Learning objectives To review the radiological anatomy of the prevascular mediastinum To characterize the typical and atypical imaging features associated with various tumors To recognize the common diagnostic pitfalls and improve accuracy in interpretation
Read more Background Introduction          Despite its reduced diversity of structures, the prevascular space represents the site of more than 50% of the tumors that can occur in the mediastinum. Moreover, several tumors from adjacent structures can extend into this compartment, increasing the difficulty of diagnosis. [1] Anatomy            According to the ITMIG (The International Thymic Malignancy Interest Group) classification, the space of the mediastinum bounded anteriorly by the sternum and posteriorly by the pericardium along with the great...
Read more Findings and procedure details          Tumors found in the prevascular mediastinum are either primaries of local structures i.e. thymic tumors, germ cell tumors, lymphomas, mesenchymal tumors, ectopic thyroid and parathyroid tumors, or secondary tumors by direct or metastatic spread, more commonly from lung, breast or thyroid tumors. [fig 1]         While CXR usually raises the question of mediastinal mass and MRI solves tissue-specific problems, CT plays a key part in characterizing and differentiating the source of a lesion due to...
Read more Conclusion             CT evaluation and characterization of prevascular mediastinal tumors plays a pivotal role in diagnosis and also in guiding the treatment. Diagnostic pitfalls and atypical presentations can complicate this process, leading to potential misinterpretations. To avoid errors and ensure accurate diagnosis is important to recognize the diverse imaging features, understand tumor behavior, and correlate findings with clinical data. Understanding the roles and limitations of various imaging modalities is helpful in the evaluation of mediastinal masses. ...
