Applications of new radiological scores: the Node-rads in colon cancer staging.

PURPOSE: The study focuses on the evaluation of the new Node Reporting and Data System 1.0 (Node-rads) scoring accuracy in the assessment of metastatic lymph nodes (LN) in patients with colon carcinoma. MATERIAL AND METHODS: From April 2021 to May 2022, retrospective chart reviews were performed on 67 preoperative CT (Computed Tomography) of patients undergoing excisional surgery for colon cancer at the Polyclinic of Bari, Italy. Primary endpoints were to assess lymph node size and configuration to express the likelihood of a metastatic site adopting the Node-rads score system, whose categories of risk are defined from 1 (very low) to 5 (very high). The nodal postsurgical histological evaluation was the gold standard. The relationship between Node-rads score, LN size, configuration criteria (texture, border and shape) and the presence of histological metastases was statistically evaluated. RESULTS: All surgical specimens examined had correlation with Node-rads score. They were significantly more likely to present nodes micrometastasis those patients with (a) spherical LN shape (82.8%), (b) with lymph node necrosis (100%), (c) irregular borders (87%) and (d) the LN short axis more than 10 mm (61.9%). CONCLUSIONS: Our experience highlights how the Node-rads system proposes an intuitive and effective definition of criteria to standardize the lymph node radiological reports in colon cancer disease. Further studies are needed to streamline the classification of the nodal and peripheral LN in all the oncological imaging.

Diagnostic difficulties of antero-superior mediastinal masses with cardiac infiltration. Endovascular bioptic alternative approach.

The diagnosis of mediastinal masses is challenging due to the variety of possiblepathologies , and its definitive diagnosis is mainly confirmed by histological evaluation. Sometimes some lesions may have a greater intravascular rather than mediastinal development and the collection of a biopsy sample becomes even more complex. In these cases endovascular catheter biopsy is helpful in the collection of the necessary biological material, having to adapt to the type of surface and consistency of the mass to be analyzed. Endovascular catheter biopsy was performed with a biliary forceps to sample a mediastinal mass with greater endovascular and cardiac development, with a hard and difficult to sample surface. The histological result was diagnosed with non-hodgkins lymphoma.

"TransIent perivascular inflammation of the carotid artery (TIPIC) syndrome" as a rare case of laterocervical pain: Multimodal diagnosis.

''TransIent Perivascular Inflammation of the Carotid artery (TIPIC) syndrome" is an unusual cause of unilateral neck pain, due to a nonspecific inflammation of the carotid artery. This entity has been for long known as "carotidynia" and described as a syndrome rather than a distinct pathologic entity. Recently, the presence of structural abnormalities of the carotid artery wall has been demonstrated, leading to the introduction of radiological criteria which, in the appropriate clinical context, allow to diagnose TIPIC syndrome. TIPIC syndrome is a rather rare disease and, since its first description by Fay in 1927, only a small series of patients have been published. The interest of our case lies in the fact that diagnosis and follow-up were assessed on ultrasound and magnetic resonance imaging, demonstrating that a correlation between clinical evolution and radiological findings does exist. In addition, DWI sequence was performed at the time of diagnosis and at resolution. To our knowledge, such an assessment has never been reported in the previous literature.
