We present a case of hereditary exostoses with a large pedunculated osteochondroma within the left pulmonary fissure mimicking a pulmonary nodule. In the setting of apparent pulmonary nodules and known HME, identifying a bony stalk extending from the "pulmonary nodule" to an adjacent bone may obviate the need for further assessment with chest CT.
