Peritoneoscintigraphy in detection of improper placement of peritoneal catheter into bowel lumen prior to chromic phosphate P-32 therapy. A case report

Radionuclide peritoneoscintigraphy has been used prior to chromic phosphate P-32 (P-32CP) intraperitoneal therapy to assure proper placement of the catheter in the peritoneal cavity, to exclude loculation, and to predict inadequate distribution of P-32CP. This is a case report of the detection of a peritoneal catheter improperly placed into the bowel lumen by pretherapy radionuclide peritoneoscintigraphy, and this case demonstrates the distinguishing characteristics of the radiocolloid distribution secondary to an intraluminal injection relative to an intraperitoneal injection.

Diffuse Radioiodine Lung Uptake in Miliary Thyroid Carcinoma Metastases

A diffuse pattern of homogeneous tracer uptake is seen by 1-131 scintigraphy in a patient with widespread miliary lung metastases due to papillary thyroid carcinoma. This case report emphasizes the need to include metastatic thyroid carcinoma in the differential diagnosis of miliary lung nodules.
