Thus far, their study is one of the largest on the interesting topic of lymphoscintigraphy findings in lipedema patients and the authors should be commended in this regard.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">1</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">However, in my opinion the interpretation of the lymphoscintigraphy images in their study is incomplete. Most studies use a semi-quantitative approach using the ratio of inguinal nodes to injection site uptake. This semi-quantitative analysis provides a reproducible way of image interpretation and all studies reported lymphatic drainage alteration in lipedema patients. However compared to lymphedema patients, the impairment is less severe. On the other hand, Forner-Cordero et al. used a semi-quantitative analysis which is ambiguous. How was scoring done for inguinal uptake? Did they use an area such as injection site or liver for comparison of inguinal uptake?</p><p id="par0015" class="elsevierStylePara elsevierViewall">They concluded that due to “frequent alterations in the patients with lipedema, the presence of findings does not discount a diagnosis of lipedema”. As no robust semi-quantitative index (such as inguinal to injection site ratio) is given, the conclusion seems incomplete as previous studies showed that despite lymphatic drainage compromise in lipedema, semi-quantitative indices can provide a good differentiation between lipedema and lymphedema.<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">2–4</span></a></p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "NotaPie" => array:1 [ 0 => array:2 [ "etiqueta" => "☆" "nota" => "<p class="elsevierStyleNotepara" id="npar0005">Please cite this article as: Sadeghi R.
