Computed Tomographic Assessment of Brain and Limited Paranasal Sinuses Study in Subjects with Headache at Bhuj, Kutch
Computed Tomographic Assessment of Brain and Limited Paranasal Sinuses
Background: Recent advances in Commuted Tomography (CT) and magnetic resonance imaging (MRI) methods have increased the importance of imaging examinations in the assessment of abnormalities affecting the head and neck. Present study was done with an aim to assess the utility of CT of the brain in the identification of causative factors for headache. To determine the additional value of acquiring limited paranasal sinus images after evaluation of the brain in patients with headache. Subjects and Methods: This is a prospective study done in 150 cases with a primary complaint as headache undergoing Computed Tomography of the brain and limited paranasal sinus CT scan in Department of Radiodiagnosis at Gujarat Adani Institute of Medical Science, Bhuj, Kutch, Gujarat during the period from July 2020 to December 2020. Results: Of the 150 patients studied, 71 patients were males and 79 patients were females. Among the 71 male patients studied significant abnormality was detected on imaging in 9 male patients. Imaging findings were normal in 132 cases of the study population and significant abnormality was detected in 18 cases. Among the 18 patients with abnormality on imaging, 10 had intracranial abnormality as the cause for headache and 8 patients had sinusitis as the cause for headache. Among the 8 patients with sinusitis, 4 patients had acute onset of headache following runny nose and fever. Conclusion: Screening in headache with CT not only helps in identifying an abnormality but also helps to rule out structural causes for headache thereby reducing patient apprehension. Additional acquisition of limited PNS sections increases the yield from imaging, reduces the cost from dedicated PNS imaging, and helps to differentiate paranasal sinus cause of headache from the intracranial cause. CT is very accurate and sensitive in diagnosis and characterization of various abnormalities affecting the nasal cavity and PNS.
