Nonpalpable breast microcalcifications: frequency, management, and results of incisional biopsy.

In a series of 500 consecutive needle localizations, there were 165 biopsies for benign microcalcifications without a mass. An incisional biopsy was performed in 49 of these cases (30%). Follow-up mammograms were available for review in 39 of the cases. The average length of follow-up was 32 months. In no case did malignancy develop at the biopsy site. When an incisional biopsy is performed, careful follow-up mammography is an alternative to a repeated needle localization and biopsy in selected cases.

Recurrent appendicitis: reexamination of a controversial disease.

The existence of recurrent appendicitis as a true disease entity is still disputed. The controversy surrounding recurrent appendicitis is discussed. This disease is thought to represent repeated inflammation of a nonperforated appendix. Case material supporting this concept is presented. The barium enema can provide evidence of the diseased appendix.

"Step-off" vertebral body: Gaucher's disease versus sickle cell hemoglobinopathy.

Two patients with Gaucher's disease and radiographic findings in the spine similar to sickle cell hemoglobinopathy are reported, making a total of four known patients with Gaucher's disease who have these steplike vertebral endplate deformities. Serial films of a patient having Gaucher's disease compared with patients having sickle cell hemoglobinopathy suggest that different events lead to formation of the vertebral deformities. In Gaucher's disease, there is an initial collapse of the entire vertebral body with subsequent growth recovery peripherally. In sickle cell hemoglobinopathy, the endplate deformity is nontraumatic and is caused by an underlying growth arrest.

Abnormal left hilar height ratio.

This investigation establishes the usefulness of the hilar height ratio concept and reviews those disease processes that may become manifest by an abnormal left hilar height ratio. In the absence of lower lobe volume loss and extrapulmonary disease, an abnormal left hilar height ratio may reflect upper lobe emphysema.

Percutaneous localization of breast lesions: experience with the Frank Breast Biopsy Guide.

The advantages of a wire localization guide for nonpalpable breast lesions have been demonstrated in 16 patients. The hooked end will not move after placement when the external end is anchored by a strong clamp. The malleable wire permits post-insertion compression mammograms to be performed. With the wire left in situ, orientation of the biopsy specimen with post-localization mammograms can guide the surgeon if further resection is necessary.

Mediastinal lipomatosis. CT confirmation of a normal variant.

Mediastinal lipomatosis is a common benign cause of mediastinal widening. While it may be associated with exogenous obesity, steroid ingestion, or Cushing's syndrome, these factors often are not present. Evaluation of the mediastinum by CT should be the initial diagnostic study in the work-up of patients with abnormalities of the mediastinal contour; indeed, in many cases it can eliminate the need for other procedures.

Acute diverticulitis in the young adult.

Seven cases of acute diverticulitis in patients 35 years of age or younger are presented. This disease is not rare in young adults. There seems to be a higher incidence in males and an increased need for surgical intervention when younger individuals are affected. The barium enema is useful in confirming the diagnosis.
