Graded compression sonography of abdominal neoplasms mimicking acute appendicitis

Gastrointestinal Radiology, 1992
Over a 3-year period nine patients (mean age of 43 years) with acute abdominal pain and unsuspected abdominal neoplasms were referred for graded compression sonography to rule out appendicitis. Six of the nine patients had right lower quadrant neoplasms involving the cecum, terminal ileum, iliacus muscle, or iliac lymph nodes.

Upper Abdominal Neoplasms: An Introduction and Selected References

Ultrastructural Pathology, 1991
The organs in the upper half of the abdominal cavity can give rise to a highly heterogeneous collection of neoplasms that encompasses a broad spectrum of clinical features, light microscopic appearances, immunostaining properties, and fine structure. Because of the anatomic proximity of the viscera in this region, the differential diagnosis of an upper

Eliminating Unenhanced CT When Evaluating Abdominal Neoplasms in Children

American Journal of Roentgenology, 2007
The purpose of our study was to evaluate a CT protocol that eliminates the unenhanced phase for imaging pediatric abdominal neoplasms.We retrospectively performed a case series study of all the abdominal CT scans on children and adolescents found in our archives. Two radiologists separately evaluated each CT scan twice. The radiologists were separately

Actinomycosis mimicking abdominal neoplasm. Case report.

Acta chirurgica Scandinavica, 1988
In a patient with a 6-month history of nonspecific abdominal complaints, preoperative examination indicated malignant disease involving the right ovary, rectum and sigmoid, but laparotomy revealed abdominal actinomycosis. Removal of the ovary and low anterior colonic resection followed by penicillin treatment gave a good result.

Multiple synchronous primary intra-abdominal neoplasms.

Journal of the National Medical Association, 1990
Multiple synchronous primary intra-abdominal neoplasms involving more than one organ system are rare, particularly if the appendix is involved. We report a patient with synchronous primary lesions in the colon, appendix, and the kidney. We also discuss the incidence of this entity with respect to sex and age, the organs most often involved in instances
