Frecuencia de malignidad en incidentalomas tiroideos detectados con tomografía por emisión de positrones/ tomografía computada (PET/CT) con F18-FDG de cuerpo entero DaviD LaDrón De guevara h. 1 , cLauDia munizaga m. a , naTaLia garcía s. a , caroLina LeTeLier B. 2 , aLex wash F. 1 Frequency of malignancy in thyroid incidentalomas detected by whole body 18F-FDg PEt/Ct Background: Thyroid incidentalomas detected by 18 F-Fludeoxyglucose (FDG) PET/CT are defined as an incidental and unexpected thyroid focus present in a patient studied for a non-thyroid disease. Aim: To assess the frequency of malignancy of nodular thyroid incidentalomas, and their association with 18 F-FDG avidity (standard uptake value (SUV) max). Material and Methods: Whole body PET/CT performed from December 2008 to December 2017 were reviewed selecting those that showed nodular thyroid foci. Glands with diffuse increased uptake were excluded. Thyroid ultrasonography and fine-needle aspiration cytology (FNAC) performed after PET/CT were reviewed. Bethesda score and SUVmax were correlated. Results: Of 5,100 whole body 18F-FDG PET/CT, 119 showed a thyroid nodular uptake (2.3%). Forty eight percent of these patients were studied with FNAC or surgery, 50% of which (29/58) were confirmed as malignant. Benign nodules showed significantly lower 18 F-FDG uptake (n = 20,

Endometriosis is a chronic and recurrent gynecological disorder that affects women of childbearing age; it may be manifested by infertility or chronic pelvic pain. Evaluation of this disease by clinical examination and ultrasound scan is usually of limited value. With the new advances in technology, MRI has proved to be highly helpful in the assessment of endometriosis, both for diagnosis and for evaluation of its extent. This dysfunction may adversely affect the organs of the reproductive system as well as gastrointestinal and genitourinary systems. Given MRI capability of tissue characterization and high contrast resolution, it is recommended as first-line technique in the evaluation of this condition.

. Las causas prehepáticas se deberían en su mayoría a trombosis de la vena porta, de sus ramas o peri sinusoidales 1,2 . Secundario a esto último se producirían cambios en la arquitectura hepática, consistentes en transformación nodular, conocida como hiperplasia nodular regenerativa (HNR) 1,2 . La HNR se caracteriza por transformación difusa del parénquima hepático en pequeños nódulos regenerativos con ausencia o mínima fibrosis 4,5 . Esta patología puede ser secundaria a tóxicos, fármacos, trastornos reumatológicos y hemato-oncológicos, los que estarían asociados a alteraciones sistémi-cas, tales como artritis reumatoide, poliarteritis nodosa, lupus eritematoso sistémico, policitemia vera, linfoma de Hodgkin y no Hodgkin, y drogas 4 . A pesar de que existen diversos factores que causan HNR, esta es una condición infrecuente, generalmente asintomática que se descubre incidentalmente 6 , motivo por el cual se presenta el caso clínico y se discute su eventual patogenia.
