(A) CT revealed a 10 x 17 mm space-occupying lesion (red arrow) in the hepatic hilum with an unclear boundary. (B) Tumor (red arrow) showed obvious enhancement. (C) Postoperative left residual volume was estimated to be only 27.6%.

Abdominal enhanced CT scan (Figure 1A) revealed a 10 x 17 mm mass in the hepatic hilum with an unclear boundary. In the arterial phase (Figure 1B), the mass showed obvious enhancement. Furthermore, the postoperative left residual liver volume (RLV) was estimated to be only 27.6% (Figure 1C).
(A) Abdominal CT 1 month later revealing an improvement in hepatic duct dilation (the red arrow designates the tumor). (B) Residual liver volume (RLV) increased up to 55.57%. (C) MRCP indicating a space-occupying lesion (red arrow) at the porta hepatitis, involving the cystic duct.

AST 256 U/L, ALP 188 U/L, gamma-GT 209 U/L), while bilirubin and tumor markers were all within the normal range. A contrast-enhanced CT (Figure 2A) of the abdomen revealed improvement in the dilation of the hepatic duct, while the volume of the left hepatic liver had increased by 55.57% (Figure 2B). Magnetic resonance cholangiopancreatography (MRCP) (Figure 2C) indicated an irregular shadow at the porta hepatitis with a vague boundary and involving the cystic duct.
(A) Intraoperative findings revealing an atrophied gallbladder, with a hardened texture (the red arrow points out the tumor). (B) Grayish-white nodule (pointed by the red arrow) seen at the neck of the gallbladder (represented by the red circle). (C) Low-magnification and (D) high-magnification pathological analysis showing spindle cells. (E) Immunohistochemical positivity of S-100.

The gallbladder had atrophied with a hardened texture (Figure 3A). A nodule, 1.4 x 1.0 cm in size, with a grayish-whitcross-sectionon (Figure 3B), was seen at the neck of the gallbladder. Pathological analysis and immunohistochemistry validated the diagnosis of traumatic neuroma through spindle cells (Figure 3C) and S-100 positivity (Figure 3D).
