Résumé

Backgroud: Brain tumors represent a major public health problem, and are generally among the most common brain disorders. Their sequelae are serious. CT can be used to assess intracranial processes.

Objective : Describe the different CT scan presentations of brain tumors in the imaging department of the Ngaoundéré Regional Hospital.

Methodology:  This was a descriptive, cross-sectional study conducted over a period from June 2021 to March 2024, i.e. two years and ten months. We included all patients who presented with a brain tumor on brain CT scans performed during the study period. Variables analyzed included sociodemographic data (age, sex), clinical manifestations and scanographic findings. Statistical analysis was performed using Sphinx v5 and Microsoft Excel.

Results : For our study, we selected 30 patients who had undergone brain scans with brain tumors as findings, 2,64% of all brain scans. The male sex was the most represented at 57%, with a M/F sex ratio of 1.33. Patient age ranged from 1 to 60 years, with an average of 32.29 years. The most common age groups were [0-10y] and [40-50y], with 21.4% each. The most common clinical signs were headache (35%) and motor disorders (32%). In our series, most brain tumor examinations (83.33%) involved injection of contrast medium. The brain tumors were predominantly hyperdense (28.6%) and isodense (17.9%) pre-PDC, with regular contours (90%) and significant enhancement for hyperdense post-PDC masses and varying degrees of intensity for isodense masses. The tumors found were mostly benign (93.33%), consisting of glial cell tumors (35.7%), meningiomas(21.4%) and cysts (20%). Only 6.66% of tumours appeared to be malignant, essentially metastases and lymphomas. The tumors occupied mainly the supratentorial stage to a significant extent, with 76.66% precisely in the frontal lobe (28.6%), exerting a mass effect in 57.12%, particularly on adjacent brain parenchyma (28.6%). By comparing clinical data with CT scan findings, we were able to identify headaches and motor disorders as criteria that might suggest a brain tumor.

Conclusion : Cerebral tumors occur mainly in children and young adults, and are predominantly male. On CT, they appear as masses, mostly of solid density, hyperdense and mostly enhancing after PDC injection; the most frequent CT findings are meningiomas, arachnoid cysts and astrocytomas.
