case_images: No obvious nidus was identifiable [Figure 1].
case_images: CT of the thigh outlines sclerosis, but not the nidus

case_images: The CT scan of the right lower limb with a bone window could only outline the sclerosis, but not the nidus [Figure 2].
case_images: Bone SPECT showing focal uptake of the nidus

case_images: SPECT acquisition revealed a focal avid uptake in the lower shaft of the right femur [Figure 3].
case_images: X-Ray of the right leg showing sclerosis on the medial aspect of the right tibia

case_images: SPECT acquisition revealed the focal avid uptake of the nidus localized to be anterior in the three-dimensional reconstructions of the coronal, sagittal, and axial planes [Figure 4]. Surgical excision was done by an anteriomedial approach and the entire lesion was resected.

case_images: CT of both legs identified sclerosis, but nidus is indefinable

case_images: A plain radiograph of the right leg showed a large, diffuse and intense sclerosis on the medial aspect of the right tibia with no periostial reaction [Figure 5].
case_images: SPECT showing central active nidus with decremental activity toward the periphery, typical of an osteoid osteoma

case_images: A CT scan of both legs in the bone window also identified the sclerosis with nidus as being indefinable [Figure 6].
