Consider the Probe 3: So I've found the effusion, now what?

A 74 y/o F with pmhx of metastatic breast cancer, IDDM, HTN presents after a syncopal episode.  The patient notes that for the past 2-3 days she has been experiencing some lightheadedness and shortness of breath with exertion.  She is presently undergoing chemotherapy (I'd throw in some random chemo drus here, but lets face it, we wouldn't know them anyways...) and radiation.  She notes that she hasn't been eating/drinking very well.  She denies fever, cough, hemoptysis, leg pain/swelling.  She has mild nausea but no abdominal pain.

 Consider the Probe: US Findings of CRAO (CREDIT DR. THAKKAR) While most of us have grown (somewhat) comfortable utilizing POCUS to delineate Retinal Detachments from Vitreous Pathology (detachment vs hemorrhage), who knew that our favorite bedside tool could help point us in the direction of another "can't miss" diagnosis.  Dr. Thakkar explains the POCUS findings seen with Central Retinal Arterial Occlusions.  Enjoy and remember the next time you are on shift to CONSIDER THE PROBE... Special thanks to Dr. Pankthi Thakkar.
