Visualization of Intrapulmonary Lymphadenopathy on Vessel-Suppressed Computed Tomography in a Patient With...

We report a case of a 55-year-old woman diagnosed with sarcoidosis involving multiple intrapulmonary lymph nodes that were clearly visualized on vessel-suppressed CT imaging. Intrapulmonary lymph node involvement in patients with sarcoidosis has been reported less frequently and has not been well discussed. This may be attributed to the fact that intrapulmonary lymph nodes present as small nodular lesions located along pulmonary vessels, making them difficult to detect on conventional imaging. Vessel-suppressed CT enhances visualization of pulmonary lesions by selectively suppressing vascular structures. This case highlights the clinical utility of vessel-suppressed CT for improved detection of intrapulmonary lymph node lesions in the diagnosis of sarcoidosis.
