Medico-legal issues in breast imaging.
OBJECTIVE
To identify medico-legal issues that occur in the diagnosis and radiological management of breast disease and to propose measures to reduce the risk of patient complaints and legal action in breast radiology and diagnosis.


METHODS
Institutional review board approval was not applicable for this study. A retrospective study was undertaken and records of 120 medico-legal investigations over a 10 year period were examined. The reports were compiled by two consultant breast radiologists.


RESULTS
The mean age of the patients represented in this study was 48.3 years. The main complaint in this series was a delay in diagnosis (92%) followed by inappropriate or inadequate treatment (8%). 81% of cases were patients who had presented to the symptomatic clinic. The main presenting symptom was a palpable lump (65%). Substandard care was cited in 49/120 cases (41%). The mean average delay in diagnosis was 15.6 months. Of the cases cited as substandard care, 61% were considered the fault of the radiologist and 14% considered the fault of the breast surgeon. Of the cases where the radiologist was considered to be at fault, microcalcification was the most common mammographic sign to be missed or misinterpreted (12/26 cases, 46%).


CONCLUSIONS
The most common complaint in this series was delay in diagnosis with microcalcification being the main mammographic sign that was either not seen or misinterpreted by the radiologist. Clear and precise written protocols are recommended for all breast imaging practice to ensure that medico-legal investigations will be greatly reduced.
