The aim.of this case report is to raise awareness about the use of 3-Dim.ntional Com.uted Tom.graphy (3D-CT) virtual reality im.ging as a routine pre-operative tool for evaluation of unusual anatom. such as Situs Inversus Totalis (SIT). We present a case of presum.d lung cancer in a 58 years old lady with SIT successfully treated by VATS lobectom. via an anterior approach. She presented with an incidental solitary pulm.nary nodule in her right lower lobe, which had m.derate FDG uptake on the PET scan. The nodule was too deep to perm.t safe wedge biopsy, due to proxim.ty of a large pulm.nary arterial branch. 3D-CT im.ges were invaluable in pre-operative assessm.nt of the anatom. and were the key to safe com.letion of right VATS lower lobectom.. Sectioning the lung after retrieval of the specim.n suggested a chondroid ham.rtom.;therefore, system.c nodal dissection (SND) was not contem.lated. The final histology confirm.d the diagnosis of chondroid ham.rtom.. In an unusual anatom. such as SIT, 3D-CT allows construction of virtual reality m.dels that can be viewed and m.nipulated before and during the operation to understand the anatom. better, highlight caveats around target structures and enable localisation of lesions unlikely to be palpated intra-operatively.
