Patient Presentation:
A 40-year-old male presented with one month of intermittent right knee pain gradually worsening and aggravated by bending and walking.

History:
He was hit on the lateral side of the right knee by a rock that fell at work two years prior to his presentation. After this injury, a protrusion behind his right knee appeared and gradually increased in size. He reported associated chest pain and joint swelling and denied arthralgia, fever, headache, nausea, rash, or vomiting. He was initially referred to Orthopedics/Sports Medicine with a chief complaint of popliteal cyst

Physical Exam:
A fixed 5 cm mass Case Photo #1 in the posterior knee. This had mild warmth, no significant erythema or fluctuance which caused a limited range of motion.
