Thirty right hepatic arteries discovered among 137 celiomesenteric angiographies show the high frequency (22%) of this variation. Radiologic anatomy of the right hepatic artery was discussed; with the exception of one atheromatous stenosis, the pathologic findings of the right hepatic artery and its terminal branches illustrate the development of a regional disease (12 cases or 40%). This assumed pathology is divided half in pancreatic causes (neoplasm, pancreatitis, pseudocysts) and half in hepatobiliary causes (metastatic cancer of the liver, cancer of the hilus, cirrhosis, hydatid cyst, alveolar echinococcosis or angioma). Five times the surgical technic was modified because of the right hepatic artery. Since these observations were made, we are studying the consequences of this hepatic artery over surgical technics and the approach to the various segments of this artery.

Literature data and original clinical evidence are reviewed concerning diagnostic and treatment aspects of splenic artery aneurysms (SAA). Five cases of aneurysms of the splenic artery trunk in 4 females and 1 male aged 23-54 are described. There was a case of a false SAA due to previous abdominal trauma and consequent pancreatitis. In another case SAA combined with cavernous hepatic hemangioma. Portal hypertension resultant from hepatic cirrhosis was seen in 3 out of 5 SAA cases. Two patients underwent embolization of the artery trunk proximally from SAA, three patients--ligation of the splenic artery with removal of the SAA and the spleen. Current methods of investigation are believed capable of SAA diagnosis before fatal complications, with differential approach to SAA evaluation warranting definition of surgical treatment scope.

The investigation is concerned with developing a model for using blood serum from patients with hepatic tumors to induce the activity of a gamma-glutamyl transferase enzyme in homogenized bovine hepatic tissue culture. An immunoglobulin protein was found to be responsible for the effect. The technique under discussion (Patent No. 2027997) provides a means for differential diagnosis of hepatoma and liver metastasis, on the one hand, and cholecystitis, pancreatitis, hepatitis, echinococcosis and hemangioma of the liver, on the other. The effectiveness of the method was 94.7; sensitivity--90.8 and specificity--97.9%.

A transgenic mouse line carrying ornithine decarboxylase cDNA as the transgene under the control of a mouse mammary tumor virus long terminal repeat (MMTV LTR) promoter was generated in order to study whether ornithine decarboxylase transgene expression will have any physiological or pathological effect during the entire life of a transgenic mouse. The high frequency of infertile animals and the loss of pups made the breeding of homozygous mice unsuccessful. However, a colony of heterozygous transgenic mice was followed for 2 years. In adult heterozygous transgenic mice, ornithine decarboxylase activity was significantly increased in the testis, seminal vesicle and preputial gland when compared to non-transgenic controls. In contrast, ornithine decarboxylase activity was decreased in the kidney and prostate of transgenic mice. No significant changes in ornithine decarboxylase activity were found in the ovary and mammary gland and only moderate changes in ornithine decarboxylase activity were detected in the heart, brain, pancreas and lung. The most common abnormalities found in adult animals (12 males and 20 females) of the transgenic line were inflammatory processes, including pancreatitis, hepatitis, sialoadenitis and pyelonephritis. Spontaneous tumors were observed in eight animals, including two benign tumors (one dermatofibroma, one liver hemangioma) and six malignant tumors (one lymphoma, one intestinal and three mammary adenocarcinomas and one adenocarcinoma in the lung). No significant pathological changes were found in 17 nontransgenic controls.

There is a broad range of inflammatory, pseudotumoral, and benign lesions that may masquerade as pancreatic malignancies, often representing a challenge to the radiologist. Unawareness of these entities can lead to inadequate differential diagnoses or misdiagnosis, with important prognostic and therapeutic consequences. The purpose of this article is to revisit a spectrum of lesions, varying from common to exceedingly rare nonmalignant, that may mimic malignant pancreatic neoplasms on imaging, identifying relevant features that may contribute to reaching the correct diagnosis. Representative cases include focal fatty replacement, intrapancreatic accessory spleen, pancreatic lobulation, lipoma, autoimmune pancreatitis, focal pancreatitis, eosinophilic pancreatitis, groove pancreatitis, hemangioma, intrapancreatic aneurysm, tuberculosis, and Castleman's disease.

Few things in radiology are "pathognomonic" in their appearance or presentation. However, having an awareness of those findings which are specific to a certain entity is important when interpreting imaging studies. These classic findings can be identified with many imaging modalities, but no modality provides as many recognizable observations as an MRI. This results from the large variety of pulse sequences that provide high contrast resolution, prior to and following contrast administration. In this article, the most classically recognized abdominal findings are presented including the following: Liver: Cyst, hemangioma, focal nodular hyperplasia, hepatic adenoma, hemosiderosis, hepatocellular carcinoma. Spleen: Cyst, hemangioma, lymphangioma, hemosiderosis, Gandy-Gamna bodies. Biliary system: Biliary stones and choledocholithiasis, pneumobilia, choledochal cyst. Gallbladder: Adenomyomatosis, sludge, surgical clips in the gallbladder fossa. Pancreas: Pancreatic divisum, intraductal papillary mucinous neoplasm, pseudocyst, autoimmune pancreatitis, chronic pancreatitis, adenocarcinoma. Kidneys: Simple cyst, hemorrhagic cyst, renal sinus cyst, angiomyolipoma, solid mass.
