Mucinous cystic neoplasm of pancreas are relatively rare >95% occur in the body and tail of pancreas. Majority occur in young and middle aged female containing ovarian type subepithelial stroma. These tumors are either premalignant (MCN with low grade dysplasia) or (MCN with high grade dysplasia) or invasive carcinoma. Differential diagnosis includes pancreatic pseudocyst and pancreatic hydatid cyst. Investigations include ultrasonography (USG), Magnetic resonance imaging (MRI), Contrast enhanced computed tomography (CECT) supplemented by endoscopic USG with cyst fluid aspiration.

Hepatocyte Nodules

Tumor hemodynamics of carcinogenic hepatocytes nodules, that is, low grade dysplastic nodules, high grade dysplastic nodules, early hepatocellular carcinomas (HCCs), and progressed HCCs, change during multistep dedifferentiation of the nodules. Morphometric analyses of inflow vessels of these nodules indicate that the portal veins of carcinogenic hepatocyte nodules monotonically decrease whereas the arteries bitonically change, first decrease and then increase. Findings on imaging techniques depicting these changes in tumor blood inflows, especially intra-arterial contrast-enhanced computed tomography, closely related not only to the histological differentiation of the nodules but also to the outcomes of the nodules. Histological analyses of connections between the vessels within the tumors and those in the surrounding livers and findings on imaging techniques indicate that drainage vessels of HCC change from hepatic veins to hepatic sinusoids and then to portal veins during multistep hepatocarcinogenesis. Understanding of tumor hemodynamics through radio-pathological correlations will be helpful in drawing up therapeutic strategies for carcinogenic hepatocyte nodules arising in cirrhosis.

Pseudocyst Of The Pancreas

AbstractA mass lesion of the gastric cardia or fundus causing an alteration in the normal regular, translucent gastric fundal air shadow on a frontal erect chest radiograph is referred to as “the Kirklin sign.” Here we present “Pseudo-Kirklin sign” observed on the frontal radiograph of a 46-year-old male patient due to a soft tissue shadow/contour deformity of the fundal gas shadow caused by pseudocyst of the pancreas. We evaluated the patient using plain radiography, contrast enhanced computed tomography, magnetic resonance imaging, and endoscopic ultrasound (EUS) with the cyst drained under EUS guidance. So far only two cases of mediastinal pseudocysts have been drained successfully by EUS-guided aspiration.

Fetus in fetu is a rare condition associated with abnormal embryogenesis in a diamniotic, monochorionic pregnancy, wherein one of the fetus is enclosed within the body of another normally developing fetus. It should be differentiated from a teratoma because of the later’s malignant potential. Here we report a case of 2 months old girl child who presented with complaints of abdominal distension. USG showed a solid cystic retroperitoneal mass resembling an anencephalic fetus. Contrast enhanced Computed tomography (CT) showed similar findings with visualization of bones resembling femur, sacrum and vertebrae. Findings were correlated with MRI and post-op pathology. The preoperative diagnosis of FIF is based on the observation of vertebral column or limbs in a mass on imaging modalities and our case meets the required criteria.

Multicystic biliary hamartoma (MCBH) is an extremely rare cystic lesion of the liver. A 37-year old male patient was admitted to our hospital for incidentally discovered hepatic cystic lesions on abdominal ultrasonography. Abdominal contrast-enhanced computed tomography (CT) showed a multilocular cystic lesion in the segment VI, with mild enhancement in the septae and peripheral wall within the lesion. Only alanine transaminase (ALT) and carbohydrate antigen 19–9 (CA19–9) increased slightly above normal value. Preoperative tests suggested possibility of a benign mucinous cystic neoplasm (MCN) or intraductal papillary neoplasm of the bile duct (IPNB). Laparoscopic complete resection of the lesion was performed. Histopathological examination showed numerous variably sized ductal structures surrounded by periductal glands and fibrous connective tissues containing small blood vessels and smooth muscle bundles. Immunohistochemical staining (IHC) revealed that dilated ducts were positive for cytokeratin CK19, characteristic for biliary tract. Histopathological findings confirmed diagnosis of multicystic biliary hamartoma (MCBH). No recurrence occurred during 6 months follow-up. In conclusion, MCBH should be differentiating from hepatic cystic lesion and could be resected laparoscopically safely.
