An indication for a lymphography is:

Lymphography is a radiologic procedure used to visualize the lymphatic system, particularly helpful in diagnosing conditions related to lymphatic vessels and lymph nodes. Peripheral swelling, which is a common indication for lymphography, can result from various underlying issues affecting the lymphatic system, such as lymphedema or lymphatic obstruction. In such cases, assessing the lymphatic pathways becomes crucial for diagnosing the cause of swelling and planning appropriate interventions.

When peripheral swelling occurs, it can indicate problems like lymphatic blockage or inflammation, making this imaging technique beneficial in determining the extent of involvement and guiding treatment decisions. By visualizing the lymphatic structures, lymphography can help in the identification of tumors, inflammation, or other pathologies that may be contributing to the swelling.

Other conditions mentioned, while potentially leading to swelling, do not specifically pertain to the lymphatic system's evaluation. Thus, focusing on peripheral swelling as an indication highlights the importance of understanding the lymphatic response and assisting definitive diagnosis in cases where lymphatic compromise is suspected.
