Ganglion cysts usually arise from the tissues around the facet joints. It is usually associated with degenerative cahanges in facet joints. Bilateral thoracic ganglion cysts are very rare and there is no previous case that located in bilateral intervertebral foramen compressing the L1 nerve root associated with severe radiculopathy. We report a 53 years old woman who presented with bilateral gr...

A ganglion is a cystic mass with myxoid matrix that occasionally occurs within muscles, tendons, and menisci. A ganglion cyst within the knee is very rare, with few reports to be found. We are reporting eight cases of a ganglion within the knee joint. Our cases include two ganglia in the infrapatellar fat pad which have not been previously reported. Ganglion cysts do not have specific symptoms....

BACKGROUND Intra-articular ganglion cysts of the knee are rare. Here we report a case of an arthroscopically confirmed ganglion cyst arising from the posterior cruciate ligament (PCL) along with preoperative magnetic resonance imaging (MRI) findings. CASE PRESENTATION A 39-year-old female admitted a hospital with left knee pain with flexion and extension. MRI revealed a cystic lesion along th...

The pathogenesis of juxtafacet cysts is closely related to degenerative instability of the lumbar spine and degenerative changes in the ligamentum flavum and the facet joint. A 56-year-old man presented with severe right thigh pain and numbness for 1 month after a laminar fracture of the L4 spine. Magnetic resonance imaging revealed a heterogenous cystic mass surrounding the facet joint between...

We present the case of a 55-year-old woman with a presumed ganglion cyst associated with the anterior cruciate ligament (ACL), demonstrated by MRI. The ACL is an uncommon location for ganglion cysts to occur.

BACKGROUND Tunnel enlargement is frequently seen in short-term follow-up after anterior cruciate ligament reconstruction (ACLR). According to new evidence, tunnel enlargement may be followed by tunnel narrowing, but the long-term evolution of the tunnels is currently unknown. HYPOTHESIS/PURPOSE The hypothesis was that tunnel enlargement is followed by tunnel narrowing caused by ossification a...

Although juxtafacet cysts of the lumbar spine are being reported with increasing frequency, hemorrhage from a ganglion cyst is rare, and the pathophysiologic mechanism of the hemorrhage from the cyst is still unclear. A 75-year-old male presented with sudden radicular leg pain caused by hemorrhage from the ganglion cyst. Computed tomography revealed bony erosion of vertebral body and multiple p...
