[ 1 ] - False positive 18F-FDG PET/CT due to active varicella zoster infection in a Hodgkin’s lymphoma patient
We report a case of Hodgkin lymphoma (classic type) referred for response assessment after two cycles of chemotherapy with ABVD regiment. The F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET/CT) showed hypermetabolic cutaneous and subcutaneous lesions with a linear pattern in the left arm with significant F-18 fluorodeoxyglucose positron accumulation in associate with left axi...
[ 2 ] - Detection of solitary bone metastasis by 99mTc-octreotide scintigraphy in a patient with Hurthle cell carcinoma: A case report
A 75-year-old male patient with non-avid radioiodine Hurthle cell carcinoma was evaluated by 99m Tc- octreotide scintigraphy, in order to find possible metastatic lesions. A bony metastatic lesion was detected by this procedure which was confirmed by histopathology.99mTc-octreotide scintigraphy is a precise and cost-effective imaging modality for detection of non-iodine av...
[ 3 ] - Giant enostosis of spine with increased uptake on planar and SPECT views of bone scan
An enostosis or bone island is a benign bony lesion that is almost diagnosed based on clinical and radiologic defining characteristics. One of the known diagnostic procedures in the evaluation of enostosis is bone scintigraphy. Generally, we don’t expect to see increased uptake by enostosis in the bone scan. Herein we present a 52-year-old lady who was suffering from chronic low back pain that ...
[ 4 ] - Radioiodine avid adenomatous colon polyp in a post-treatment whole body radioiodine scan
A 47 year old female with papillary thyroid carcinoma was referred to our department for post-treatment whole body iodine scanning. The acquired images revealed a focal zone of intense radiotracer uptake in the right lower quadrant of the abdomen. SPECT/CT fused slices showed a focal zone of the radioiodine (131I) uptake in the right colon wall. Colonoscopy revealed a pedunculated po...
