MRI
characteristics of cysts and “cyst-like” lesions in and around the knee: what the radiologist needs to know. Intraosseous ganglion cyst. The axial (a) and coronal (b) fat saturated proton density weighted images demonstrate a solitary, unilocular cystic lesion (arrows). Note the sclerotic rim (arrowheads) and mild reactive bone oedema (asterisk)

Spectrum of
MRI features of ganglion and synovial cysts. Intraosseous ganglion cyst of the tibia incidentally depicted in a 40-year-old man who underwent an MRI scan due to intermittent, subacute non-specific knee pain. Sagittal FS PD-WI shows a metaepiphyseal, large, multiloculated cystic lesion of the tibia, which communicates with the articular surface through a thin stalk (arrow) extending into the interspinous region, close to the anterior cruciate ligament tibial insertion. Tb, tibia; ACL, anterior cruciate ligament
An intraosseous ganglion (plural: ganglia) is a benign subchondral radiolucent lesion without degenerative arthritis.
Epidemiology
Tends to occur in middle age.
Clinical presentation
Patients may have mild localized pain.
Pathology
They are uni-/multilocular cysts surrounded by a fibrous lining, containing gelatinous material.
Origin
Location
Common locations are:
- epiphyses of long bones (medial malleolus, femoral head, proximal tibia, carpal bones)
- subarticular flat bone (acetabulum)
Radiographic features
Plain radiograph
Typically well-demarcated solitary lytic lesion, with a sclerotic margin. No communication with joint can be demonstrated.
MRI
- solitary, unilocular or multilocular
- usually sclerotic rim is present
Bone scan
Bone scans demonstrate increased radiotracer uptake (in 10%).
Differential diagnosis
- post-traumatic/degenerative cyst
