Abstract:
Seventy-year-old man, admitted with ileus, was pointed out RA tumor at routin abdominal ECHO. UCG, CT and MRI revealed RA tumor with a stalk attached to inter atrial septum. We resected the tumor and pathological study showed organized thrombus containing bacteria. We suspected that bacteremia due to the IVH catheter was the cause of the thrombus.
Insights
A right atrial tumor in a 70-year-old man was found to be an organized bacterial thrombus. This cardiac mass was suspected to be caused by bacteremia from an intravenous catheter.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Right atrial masses can present diagnostic challenges.
- Intravenous catheter use is associated with infectious complications.
Observation:
- A 70-year-old male presented with ileus and was incidentally found to have a right atrial (RA) mass on abdominal echocardiography.
- Further imaging (echocardiogram, CT, MRI) confirmed an RA mass attached to the interatrial septum via a stalk.
Findings:
- Surgical resection of the RA mass was performed.
- Pathological examination revealed an organized thrombus containing bacteria.
- The likely source of bacteremia was an indwelling venous (IVH) catheter.
Implications:
- This case highlights a rare cause of cardiac masses secondary to catheter-related bacteremia.
- Prompt diagnosis and management of cardiac masses are crucial.
- Understanding the link between IVH catheters and cardiac thrombus formation is important for patient care.
