Cleo’s diagnostic plan would include which combination of tests?

• A. CT, rhinoscopy, biopsy, histopath
• B. CT, rhinoscopy, cytology, histopath
• C. MRI, endoscopy, biopsy, histopath
• D. X-ray, rhinoscopy, biopsy, cytology

Answer: (A)

Evaluating nasal or sinonasal disease requires three things: a clear picture of the anatomy and extent of disease, direct visualization to identify suspicious areas, and a definitive tissue diagnosis. CT excels at showing bone detail and the full extent of involvement in the nasal passages and sinuses, plus it’s quick and accessible for planning procedures. Rhinoscopy provides a direct view inside the nasal cavities, allowing you to see mucosal changes, masses, or obstructions and to guide targeted biopsy to representative areas. A biopsy with histopathology is the gold standard for diagnosis because it preserves tissue architecture, letting a pathologist distinguish between inflammatory, infectious, and neoplastic processes and identify the exact tumor type and grade. Cytology, while useful as a quick, less invasive screening tool, often cannot distinguish certain lesions or reveal architectural patterns as histopathology can, so it cannot replace biopsy in this context. X-ray offers limited soft-tissue detail and is not as informative for planning or definitive diagnosis, and MRI, though excellent for soft tissue, is less practical as a first-line imaging modality for nasal disease when CT provides the necessary detail more efficiently.
