Diagnosis and Treatment of a Symptomatic Posterior Cruciate Ganglion Cyst in a Child with Autism

Figure 1

Preoperative magnetic resonance images of the left knee revealed large round-shaped cystic mass encasing the PCL with homogeneous low-signal intensity on sagittal proton density-weighted image (PDWI) (a) and on turbo spin echo (TSE) imaging (b). The lesion appears highly hyperintense on sagittal and coronal turbo inversion recovery magnitude (TIRM) images (c, d).
