We report a 17-year-old female who presented complaining of back pain. A mass, the size of 5cm×6cm was seen on the right laminae of Th5. The tumor had a radio-lucent area on X-P and a cystic lesion was seen on CT scanning. T1-weighted images showed high intensity and T2-weighted images were of high intensity in a low intensity area on MRI. On angiography, the mass was shown to be hypervascular. A pathological diagnosis of ‘Benign osteoblastoma’ was made.
