Peritoneal localization of gallium-67.

Diffuse abdominal localization of 67Ga was found in two patients with peritonitis; one due to M. tuberculosis, and the other presumably pyogenic, following multiple perforations of the small bowel due to necrotizing ulcerating enteritis. After 7 months of antituberculous treatment of the first patient, a normal gallium distribution was noted. It is suggested that gallium scanning may be useful in the diagnosis of peritonitis and perhaps of other serosal infections.
