ABSTRACT: Haller cells are infraorbital ethmoidal air cells that may narrow the osteomeatal complex and contribute to sinonasal pathology when large or extensively pneumatized. We present a rare case of a giant right-sided Haller cell measuring 21 × 17 × 16 mm (volume ≈ 5.7 cm3), associated with chronic maxillary sinusitis. Recognition of such variations on imaging is crucial for accurate diagnosis and surgical planning.
