ABSTRACT

Diagnosis: Synovial Cyst

History: 6 months of continuous, worsening back pain Radiates to Right KNEE and down to Right MEDIAL ANKLE “Knee and ankle feel funny sometimes when I walk” Pain is not affected by time of day or activity Denies Hx of Trauma Pain is minimally improved by stretching and OTC pain meds

Findings: Low T1 signal round lesion adjacent to the postero-lateral aspect of the thecal sac. Rim is iso-signal on T1 and low signal on T2. Bright on T2-weighted images. Communication with the facet joint. Heterogeneity of cyst likely due to proteinaceous fluid or hemorrhage within the cyst.

Ddx: extruded disk fragments ganglion cysts nerve sheath tumors septic facet arthritis asymmetric ligamentum flavum hypertrophy synovial cyst

Dxhow: MRI and surgical excision.

Exam: VSS, afebrile. Minimal tenderness to palpation in back and leg. Right Patellar Reflex diminished relative to Left side. All other reflexes equal bilaterally. No decreased ROM. Weakness on inversion of R foot. CBC, CMP, ESR, CRP all normal.

No MeSH data available.


Rim is low signal on T2. Bright on T2-weighted images with communication with the facet joint. Heterogeneity likely due to proteinaceous fluid or hemorrhage within the cyst.
