Advance of CT Scan as an Important Imaging Tool in Evaluation of Nasal Polypoidal Masses

Dr. Sufiyan H Mirza, Dr. Priti Kapoor

Abstract :

Introduction: Nasal polyposis is a relatively common condition found in the general population and in high percentage among some selected group of patients. The polyps are found in patients with aspirin intolerance, asthma,cystic fiosis and chronic rhinosinusitis. The characteristic radiological changes of nasal polyposis are familiar to ENT surgeons and radiologists and are well demonstrated and characterized on CT.

Objectives: To study the CT scan imaging profile of nasal polypoidal lesions and characteristic imaging features of different nasal polypoidal lesions. To study the comparison between CT Scan Imaging diagnostic consistency in Non–neoplastic and neoplastic polypoidal lesions.

Methods: Study of 50 patients of all ages and of either sex presenting with nasal polypoidal lesions in the Department of ENT, MGM Medical College and Hospital, Kamothe, Navi Mumbai for a period of 1 year. Plain and contrast enhanced CT sequences of nose, paranasal sinuses, orbit and ain with 3–5mm thin slices of axial and coronal views were obtained on soft tissue and bone window settings

Results: Unilateral involvement of sinuses was found in (60%) and bilateral involvement of sinuses was found in (38%) patients. Widening, ballooning or destruction of the osteomeatal complex was revealed in 100% of our patients while evidence of fungal disease with double density sign was present in (10%) patients. Intraorbital extension with destruction of lamina papyracea was found in (6%) and destruction of sinus wall with expansion or thinning was noted in (20%). Extension to the anterior cranial fossa via the criiform plate and middle cranial fossa via the sphenoid sinus was found in (6%) cases each. Pressure erosion on the septum (4%) cases each.
