Sacral osteoid osteoma (OO) is a rare location. The clinical signs are misleading, hence the delay in diagnosis. Through this case, we will put. The aim of this work was to put the light on a clinical sign that may suggest the diagnosis of OO and to report the therapeutic management.
We report the case of an OO located in the left lamina of the first sacral vertebra, revealed by pain in the sacroiliac joint mimicking sacroileitis in a 12-year-old child. Computed tomography and MRI revealed bone lysis in the left lamina of the first sacral vertebra consistent with the diagnosis of OO. Anatomopathological examination of the resection piece confirmed the diagnosis. Surgical removal of the tumor resolved the pain.
The lumbar spine is the most frequently affected area, followed by the cervical, thoracic and sacral regions. Diagnosis of OO is primarily clinical. In typical cases, it is characterized by nocturnal inflammatory pain. It can simulate sciatica or sacroilitis. Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to relieve pain. This is a diagnostic test.
Sacral OO is a rare localization and is often diagnosed late because the symptoms are misleading and polymorphic. For locations in contact with nervous elements, open surgery is the gold standard.
•Vertebral osteoid osteoma is often diagnosed late because of misleading signs.•CT scan is the most effective radiological examination for the diagnosis of osteoid osteoma.•Sacroiliitis is the first differential diagnosis of sacral osteoid osteoma.•Treatment of laminar osteoid osteoma is surgical because radiofrequency can damage spinal nerve cells.
