Radiographs and CT imaging revealed lumbar degenerative kyphoscoliosis (Fig. 1A, B). The patient underwent XLIF at four disc levels, as well as posterior decompression and fixation (Fig. 1C, D).
(A) A picture obtained 3 months following surgery showing the bulging mass (arrows) in the anterolateral abdominal wall, close to the lateral surgical incision (arrowheads).. (B) A picture obtained 1 year following surgery showing the natural disappearance of the mass.

At 3 months following surgery, the patient complained of left abdominal flank discomfort, and bulging was observed near the skin incision of XLIF (Fig. 2A). We continued periodical observation, and it naturally disappeared at 1 year following surgery (Fig. 2B).
(A) An axial computed tomography image showing the thinned abdominal wall muscles at 3 months following surgery. There was no abdominal wall defect or hernia. There was abdominal wall bulging due to the abdominal contents.. (B) An axial computed tomography image showing the symmetrical abdominal wall with recovery of the muscle thickness.

The left abdominal wall muscles were thinned and had asymmetrical thickness in comparison with the right abdominal wall (Fig. 3A). Abdominal CT at 1 year following surgery confirmed a symmetrical abdominal wall and that the muscles had recovered to an almost normal thickness (Fig. 3B).
