We report a case of a radical resection of cT3a gallbladder cancer after neoadjuvant chemotherapy(NAC). A 68-year-old man was referred to our hospital with a chief complaint of right hypochondralgia.Imaging findings were consistent with acute cholecystitis with a stone at the neck of the gallbladder, and advanced gallbladder cancer with infiltration into segments 4 and 5 from the fundus of the gallbladder, Gfb, cT3a(liver), cN1(8a), cM0, cStage III B, was diagnosed on staging laparoscopy. The patient received 3 courses of GEM plus CDDP NAC.The response to the treatment included reduction of the main tumor by 35%, diminished accumulation of FDG at the 8a lymph node, and decrease in serum CA19-9, from 163 U/mL to 75 U/mL. Cholecystectomy with the gallbladder bed and regional lymphadenectomy were performed.The histologic examination revealed extensive necrosis and degeneration of cancer cells in the infiltrating lesions, and the therapeutic effect was judged as Grade I b.The patient has now survived for 11 months without recurrence.

Signet ring gallbladder carcinoma is a rare aggressive variant of mucinous adenocarcinoma with poor prognosis. Positron emission tomography/computed tomography (PET/CT) with Fluor18 deoxyglucose (F18-FDG) is a useful tool in the staging of gallbladder cancer. We report a 68 years old man with a surgically resected acute cholecystitis, whose biopsy was positive for signet ring cell gallbladder carcinoma. During surgery, locoregional lymph nodes, liver or peritoneal involvement were not detected. A PET/CT was performed for staging, finding multiple hypermetabolic lytic bone lesions. Percutaneous biopsy of a pelvis bone lesion, confirmed a metastasis of the tumor. In this case, the staging with PET/CT allowed the diagnosis of unsuspected bone metastases and was a useful tool for deciding the best site of biopsy for histologic confirmation.
