The aims of this study are To evaluate the CT features of incidental breast lesions on chest CT and subsequently suggest useful criteria for referral to a specialized breast unit.

Enhanced chest CT examination reports containing the key word 'breast' well be reviewed retrospectively. Patients who had incidental breast lesion and were referred to a specialized breast unit and then underwent pathological confirmation well be included. Finally, 100 patients well be enrolled. Two radiologists well evaluate lesion characteristics including; size, shape, margins and enhancement. The correlations between the CT features and pathologies well be evaluated and the diagnostic accuracy of CT features in various combinations well be assessed.

Inclusion Criteria:

• Inclusion criteria are patients who ex hibited incidental breast lesion(s) on enhanced chest CT and were referred to a specialized breast unit for assessment and then underwent pathological confirmation.

Exclusion Criteria:

• -Patients with known breast dis ease.
• Previous history of breast cancer or breast surgery.
• Patients who had undergone only non-enhanced CT examination.

Adult female

adult female patients who underwent enhanced CT chest that incidentally revealed breast lesion(s) then referred to a specialized breast centre and had histopathological diagnosis.
