Q- A 40-year-old woman presents to her regular physician for evaluation of a left adrenal mass. This mass was seen by accident last week on a CT scan during a visit to the emergency room for abdominal pain. Her vital signs, physical examination and review of systems are all normal. Her past history and family history are unremarkable.

What is the first step in management for this patient?

A- Assure the patient and schedule another CT scan after 6 months

B- Order hormonal assay to evaluate if the mass is functional or not

C- Order MRI of the mass

D- Perform a needle biopsy

E- Refer to surgery for removal of the adrenal mass

B- Order hormonal assay to evaluate if the mass is functional or not- This is a case of incidentaloma, as its name implies, a tumor that is discovered incidentally. The first crucial step is to find out if it is functional or not. Hormonal assay is the most appropriate method to figure that out.

  1. Uptodate says CD8 T-lymphocytes for drug eruption?

  2. A good question! This infarction affects the Left anterior descending artery. It supplies blood to the front (anterior wall) and part of the side (anterolateral wall) of the left ventricle, to the top of the left ventricle, and to most of the wall between the ventricles (interventricular septum). Thank you

  3. Why RAD in anterolateral MI ?
