Osteoid osteoma and osteoblastoma of the cervical spine in the pediatric population: analysis of the literature and experience with four operated cases.
Childs Nerv Syst
December 2024
Departement of Pediatric Neurosurgery, Hôpital Femme Mère Enfant, Lyon, France.
Background And Aim: Osteoid osteoma (Oo) and osteoblastoma (Ob) are rare primary bone tumors with a higher prevalence in the second decade of life. Treatment can be conservative, but in cases of spinal location, resective surgery is of great importance but may be challenging.
Material And Methods: We report four pediatric cases of Oo and Ob managed in our unit, with different locations at the level of the cervical spine.

Cementoblastoma is a benign odontogenic mesenchymal tumor characterized by cementum production. Cementoblastoma is considered a relatively rare neoplasm with a predilection to the posterior region of the mandible. The main clinical differential diagnoses include hypercementosis, cemento-osseous dysplasia, condensing osteitis, idiopathic osteosclerosis, osteoblastoma, odontoma, and osteosarcoma.

Conventional high-grade osteosarcomas are characterized by aggressive radiologic features, cytologic pleomorphism, and complex genomics. However, rare examples of osteosarcomas remain challenging due to unusual histology, such as sclerosing or osteoblastoma-like features, which may require molecular confirmation of their complex genetic alterations. We have encountered such a case in a 17-year-old man, who presented with a third metatarsal sclerotic bone lesion, found incidentally in the work-up of a foot trauma.

Background: Aneurysmal bone cysts (ABCs) are rare, benign, yet locally aggressive lesions that contain blood-filled channels that rarely occur in the thoracic spine of adults. The literature on the treatment of spinal ABCs is sparse, but the consensus is to achieve gross-total resection (GTR) due to these lesions being locally aggressive and to prevent recurrence.
Observations: This report describes a 35-year-old female admitted with back pain and right T5 dermatome radiculopathy without any inciting events.
