35 yo male with vague knee pain since 2 weeks. There is a suprapatellar lesion. Do you have an idea what could it be? Fluid with septa and thickened synovium? Hematoma? PDfs, T1W and T2W images are obtained. Additionally partially torn ACL was depicted.

57 yo female with knee pain. Baker cyst was suspected by referring physician. I can see small amount of fluid in SB and partial cartilage loss on MFC. On the lateral side of femoral bone I suspect thrombosis of varicose vein. Can you agree or do you have another suggestions?

There is a case of 45 yo female. The examination was done due to injury in 15th of March. I have a question about bone marrow reconvertion. I can see T1 low signal involved partially subchondral layers of tibial and femoral condyles. Any suggestions about pathologic process?

There is a focal area of high signal in PD FS, slightly decreased in T1, T2 and T2 GRE. It is localized in posterior part of distal femur and has not distinct borders, no changes in cortical part of bone. Would you include it in you report and recommend further investinagion in x-ray and MR with contrast? Patient is a 44 yo female with unspecific symptoms. Photos: PD FS, T2, T2 GRE, T1, T2 GRE

There is a lesion in proxial tibia in 35yo male. It has homogenous T1 and T2 high signal and PD fs low signal. Do you think it may be an intraosseus lipoma? Photos: T2, PD fs, T1.
