Infantile hepatic hemangioendothelioma with subsequent malignant degeneration.

A 4 year old child was seen because of an enlarging epigastric mass and a rapidly falling hematocrit 31/2 years following steroid treatment for multiple hepatic hemangioendotheliomas. Technetium 99m sulfur colloid liver scan and hepatic angiography confirmed the presence of a large, vascular mass involving the left lobe of the liver. A left hepatic lobectomy was performed and histopathology showed angiosarcoma. As children with hemangioendotheliomas of the liver begin to survive for longer periods of time, surveillance for the possible development of neoplastic disease is recommended.

Xeroradiographic evaluation of obstructive lesions of the larynx and trachea.

Xeroradiography is a useful technique to evaluate the larynx and trachea for masses, granulation tissue, and, in general, to separate normal from abnormal morphology. Because of the edge enhancement effect, there is more information on the xeroradiograph than on the conventional radiograph, but the radiation exposure is 8-10 times greater. Thus, xeroradiography should be reserved for the evaluation of the airway in a child with respiratory difficulty where conventional imaging modalities have been unsuccessful.

Bladder calcification in the prune-belly syndrome.

Calcification of the bladder wall is described in two neonates with the prune-belly syndrome. The radiological and pathological findings are discussed and four additional cases are reviewed.

Diagnostic imaging in pediatric emergencies.

Evaluation of pediatric emergencies by diagnostic imaging technics can involve both invasive and noninvasive procedures. Nuclear medicine, conventional radiography, ultrasound, computerized axial tomography, and xeroradiography are the major nonangiographic diagnostic technics available for patient evaluation. Appropriate decisions regarding choice of these imagining technics can be made only if the advantages and limitations of each are known. We will emphasize the use of computerized axial tomography, nuclear medicine, xeroradiography, and ultrsound in the evaluation of emergencies in the pediatric age group. Basic principles with specific reference to clinical disorders will be presented. Since the radiologist is the primary consultant with regard to diagnostic imaging, his knowledge of these modalities can greatly influence patient care and clinical results.

Idiopathic arterial calcification of infancy.

Idiopathic arterial calcification of infancy is an uncommon disease of unknown etiology, characterized by calcification along the internal elastic membrane and intimal proliferation of almost all the arteries of the body. When the diagnosis is made premortem, it is usually done by radiographic demonstration of arterial calcification. Because of its edge enhancement effect, xeroradiography should be useful in detecting the soft tissue calcifications of this disease.

Angiography of the hemophilic joint.

Angiography in the hemophilic patient is a safe and reliable procedure for recognition of surgically treatable vascular abnormalities. When untreated, these abnormalities can cause repeated bleeding and progressive joint destruction.

Hemophilia and the female: considerations for the radiologist.

Hemophilia A and B are commonly considered male diseases because of their X-linked recessive inheritance, but clinical hemophilia is occasionally seen in females. This may represent an extreme example of the Lyon hypothesis in which a heterozygous female has only the one X chromosome bearing the aberrant gene in the active state.

Radiolographic exhibits in gross anatomy.

The discipline radiology is well suited to teach anatomy to first-year medial students. A series of exhibits of radiographic anatomy in the dissection laboratory, in conjuction with small group teaching sessions, serves this purpose well. Such displays are readily constructed from materials available in most radiology departments and are easily reproduced.

The radiological features of Histoplasma pericarditis.

The radiographic features of pericarditis due to Histoplasma capsulatum are described in 5 children. This diagnosis is suggested when enlargement of the cardiac silhouette is associated with pneumonia, parenchymal nodules or adenopathy. These findings are particularly significant if the patient lives or has lived in an area which is endemic for histoplasmosis. While pleural effusion is rare in primary histoplasmosis, it is frequently present in patients with histoplasma pericarditis.

Detergent enema: a cause of caustic colitis.

A 5-year-old boy developed acute colitis followed by stricture formation as a result of a detergent enema. The acute phase of the caustic induced colitis was reproduced in the dog and the rat using full strength and diluted detergent enemas. The severity of the experimental colitis was shown to be directly related to the concentration of the detergent.

Pancreatic pseudocyst of the mediastinum.

The mediassinum is a relatively uncommon site for a pancreatic pseudocyst. Two such cases are presented, along with a review of 14 additional cases from the English literature. In most cases the pseudocyst is located in the posterior mediastinum, with entry to the mediastinum via the aortic or esophageal hiatus. The most common presenting symptoms are chest or abdominal pain and dyspnea. Displacement of the esophagus and stomach anteriorly and to the left on the upper gastrointestinal series and an associated mediastinal mass are the most helpful radiographic manifestations.
