Introduction: carotid body tumors (CBT) are relatively frequent lesions encountered at high altitudes such as the Andean Region. A correct preoperative diagnosis is essential for surgical planning and performance. For this reason, we have reviewed our experience in the diagnosis of these tumors. Materials and methods: between 1980 and June 2008, 160 CBT were diagnosed. One hundred and thirty-eight underwent surgery, 4 are waiting surgery and 18 were not operated for age, medical conditions or patient refusal. We have reviewed retrospectively the modalities of diagnosis in our patients. Results: among 138 operated tumors, a correct diagnosis was done in 127 cases (92%). The preoperative diagnosis of the remaining 11 patients was unspecified benign tumor in 6 and neck lymph node in 5. The imaging methods performed by different radiologists were conventional ultrasound, color Doppler ultrasound, carotid angiography, axial tomography, magnetic resonance, angioresonance and angiotomography. Most patients had more than one image study performed. Review of radiologic reports revealed a correct diagnosis in all carotid angiographies, magnetic resonance and angiotomography studies. Conclusions: clinical suspicion and current imaging techniques allow a correct diagnosis in practically all cases of CBT.
