“…31 Abdominal CT can detect the location and morphological characteristics of a cyst along with less dense intraluminal material in a dilated bile duct. 35 Cyst wall discontinuity, which is a direct sign of rupture, is present in only 75% of cases on abdominal CT. 31 Magnetic resonance cholangiopancreatography(MRCP) can facilitate the diagnosis of hydatid cyst complications as it can visualize daughter cysts, separation of the membranes, a dilated biliary tree, and hydatid cyst material in the biliary system. Endoscopic Retrograde Cholangiopancreatography (ERCP) is the gold standard in confirming rupture into the biliary tract, either by seeing the signs of radiolucent filling defect of daughter cyst in the dilated biliary ducts or a swollen ampulla of Vater with hydatid material protruding out.…”

Cholangiocarcinoma, an adenocarcinoma arising from the epithelium of biliary ducts, is considered the second most common hepatic malignancy after hepatocellular carcinoma with increasing incidence over the past 3 decades. Many imaging modalities with correlation to clinical presentation are used for the diagnosis and staging of cholangiocarcinoma. However, the diagnosis of cholangiocarcinoma is still challenging due to the presence of some benign and malignant conditions that mimic the clinical presentation and radiological findings of this disease. One of those mimics is the condition of intrabiliary hydatid cyst rupture which can cause biliary obstructive symptoms over weeks with radiological findings that may be indistinguishable from those of cholangiocarcinoma and specifically klatskin tumor when found at the bifurcation of the common hepatic duct. In such a confusing situation, the correct preoperative diagnosis and potential treatment of the disease could both be made possible using Endoscopic Retrograde Cholangiopancreatography avoiding unrequired surgical interventions.

“…mentioned that “In geographical areas endemic for hydatid disease, cyst rapture into the bile ducts should be included in the differential diagnosis even in seronegative cases, although it is not typical for hydatid cyst to be found as a mass lesion in the liver on US in patients with right upper quadrant pain and jaundice. Detailed imaging by MRI/MRCP should be done” [1]. There are some points for discussion.…”

Background: Fat can be identified in numerous liver lesions, and usually is not a specific finding. Distinguishing between different kinds of fatty deposits is an important part of differential diagnosis. Magnetic Resonance Imaging (MRI) is superior to other imaging techniques because it allows distinguishing intracellular from macroscopic fat. Discussion: Intracellular lipid may be found in focal hepatic steatosis, hepatic adenoma, hepatocellular carcinoma and, less commonly, in focal nodular hyperplasia as well as regenerative and dysplastic nodules. Macroscopic fat is seen in angiomyolipoma, lipoma, metastases from fatcontaining neoplasms, primary or metastatic liposarcoma, hydatid cyst, pseudolipoma of the Glisson capsule, pericaval fat collection, lipopeliosis, hepatic teratoma, focal hepatic extramedullary haematopoiesis and adrenal rest tumour. Conclusion: Liver nodules should be characterised with regard to underlying liver condition, MRI characteristics and contrast enhancement pattern, including hepatobiliary phase. In many cases, identification of fatty content may help narrowing the differential diagnosis.
