Résumé
Osteomas are the most frequently observed benign bone tumors of paranasal sinuses. These slow-growing, benign tumors are often asymptomatic and typically discovered incidentally on radiological exams conducted for unrelated complaints. However, their potential for significant complications arises when they grow to a size or position that impacts adjacent structures. Large osteomas may obstruct sinus drainage, leading to secondary infections such as chronic sinusitis, or extend into the orbit or intracranial space, causing symptoms like proptosis, diplopia, vision loss, headaches, and even cerebrospinal fluid leaks in cases of dural invasion. Intracranial extension, while rare, can lead to serious complications, including meningitis, brain abscess, and mucocele formation. This article presents a 70-year-old male with recurrent chronic rhinosinusitis and nasal polyps, who had undergone functional endoscopic sinus surgery three years prior. At follow-up, the recurrence of nasal polyps was observed alongside a newly developed ethmoidal osteoma. Cases like this underline the importance of regular postoperative imaging, especially in patients with recurrent sinonasal issues, as osteomas can develop post-surgically. Some studies suggest that local factors such as inflammation or surgical trauma may play a role in the growth or initiation of osteomas, though this remains to be fully understood. This case highlights the clinical value of CT and MRI in the identification, differentiation, and management of paranasal sinus osteomas, as well as the importance of vigilance in long-term follow-up for patients with chronic sinonasal conditions.
