RESUMEN
BACKGROUND: Osteoid osteoma is a benign bone neoplasm which is seen in the long bones of appendicular skeleton. It is rarely seen in the cranium. Skull base osteoid osteoma is extremely rare and has been anecdotally reported. CASE PRESENTATION: The authors report a case of a large osteoid osteoma of the ethmoid with intraorbital and intracranial extension in a 33 year old male patient. He presented with loss of vision in the left eye. The intra-cranial extension was excised through a single burr-hole fronto-orbitotomy. The ethmoid and orbital portions were approached and excised through a Weber-Ferguson incision and inferior orbitotomy. Radical excision of the tumor could thus be achieved through a craniofacial approach. CONCLUSION: Although benign and rare, skull base osteoid osteoma can present with neurological deficit due to its mass effect and involvement of vital structures. A multispeciality team approach is advisable in such cases if radical excision is to be achieved. A craniofacial approach made radical single stage excision of this multicompartmental osteoid osteoma possible with an uneventful postoperative period.
RESUMEN
The increasing frequency of tuberculosis (TB) in both developed and developing countries has continued to make spinal TB an important health problem. The present case report is about a patient who presented to us with progressive back pain and paraspinal mass. We performed endobronchial ultrasound guided needle aspiration from the paraspinal mass. The cytology showed granulomatous inflammation suggestive of TB.
