Pediatric chiasmatic cavernoma hemorrhage: a case report and review of the literature

BACKGROUND: Cavernomas arising in the region of the optic pathway are extremely rare, and data on their clinical characteristics are very limited. CASE PRESENTATION: We report the case of a 16-year-old healthy boy who presented with headache and sudden visual field loss. Imaging examination revealed a suprasellar lesion with hemorrhage. A rare case of cavernoma of the optic chiasm region was confirmed via craniotomy and postoperative pathological examination. Close follow-up revealed significant improvement in visual field defects. The case report data on chiasmatic cavernomas from recent years have also been comprehensively reviewed. CONCLUSION: This study emphasizes the importance of prompt diagnosis of and the effectiveness of timely surgical treatment for a chiasmatic cavernoma causing hemorrhage and vision loss.
