Abstract
Background: Aim of this study was to evaluate morphologic criteria for diagnosis of locally recurrent head and neck tumors in helical CT. Methods: Retrospective study, 44 examinations with radiologically abnormal findings were re-read by two radiologists; findings were analysed and correlated with histological diagnosis and clinical findings. Results: 25 cases of local tumor recurrence were confirmed histologically. The accuracy of helical-CT inour preselected examinations for a local tumor recurrence was 93.5%, the specificity 83.3%. But 13/44 cases showed radiologically equivocal findings,among them 6 tumor recurrences. The most common characteristics of the 25 proven tumor recurrences were: contrast medium enhancement (96%), increasedvolume in comparison to previous examination (92%), inhomogenity (72%); however contrast medium-enhancement and increasing volume were also seen in 68.4% and 63.1% of the benign changes. Conclusion: Contrast medium enhancement and increasing volume are criteria with a high sensitivity but low specificity in predicting a local tumor recurrence in head and neck cancer.
