Additional response, thanks! I like this for complex intratendinous ganglion, Phil. To tie h/o past surgery, it could have been background mucoid degeneration with a seroma that grew out of control. I have seen pretty large ganglia, not quite as big as this, within the substance of the PTT and peroneals. My two cents. On […]

Would you help with an opinion on this! F/50yr, Come in to hospital because of left orbital swelling and multiple scalp masses. Am thinking it’s a Meningeal Hemangiopericytoma/fibrous tumor – but due to it being multifocal do you have any opinions ? Thank you in advance. Simon

I think an atypical lipoma with focal areas of fat necrosis should be among the differentials. Any trauma in the history? Deep growing quite large fatty lesion – I think surgical removal of the mass will bring the diagnosis. /Gunnar I was inclined to report this as a parosteal lipoma, but cases I have seen

A doctor sticked a niddle months ago in the joint to deliver some corticosteroids for the pain. I reported severe degeneration secondary to inflammation, effusion, erosions, synovitis.

Hi everyone 50 y.o. male with persistent lateral pain 6 months after trauma. I’m not sure about the distal peronaeus longus tendon: are those intratendinous split lesions or just normal appearance? My "sentiment" is that it’s more or less normal, or age appropiate. I don’t want to overdiagnose this. There’s also a visible sprain of

Anyone with any good insights into the signal changes in the femoral epiphyses of this 14 yo pediatric pt? Sort of serpiginous low t1/t2 signal outline with central fatty marrow and no double line sign. MR was for right hip pain. I was thinking maybe reparative phase of Legg calve perthes? Thanks in advance. -micah

Thanks to the many people who offered differential diagnosis possibilities. I reported that the DDx includes benign and malignant lesions, despite the chronic / indolent history. I reported that the DDX included but was not limited to IPEH, dematofibrosarcoma protruberans, Squamous Cell Ca related to chronic scar and pilomatricoma…. additional suggestions included benign vascular malformation,
