Given the crucial role of imaging in HCC diagnosis, LI-RADS CT/MRI was developed to standardize the imaging interpretation and reporting of HCC in patients at risk for HCC and categorize hepatic observations on an ordinal scale according to the likelihood of HCC. LI-RADS has since been expanded to include 5 algorithms: LI-RADS US Surveillance, contrast-enhanced US (CEUS) LI-RADS, LI-RADS CT/MRI, and LI-RADS Treatment Response Assessment. LI-RADS has been adopted broadly in North America, however with less ubiquitous adoption outside of North America.

- Brown tumors are rare bone lesions linked to hyperparathyroidism, often mistaken for multiple myeloma or metastatic cancer on imaging scans.
- A 45-year-old woman with hip pain had imaging that revealed numerous suspicious lesions, initially pointing toward serious conditions but eventually diagnosed as brown tumors after additional tests.
- This report aims to clarify the characteristics of brown tumors and how to distinguish them from similar conditions like multiple myeloma.
Wandering liver (WL) is an exceptionally rare anatomical variant, scarcely described in the medical literature. This condition is characterized by hypermobility of the liver within the abdominal cavity, resulting from the weakening, laxity, or absence of the liver's suspensory ligaments. This case report describes a 28-year-old male patient with a history of Sashi-Pena syndrome who presented with chronic, nonspecific abdominal pain, in which cross-sectional imaging incidentally revealed WL.

- The CheckMate-743 trial showed that nivolumab plus ipilimumab improves overall survival in patients with unresectable pleural mesothelioma compared to chemotherapy, but lacked representation of Latin American patients.
- A retrospective study evaluated this treatment's effectiveness and safety in 96 LATAM patients, focusing on their demographic and clinical characteristics, with a median follow-up of 24.1 months.
- Results indicated median progression-free survival of 8 months and overall survival of 22 months, confirming treatment benefits similar to other findings, with manageable adverse events reported.
This study aimed to evaluate the effect of nano-encapsulation of four essential amino acids (AA), threonine, methionine, tryptophan, and lysine on in vitro ruminal total gas, methane, carbon monoxide, and hydrogen sulfide production as well as the rumen fermentation profile in cattle. The highest (P < 0.001) rate and asymptotic gas production after 48 h of incubation was observed in the diets that had threonine, followed by lysine, methionine, and tryptophan.
