Introduction: parotid tumors are the most common tumors of the salivary glands. One of the most commonly used diagnostic methods to evaluate them is computed axial tomography, with or without contrast.
Objective: to describe the tomographic findings and diagnostic efficacy of computed axial tomography in patients with parotid gland tumors.
Methods: a descriptive cross-sectional study was carried out in 37 patients over 18 years of age at the Oncology Center of Vladimir Ilyich Lenin Hospital. All of them had lesions consistent with parotid tumors and cytological analysis results. The diagnostic correspondence of tomography and cytology was calculated. The ethical precepts of the research were met.
Results: 54.10 % were men, aged 60 to 79 years (45.90 %). Tumor images showed hyperdensity (81.10%), heterogeneous enhancement (83.80 %), and heterogeneous texture (83.80 %). Their sizes ranged from 2-4 cm (51.40 %). Malignant lesions predominated (89.20%). The tomography presented 93.95% sensitivity, 100.00 % specificity and 94.60 % diagnostic accuracy.
Conclusions: the majority of patients were male and over 60 years of age. The predominant tomographic findings were hyperdense tumors, with heterogeneous enhancement after intravenous contrast administration, sizes of 2-4 cm, and infiltrations in neighboring structures. The sensitivity and specificity of the imaging test were high, which determined its diagnostic validity. The research provided evidence of its efficacy in cases of tumoral conditions of the parotid glands. It is recommended to systematize tomographic findings and their characteristics in high-risk population and occupational groups.
