Osteoid osteomas are one of the most common benign bone tumors found. They have a characteristic presentation of nocturnal pain relieved with NSAIDs. Diagnosis can sometimes be difficult due to their location or small size on radiographs. In the future, treatment options will continue to shift towards minimally invasive options, such as arthroscopic excision.
