Spontaneous osteochondroma resolution in a young female: imaging and histopathological findings

To report the first operated and histopathologically studied case of spontaneously resolving solitary osteochondroma. An 18-year-old girl presented with leg pain of 2 months' duration. She had been diagnosed to have a proximal tibial osteochondroma since the age of 9 years. Excision biopsy of the tumor remnant and its surrounding tissue was done after CT and MRI imaging.
