- Thymic cyst | Radiology Reference Article - Radiopaedia. org
Thymic cysts typically manifest as unilocular or multilocular cystic masses with well-defined walls Lesions can be lobulated and may have soft-tissue attenuation components Some thymic cysts may have increased CT attenuation if hemorrhage or infection occurs as a complication
- The Radiology Assistant : Thymic masses and mimics
Although most thymic masses are found incidentally on chest CT, MRI is the best imaging tool to further differentiate a possible mass T2W-images help to detect cystic components T1W-images in- and out-of-phase help to detect intracellular fat and to distinguish a normal thymus and thymic hyperplasia from thymic neoplasms and lymphoma
- Pitfalls in the Imaging and Interpretation of Benign Thymic . . . - AJR
Observation of homogeneous attenuation and a round, oval, or saccular smoothly marginated lesion in the thymic bed on CT should raise the diagnostic possibility of a thymic cyst, even if there is hyperattenuation, and further evaluation by MRI should be recommended, to distinguish a simple cyst from a complex cyst or solid lesion
- Longitudinal CT and MRI Characteristics of Unilocular Thymic Cysts
Most thymic cysts changed in volume (31 of 34 cysts [91%]), CT attenuation (15 of 35 cysts [43%]), and T1-weighted MRI signal (12 of 18 cysts [67%]) over time None developed mural irregularity, nodularity, or septations
- Pathology Outlines - Thymic cyst
Have thin wall with a few layers of bland squamoid cells and thymic tissue in wall, no inflammation, no cholesterol granulomas, no hemorrhage Multilocular cysts: May have more layers of squamoid, cuboidal, columnar, micropapillary or mixed glandular epithelium
- The thymus: what’s normal and what’s not . . . - Clinical Radiology
Follow-up MRI is pending for 34% (19 55) patients with either suspected thymic hyperplasia, thymic cysts, or a foregut duplication cyst Surgical opinions are awaited for two indeterminate lesions: one cystic and one solid
- Special Computed Tomography Imaging Features of Thymic Cyst
To explore the features and diagnostic value of computed tomography (CT) imaging in cases of thymic cysts A total of 24 cases of the thymic cysts (confirmed by postoperative pathology) were retrospectively analyzed
- Thymic cyst | Radiology Case - Radiopaedia. org
The thymic cyst is usually a well-circumscribed homogeneous lesion, located near the thymic bed It has round, oval or saccular morphology, and is frequently purely cystic, with no soft tissue components or internal septa
