Article Synopsis
- The study evaluated imaging tests (ultrasound and CT scans) in patients diagnosed with anisakiasis to identify signs related to the disease based on where it occurred in the gastrointestinal tract.
- Findings showed that in gastric cases, wall stratification and thickening, along with fat stranding and ascitic fluid, were common; while in intestinal cases, wall thickening and fat stranding were predominant.
- The research emphasizes the importance of recognizing these imaging signs for better diagnosis and management of anisakiasis in emergency settings, highlighting higher rates of intestinal and multifocal involvement than previously reported.
According to the main international clinical guidelines, the recommended treatment for locally-advanced rectal cancer is neoadjuvant chemoradiotherapy followed by surgery. However, doubts have been raised about the appropriate definition of clinical complete response (cCR) after neoadjuvant therapy and the role of surgery in patients who achieve a cCR. Surgical resection is associated with significant morbidity and decreased quality of life (QoL), which is especially relevant given the favourable prognosis in this patient subset.

Method: Retrospective study on 100 MRI records (1.5 T, 2011-2016) from patients with rectal cancer (reference standard: histology of surgical specimens).
Objective: To assess the added value of diffusion-weighted imaging (DWI) to high-resolution T2-weighted sequences (HRT2w) in MRI detection of extramural venous infiltration (EMVI), according to the previous experience of radiologists.
Methods: A cross-sectional study of a retrospective database including 1.5 T MRI records from 100 patients with biopsy-proven rectal cancer (2011-2016; 75 male/25 female, average 63 y/o), which included primary staging (54) and post-chemoradiotherapy follow-up MRIs (46).
Purpose: To analyze changes in MRI diagnostic accuracy in main rectal tumor (T) evaluation resulting from the use of diffusion-weighted imaging (DWI), according to the degree of experience of the radiologist.
Methods: This is a cross-sectional study of a database including one hundred 1.5 T MRI records (2011-2016) from patients with biopsy-proven rectal cancer, including primary staging and post-chemoradiotherapy follow-up.
Article Synopsis
- Inflammatory pseudotumors are rare, reactive masses that can occur in various locations, including the lungs, and should be considered when diagnosing lung nodules.
- Despite their low occurrence, they typically show low malignancy and respond well to surgical and pharmacological treatments.
- A review of two cases in a hospital highlighted the effective diagnosis and treatment of pulmonary inflammatory pseudotumors in patients presenting with vague respiratory symptoms and suspicious lung nodules.
