Increased echogenicity of the spleen in benign and malignant disease.

Infiltration of the spleen in hematopoietic malignancy can produce diffusely increased parenchymal echo return on gray scale ultrasonography. In 13 patients with splenomegaly and an increased splenic echo pattern, nine had diagnoses of hematopoietic malignancy. Contrary to previous reports describing low-level echo return and increased anechoic conditions with infiltrating malignancy of the spleen, the patients in this report show that increased splenic echogenicity can be associated with malignant involvement.

Non-lymphoreticular cancer of the gastrointestinal tract in the young adult: general hospital experience.

A review of 39 cases of non-lymphoreticular cancer of the gastrointestinal (GI) tract in young adults (ages 18-40 years) compiled from the tumor registries of three general teaching hospitals during the years 1966-1976 is presented. Several aspects of their clinical presentation, diagnostic evaluation, and treatment are assessed. Several features are worthy of comment regarding this subgroup of cancer patients: unexplained anemia, evidence of GI tract blood loss, and weight loss are frequent findings, singly or in combination; delay in diagnosis of gastric malignancy may be occasioned due to response of abdominal complaints to nonspecific therapy such as antacids; and an unexpectedly high number of women were among the cancer group, especially among those with stomach and colorectal cancer.

Betwixt and between false positives and negatives.

The problem of inaccurate roentgen interpretation is complex and not completely understood. Moreover, it would seem that greater emphasis ought to be placed on appropriate physiological and psychological research to better understand this subject. Yet much has been learned about the mechanisms involved in image perception and some practical suggestions are available to in part reduce our observer error. Residency programs ought to include this subject in their overall training scheme so that diagnostic radiologists become aware of the human as well as technical factors present in roentgen interpretation.

Spontaneous resolution of colonic strictures caused by necrotizing enterocolitis: therapeutic implications.

Colonic strictures are now a well recognized complication in infants surviving necrotizing enterocolitis. We describe the clinical course of seven infants with colonic strictures after necrotizing enterocolitis. Only two demonstrated the finding of fixed fibrotic stricture described in the literature, while the remaining five showed atypical radiographic and pathologic features. Two of the five showed partial or spontaneous resolution of post-necrotizing enterocolitis colonic stenoses on follow-up barium enema studies. In three of four patients with colonic resections, the histopathologic examination revealed a surprising absence of irreversible fibrosis or cicatrix formation. Current surgical practice dictates elective resection of these narrowed colonic segments. The radiologic and pathologic findings in our series of patients suggest surgical resection may be unnecessary in selected cases.

Measurement of plasma contrast levels during excretory urography.

Ultraviolet spectrophotometry permits easy measurement of plasma levels of intravenously injected contrast media. The initial results are described from the determination of plasma methylglucamine iothalamate (Conray 60) levels during routine excretory urography in 10 normal patients. This simple procedure has many potential applications in the investigation of contrast media physiology.
