Patient Data
Age: 30
Gender: Male
From the case:
Intra-thoracic kidney
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/90034/annotated_viewer_json?iframe=true\u0026lang=us"}
X-ray shows a large homogeneous, well defined mass projected over the cardiac silhouette. There is no distortion of the cardiac contour or loss of the heart borders. Appearances likely reflect a large posterior mediastinal mass but there is no rib splaying or vertebral abnormality.
From the case:
Intra-thoracic kidney
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/90036/annotated_viewer_json?iframe=true\u0026lang=us"}
Subsequent CT shows that the mass is in fact an intra-thoracic kidney with the vascular pedicle extending from the abdomen.
Case Discussion
This case highlights one of the more unusual differentials for a posterior mediastinal mass.
