USGFINDINGS -MALIGNANCY
üMural thickening
ücalcification
ümass protruding into lumen
üfixed mass in GB
üloss of interface between gband liver
üdirect liver infiltration

ØPolyp over 1 cm in diameter -invasive
§FNAC (cholesterolosis/GBC)
§Adenoma/GBC –less accurate
§CT/MRI required
ØPolyp less than 1 cm
§adenoma/ papilloma/ cholesterosis/ GBC less likely
COLOR DOPPLER -VASCULARITY
•pulsatile flow -seen in most cases
•continuous flow pattern
•Doppler sensitivity is mandatory for diagnosis of GBC in stage T 1 a

üIncidentallydiagnosedGBCfollowingsimple

CECT
•CT is more useful than US for detecting lymph node
involvement, adjacent organ invasion, and distant
metastasis.
INDICATIONS
•USGdetectedgallbladderlesionthatmay
representGBC
•IncidentallydiagnosedGBCfollowingsimple
cholecystectomy.

CT FINDINGS -GBC
üPolypoid mass protruding into the lumen/ filling it
üFocal or diffuse thickening of gallbladder wall.
üMass in gallbladder fossa
üLiver invasion
üNodal involvement
üDistant metastasis
GBC vscholecystitis
Higherfrequencyof

•moreextensivewallthickness
•focalirregularity
•lessdistension

LIMITATIONS
•Less helpful in differentiating between benign and
malignant polyps.
Computed tomography scan showing
gallbladder cancer with invasion into the
duodenum and liver parenchyma.
Computed tomography scan showing
gallbladder mass with local invasion into
portal vein (arrow).

MRI
•USG findings are confirmed on MRI.
MRI/MRCP –differentiate benign from malignant GB
lesions
•GBC is typically T1 hypointenseand T2 hyperintense
compared with the surrounding liver parenchyma.

COMPLETING THE STAGING EVALUATION

•Serumtumormarkers–CEAorCA19-9areoftenelevated-
lackspecificityandsensitivity.
If a tumor marker is found to be elevated preoperatively, serial assay after
resection might aid in the diagnosis of persistent or recurrent disease.

T 1 Tumourinvades the lamina propriaor muscular layer
T1a Tumourinvades the lamina propria
T1b Tumour invades the muscular layer
T 2 Tumourinvades the perimuscularconnective tissue
T2 aTumourinvades the peri-muscular tissue on the peritoneal side
without involvement of the serosa(visceral peritoneum).
T2 bTumour invades the perimusculartissue on the hepatic side
without extension into the liver.
T3 Tumour perforatesthe serosa (visceral peritoneum) and/or
directly invades the liver and/or one other adjacent organ or
structures

invades two or more extra hepatic organs or structures.
