and (2) signal sampling and localization, that is, forming the MR image through the use of field gradients. The presence of motion (blood flow) during either excitation or sampling results in two types of corresponding effects: (1) time-of-flight effects, and (2) spin phase phenomena. These effects can be manipulated through the use of special coils, pulse sequences, gradients, and postprocessing techniques to provide angiographic images in which simple motion provides the basis for contrast.

Tuberculous empyema necessitatis. Computed tomography findings.

Two patients who presented with an anterior chest wall mass were evaluated by computed tomography (CT) scan and were found to have an associated thick-walled pleural collection, consistent with empyema necessitatis. In view of the increasing incidence of pulmonary and extrapulmonary Mycobacterium tuberculosis infection, the entity of tuberculous empyema necessitatis should be strongly considered when the described CT findings are present.

Gastrointestinal myoelectric activity in an infant with congenital idiopathic motility disorder.

We investigated myoelectric activity in an 8-month-old male who presented with a perinatal bowel obstruction, duodenal band, congenital short small intestine, and persistent feeding intolerance. Serosal electrodes were surgically implanted on stomach, duodenum, and jejunum during Nissen fundoplication and ileostomy. A 5-cm ileal specimen was taken for in vitro studies. Spontaneous migrating myoelectric complexes (MMC) were present in stomach and small intestine. Bethanechol increased electrical response activity (ERA) in stomach and duodenum. Morphine induced intense ERA and distinct phase III activity. Pentagastrin infusion did not disrupt MMC cycling. Feeding disrupted MMC complex cycling 30-40 min after the meal. Metoclopramide before feeding delayed disruption of the MMC cycling after the feeding. Intermittent gastric arrhythmias were present after the fifth postoperative day. In vitro muscle strips showed spontaneous contractions and electrical control activity (ECA). Bethanechol, McNeil A-343, motilin, and cholecystokinin induced contractions, but pentagastrin had no effect. We conclude that in spite of a major clinical motility dysfunction, several of our findings were normal. The abnormalities include short MMC period, absence of disruption of MMC by pentagastrin, and gastric arrhythmias.

Incarcerated obturator hernia: case diagnosed at barium enema fluoroscopy.

Incarcerated obturator hernia is an uncommon entity that on occasion may produce specific radiographic findings and clinical signs (Howship-Romberg sign) that permit diagnosis prior to celiotomy. A case is reported in which the diagnosis was suggested when pain in the thigh was elicited during the course of a barium enema examination.

The contraindications for blind esophageal bouginage for coin ingestion in children.

Per oral bouginage of the esophagus for coin lodgement in children is a safe and simple mode of therapy. However, our experience with chronically ingested coins, multiple coins ingestion, and ingestion with preexisting esophageal pathology illustrate the potential hazards of such a practice. Intramural perforation, subacute mediastinitis, tracheoesophageal fistula, and long-term residual injury to the esophagus hallmark such cases. We believe that only acutely ingested coins, and only a single coin, can be treated safely by means of "blind" bouginage, provided that no preexisting esophageal disease is present.

Esophageal bougienage technique for coin ingestion in children.

An analysis was performed of 46 consecutive children who received esophageal bougienage for an ingested coin lodged in the esophagus. All patients met the following clinical criteria necessary for performance of this procedure: an acutely ingested single coin, radiographically localized in the esophagus; no previous history of an esophageal disease process, surgical procedure performed or foreign body removed; and no respiratory compromise upon physical examination. All coins were successfully advanced distally into the stomach after one pass of the bougie dilator. No complications were noted during or after performance of any procedure. Esophageal bougienage is a safe and effective method used to dislodge and pass an ingested coin from the esophagus when criteria for its performance are adhered to rigidly.

Steroids and bag and mask ventilation in the treatment of acute epiglottitis.

A non-instrumentation treatment protocol for acute epiglottitis that features the use of dexamethasone to reduce edema and positive pressure ventilation by bag and mark to support ventilation, if needed, has been used in 40 cases, 1974--1977, with no mortality. The presence of the airway specialist (pediatric surgeon) in the Intensive Care Unit with the patient further assured the airway. The importance of having a protocol in place that is workable for the specific local circumstances of each institution is emphasized.

Anatomic observations and etiologic and surgical considerations in choledochal cyst.

Twenty-five operative and postoperative cholangiograms in children with choledochal cysts indicated an intimate relationship between these cysts and anomalous pancreatico-biliary ductal junction. In all of these patients the distal main pancreatic duct (MPD) is excluded from the sphinctor of Oddi mechanism and free reflux of pancreatic juice up the biliary tree occurs. This leads to chronic cholangitis, which is presumed to be responsible for the formation of the choledochal cysts. Abrupt and intense exposure of the common bile duct (CBD) to pancreatic reflux may cause perforation and bile peritonitis. Long-standing exposure may induce malignant transformation in the choledochal cyst. Total cyst excision and separation of the biliary system from exposure to pancreatic reflux is suggested as the procedure of choice. Long-term results and metabolic and digestive consequences of this operation are yet to be determined.

Ectopic single ureter and severe renal dysplasia: an unusual presentation.

An ectopic single ureter in the male subject is a rare anomaly, which commonly drains a dysplastic kidney to the prostatic urethra or the seminal vesicle. The further the ureteral orifice is located from the trigone of the bladder, the more severe is the ipsilateral renal dysplasia. A case is described in which an ectopic ureter and ectopic and dysplastic kidney were found at the time of inguinal herniorrhaphy. The ureter was connected to the epididymis of the testicle. This is the most severe form of ureteral ectopia and it has not been reported previously.

Neonatal cystic choristoma in submandibular salivary gland simulating cystic hygroma.

A congenital cystic malformation occurred in the submandibular salivary gland of a neonate. The embryogenesis and differential diagnosis are discussed. Since it seems to be a product of endodermal heterotopic differentiation or entrapment of foregut epithelial rests in the submandibular gland, it is classified as a cystic choristoma.

Large branchiogenic cyst in a neonate producing upper airway obstruction.

We report on a large branchiogenic cyst in a neonate. The etiology of these cysts is assumed to be of branchial origin because of their communication with the pharynx and their intimate association with the thyroid and thymus glands. This report documents an additional occurrence of this rare lesion. Physicians are alerted to the fact that, should massive enlargements and compromise of the respiration be present, external decompression of these cysts is feasible.

Pleural dialysis in acute renal failure.

An 80 day old infant developed acute renal failure postoperatively after nephrectomy for Wilm's tumor. Pleural dialysis was utilized to control electrolyte imbalance of acute renal failure. Function of pleura as a dialyzing membrane was evaluated for the clearance of urea and creatinine.
