Diabetic patients with peripheral arterial disease frequently experience gangrene of the lower limbs. It has been suggested that a bone scan is useful in differentiating viable from nonviable tissues in patients with extensive peripheral gangrene and thus can help determine the appropriate level of amputation in such patients. We present a 68-year-old diabetic woman with right breast cancer, who was referred to our facility for a bone scan as part of her metastatic workup. Bone scan findings revealed absolute photon deficiency in the distal half of her left lower limb.
Purpose: Chilaiditi’s syndrome is a rare condition commonly diagnosed as an incidental radiological finding. The aim of this report is to show the role of SPECT-CT in this syndrome and state the functional and anatomical role of this hybrid imaging modality.
Materials and Methods: A case report.
Results: A 49-year-old female patient was referred for gallium-67 citrate for a possible
granulomatous myositis and underwent SPECT-CT of the abdomen to assess the area of decreased gallium uptake on planar images of the liver. The combined SPECT and CT modality demonstrated findings consistent with the clinical evidence of Chilaiditi’s syndrome. The anatomical part of this hybrid modality made it easier to evaluate the area of gallium lack of uptake which was due to air in the colon.
Conclusion: This case does not only show the role of SPECT-CT in this syndrome but also suggest that the use of such modality should be considered whenever available in the evaluation of patients in whom the localization of active disease becomes imperative.
Receptor targeted imaging using prostate specific membrane antigen (PSMA)-a labeled radioisotope currently plays a key role in prostate cancer imaging. This is due to the overexpression of PSMA, a type II Tran's membrane protein, in prostate cancer cells. caution in the interpretation of distant nodal uptake sites on 68 Ga-PSMA PET/CT imaging for the diagnosis and/or staging of prostate cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
