mediastinal lymph node TB

Its very easy at times and at times too difficult to logically outline a probable lymph node shadow on a X ray chest.

In the image on right, you can see a bean shaped right mediastinal lymph node.

The presence of these shadows is always required to be confirmed by a lateral Xray chest and / or a chest Ct scan.

Presence of these solitary or multiple nodes usually suggests tuberculosis, but can be an early sign of lymphoma or other chronic granulomatous diseases and HIV.

Lymph node TB is a commonest form of TB in school age children. the diagnosis however may be supported by a Matoux test and TB contact and / or other clinical features.
