case_images: 17-year-old female with pain in the left heel diagnosed as due to an aneurysmal bone cyst. Lateral X-ray of the left foot shows radiolucent lesion (arrow) leading to expansion on the postero-lateral part of the calcaneus.

case_images: On the lateral foot X-ray, there was an expanding radiolucent mass on the postero-lateral part of the calcaneus [Figure 1].
case_images: 17-year-old female with pain in the left heel diagnosed as due to an aneurysmal bone cyst. CT scans of the left foot a) sagittal and b) coronal views show lytic mass lesion (arrow), 35 x 25 mm in dimension, localized postero-laterally, leading to cortical bone erosion, expansion, and destruction.

case_images: CT scan showed a lytic lesion with soft tissue density leading to erosion and expansion of the bone cortex, located on the postero-lateral part of the calcaneus [Figure 2].
case_images: 17-year-old female with pain in the left heel diagnosed due an aneurysmal bone cyst. MRI on the postero-lateral part of the calcaneus shows a cystic mass lesion in the medullary cavity. a) T1W and b) T2W sequences show heterogeneous hyperintense sclerotic rim (red arrow) surrounding the medullar component and central heterogeneous hyperintense septae formations (green arrow). T2W sequence shows blood level components (blue arrow). c) Image following intravenous contrast media administration shows contrast enhancement surrounding the lesion (red arrow) and in the septae formations (blue arrow).

case_images: The T1-weighted (T1W) sequence showed heterogeneous hyperintense septae formations. T2W MRI also revealed heterogeneous hyperintense septae formations, blood level components, with contrast enhancement on the surrounding tissue and septae [Figure 3].
