A new case of TEMPI syndrome.

We present an interesting case of a woman with new onset hypertension and abdominal fullness who was found to have huge bilateral perinephric fluid collections. Extensive workup revealed that she had secondary polycythemia, extensive truncal and proximal extremities telangiectasia and IgA-lambda monoclonal gammopathy of underdetermined significance. We believe that this is one of the rare cases consistent with the recently described TEMPI syndrome.

Is there a common SUV threshold in oncological FDG PET/CT, at least for some common indications? A retrospective study.

Purpose: We retrospectively compared the maximum standard uptake value (SUVmax) of FDG PET in four different sites to evaluate whether a common diagnostic SUVmax threshold may exist in these tumor locations. We further postulate that the SUVmax thresholds are higher in thoracic lesions than in extrathoracic lesions.

Material And Methods: N = 143 patients in four subgroups underwent a FDG PET/CT: a) 42 patients for solitary pulmonary nodules (SPNs) characterization with b) respective mediastinal lymph nodes (LNs), c) 65 patients for LN staging of head and neck cancer, and d) 36 cancer patients diagnosed with adrenal lesions.

Comparison between malignant and benign abdominal lymph nodes on diffusion-weighted imaging.

Rationale And Objectives: The purpose of this study is to review the apparent diffusion coefficient (ADC) values of benign and metastatic abdominal lymph nodes on diffusion-weighted imaging (DWI).

Materials And Methods: Twenty-eight patients with a total of 40 benign (20 patients) and 16 malignant (8 patients) lymph nodes who underwent DWI MRI of the abdomen (b = 0.600) were enrolled in the study.
