Accessory grooves on the diaphragmatic surface of the liver: A cadaveric study

Introduction: Usually liver does not possess any grooves on its diaphragmatic surface, but there are reports on the presence of grooves on this surface. Aim: The present study was conducted to study the gross features of diaphragmatic surface of the liver and document the presence of any grooves on it and also to correlate our study with the previous studies. Materials and Methods: Ninety seven formalin embalmed livers stored in 10% formaldehyde were observed for the presence of grooves on diaphragmatic surface. Results: Fifteen (15.46%) livers had at least one groove on the diaphragmatic surface. Left lobe did not reveal the presence of any abnormal grooves. Presence of a single groove was observed in six (6.18%) livers; Double grooves were found in five (5.15%) livers; Triple grooves were found in three (3.09%) livers and four grooves were found in one (1.03%) liver. The deepest among all the grooves was measured 1.5 cm. Conclusion: The knowledge of these grooves is of importance to radiologists and surgeons during their routine procedures.
