PET‐CT using 18F‐FDG is employed for detecting brown adipose tissue (BAT) in humans. Alternative methods are needed because of the radiation and cost of PET‐CT imaging. The aim was to evaluate the accuracy of infrared thermography (IRT) in detecting human BAT benchmarked to PET‐CT imaging. Seventeen individuals underwent a total of 29 PET‐CT scans, 12 of whom were studied twice, after 2 h of cold stimulation at 19°C, in parallel with measurement of skin temperatures overlying the supraclavicular (SCV) fossa and the lateral upper chest (control), before and after cold stimulation. Of the 29 scans, 20 were BAT positive after cold stimulation. The mean left SCV temperature tended to be higher in the BAT‐positive group before and during cooling. It was significantly higher (P =0.04) than the temperature of the control area, which fell significantly during cooling in the BAT‐positive (−1.2 ± 0.3°C, P =0.002) but not in the negative (−0.2 ± 0.4°C) group. The temperature difference (Δtemp) between left SCV and chest increased during cooling in the BAT‐positive (1.2 ± 0.2 to 2.0 ± 0.3°C, P <0.002) but not in the negative group (0.6 ± 0.1 to 0.7 ± 0.1°C). A Δtemp of 0.9°C conferred a positive predictive value of 85% for SCV BAT, superior to that of SCV temperature. The findings were similar on the right. In conclusion, the Δtemp is significantly and consistently greater in BAT‐positive subjects. The Δtemp quantified by IRT after 2‐h cooling shows promise as a noninvasive convenient technique for studying SCV BAT function.

BMN is a rare clinicopathologic entity separate from AVN and has a distinctive MRI appearance. As MRI comes to play an increasingly important role in the evaluation of bone marrow disease, BMN is likely to be more frequently encountered. Awareness of BMN and its MRI appearance and appreciation of the frequent association between BMN and underlying malignancy may assist in the early diagnosis of BMN and initiate an intensive search for occult malignancy.

A 60 year old lady was referred to the Princess Alexandra Hospital (Brisbane, Queensland, Australia) tertiary Otolaryngology, Head and Neck Unit from a peripheral hospital for investigation and management of a tumour at the base of the tongue. Biopsy of the tumour revealed it to be an epithelial-myoepithelial carcinoma of the base of the tongue. This is an extremely rare tumour in this location with only 2 other case reports in the world literature: the patients were treated with chemo-radiotherapy and surgery respectively. Our patient was made aware of the world literature and was able to make a fully informed decision on her choice of treatment modality and was treated with radiotherapy. Increasingly journals are limiting publication of case reports to "world firsts" only. We present a case where such a policy would have denied patient choice and possibly led to detrimental treatment.We review the world literature of tongue base epithelial-myoepithelial carcinoma of the tongue.

F-FDG PET/MRI appears promising as an adjunct or alternative to PET/CT for quantitative evaluation in oncology, independent of body region and tumor type, across a wide range of SUVs.
