Article Synopsis
- Soft tissue tumors can grow or stay the same size, but rarely shrink on their own; exceptions include conditions like inflammation and certain benign tumors.
- Intramuscular myxomas are benign tumors that usually appear as slow-growing, painless masses and are typically removed with surgery, which has low recurrence rates.
- This text discusses three unusual cases where intramuscular myxomas in different body areas shrank spontaneously, challenging the usual treatment approaches for these lesions.
Article Synopsis
- MRI is effective at identifying bone marrow involvement in multiple myeloma but struggles with detecting bone lesions, prompting a study to test new MRI techniques (ZTE and BB) against whole-body CT as a reference.
- The study included 47 patients diagnosed with multiple myeloma or at high risk, assessing the performance of ZTE and BB MRI sequences alongside PET/CT scans for detecting osteolytic lesions.
- Results showed that experienced radiologists achieved high accuracy (98%) with both MRI techniques, but there were noticeable discrepancies in detection rates across different regions, particularly with an increased false-negative rate in the spine when using ZTE.
Hourglass-like constrictive neuropathy should be considered in patients with unexplained peripheral neuropathy symptoms, as imaging may show nerve constriction without evidence of intrinsic or extrinsic compression.
View Article and Find Full Text PDFImmune-mediated necrotizing myopathy (IMNM) is a rare type of auto-immune myositis, characterized by symmetric muscle pain, proximal weakness, elevated serum CK levels and pathologic findings of necrotized muscle fibers. IMNM may be seronegative, associated with anti-signal recognition particle (SRP) antibodies or anti-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) antibodies, the last widely related with statin use. This last entity affects only 2 to 3 of 100,000 patients under statins.

- - Certain genetic syndromes can be identified through unique traits visible in medical imaging.
- - Radiological findings can provide critical clues that help in diagnosing these syndromes.
- - This means that doctors can sometimes diagnose genetic disorders by looking at X-rays or other imaging techniques rather than just relying on physical exams.
Metastatic disease and myeloma present unique diagnostic challenges due to their multifocal nature. Accurate detection and staging are critical for determining appropriate treatment. Bone scintigraphy, skeletal radiographs and CT have long been the mainstay for the assessment of these diseases, but have limitations, including reduced sensitivity and radiation exposure.

- Anti-PD-(L)1 immunotherapies show promise in improving survival rates for various cancers, but they don't work for everyone, leading researchers to use machine learning to analyze patient data for better predictions of survival outcomes.
- The study examined 33 baseline medical variables from 695 advanced cancer patients, creating a random forest model to identify factors that significantly affect overall survival when treated with anti-PD-(L)1 therapies versus other treatments.
- Key findings revealed that high levels of serum lactate dehydrogenase (LDH) and liver metastases predicted poor survival rates; patients with these traits experienced significantly shorter overall survival times, indicating the need for better patient stratification in clinical trials.
Objectives: To assess the distribution of bone erosions and two erosion scores in the feet of patients with gout and analyze the association between erosion scores and monosodium urate (MSU) crystal deposition using dual-energy computed tomography (DECT).
Materials And Methods: We included all patients who underwent DECT of both feet between 2016 and 2019 in our radiology department, with positive detection of MSU deposits. Data on sex, age, treatment, serum urate, and DECT urate volumes were obtained.
Intragastric balloon (IGB) placement for the treatment of obesity is presented as a non-invasive and safe technique leading to significant weight loss. We report a case of an IGB migration that led to small bowel occlusion. Radiological analysis confirmed impaction at 250cm from the angle of Treitz.

However, although rare, some hemangiomas with atypical imaging features (aggressive hemangiomas) can pose a diagnostic challenge.
View Article and Find Full Text PDFAdvances in cancer treatments have lengthened the survival of patients with bone metastases. Optimal control of the symptoms and prevention of the complications associated with bone metastases improve quality of life. Achieving these goals increasingly involves interventional radiology procedures.
View Article and Find Full Text PDFBackground: Drugs targeting programmed death receptor-1 (PD-1) and its ligand PD-L1 have shown activity in multiple malignancies. Considering their novel mechanism of action, whether traditional prognostic scores also apply to patients treated with these drugs is unknown. We investigated whether a baseline 3-point (pt) computed tomography (CT) scan (PS3-CT) score and a 7-pt prognostic (PS7) score allowed identifying long-term survivors on anti-PD-1/-L1 therapy.
