Exploring Response to Immunotherapy in Non-Small Cell Lung Cancer Using Delta-Radiomics.

Delta-radiomics is a branch of radiomics in which features are confronted after time or after introducing an external factor (such as treatment with chemotherapy or radiotherapy) to extrapolate prognostic data or to monitor a certain condition. Immune checkpoint inhibitors (ICIs) are currently revolutionizing the treatment of non-small cell lung cancer (NSCLC); however, there are still many issues in defining the response to therapy. Contrast-enhanced CT scans of 33 NSCLC patients treated with ICIs were analyzed; altogether, 43 lung lesions were considered.

A very rare case of mycobacterium gordonae infection of the breast.

Mastitis is a common disease in women with both infectious and noninfectious causes. Most cases occur during lactation and are caused by Staphylococcus aureus and Streptococcus species; parasites and Mycobacteria have rarely been reported to cause breast infections (Mandell, Douglas, and Bennett's principles and practice of infectious diseases (9th edn);2019, Am J Respir Crit Care Med. 2007;175:367).

Horseshoe adrenal gland associated with spinal and vascular anomalies.

Horseshoe (or butterfly) adrenal gland (HAG) is an exceedingly rare congenital abnormality compared to horseshoe kidney. Here we present computed tomography findings of HAG in a 70-year-old man, associated with some spinal and vascular abnormalities; in addition, a brief review of HAG in adult people is presented. In our case, spinal anomalies included a severe scoliosis, a "butterfly" deformation of Th9 vertebra and the presence of a "split lumbosacral thecal sac" at L5 level.
