Mediastinal tumors develop in one of three areas of the mediastinum: the anterior (front), the middle, or the posterior (back). The previously seen left paraspinal cystic mass at the approximate T9 level is again noted. Because cystic thymic (and other mediastinal) lesions are not always of water density on unenhanced or contrast-enhanced CT, relatively hyperdense cystic lesions on CT are often misinterpreted as solid, leading to misguided differential diagnoses and unnecessarily.

However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy. (C) Coronal view in MRI showing a left dumbbell-shaped paraspinal tumor. Although clinical history and examination may suggest the diagnosis, imaging is required to confirm the clinical diagnosis and assess the anatomical extent of the lesion before treatment. Postoperative paraspinal fluid collections can present a management dilemma to both radiologists and surgeons. The cyst is also known as mesothelial inclusion cyst, benign cystic mesothelioma, or coelomic cyst (2, 5). Soft tissue calcifications pop up all of the time, and it behooves the radiologist to say something intelligent about them. They can cause pain from the pressure on the spine. Mediastinal cystic masses are well-marginated, round, epithelium-lined lesions that contain fluid. The DSA image (bottom Left) after selective catheterization of the left vertebral artery demonstrates pooling of the contrast in the cystic mass (red arrow). The diagnosis of incidental adrenal masses has. Mediastinum-RADIOLOGY. Fluid density within the cyst is the general rule, but can contain soft tissue density making it indistinguishable from other mediastinal masses radiographically.
