RT Journal Article SR Electronic T1 Partial breast resection for multifocal lower quadrant breast tumour using virtual reality JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e241608 DO 10.1136/bcr-2021-241608 VO 14 IS 3 A1 Laas, Enora A1 El Beheiry, Mohamed A1 Masson, Jean-Baptiste A1 Malhaire, Caroline YR 2021 UL http://casereports.bmj.com/content/14/3/e241608.abstract AB Oncoplastic surgery allows an increase in the number of indications for conservative breast cancer treatments. However, uncertainty as to whether it can be performed still exists in certain situations such as with multicentric or multifocal lesions, even when the breast volume can accommodate it. With the aid of a virtual reality software, DIVA, allowing the precise visualisation of tumours and breast volumes based entirely on the patient’s MRI, we report the ability to rapidly confirm and secure an indication for partial surgery of multiple lesions in a 31-year-old patient. With the described approach, the patient did not have to suffer significant disfigurement from cancerous breast surgery without compromising safety.
