a–d MRI images and e a high-resolution ultrasound image for Hoffa’s pad fat ganglion cyst. a Axial T2WI, b sagittal T2WI, c sagittal T1WI, and d sagittal PD fat suppression demonstrated a large well-defined lobulated intra-articular cystic lesion within the infrapatellar fat pad. It elicited a low signal on T1WI and a bright signal on T2WI and PD fat suppression (red open arrows). e B-mode image demonstrated anechoic lobulated and septated Hoffa’s pad fat cyst concordant with the MRI findings
