Annular pancreas (AP) is a rare congenital anomaly, usually present in childhood, with symptoms due to duodenal obstruction; however, this condition can manifest in adulthood with abdominal pain, pancreatitis and pancreatic head mass. The authors present a case of AP observed in a 22-year-old patient that presented an unusual dual-phase clinical manifestation of duodenal obstruction in infancy that was treated by a duodenojejunostomy, and abdominal pain due to chronic pancreatitis in the adult age. MRI with cholangiopancreatography played a decisive role in achieving the correct diagnosis. The patient was treated by a pylorus-preserving Whipple procedure, with resection of the previous duodenojejunostomy. Pancreatic changes characteristic of chronic pancreatitis were demonstrated both in the AP and in the resected pancreatic segment. A marked biliopancreatic ductal anomaly not previously described in the literature was demonstrated by radiologic examination of the surgical specimen. The pathogenesis of AP, the importance of its association with benign and malignant pancreatic disease and the treatment alternatives are discussed by the authors.

We report a case of a 30-year-old patient with anomalous pancreaticobiliary junction (APBJ) that has not been described before. The patient had a clinical history of recurrent attacks of pancreatitis, cholangitis and cholecystitis that were confirmed by abnormal laboratory values. Endoscopic retrograde cholangiopancreatography revealed a 20 mm long junction of choledoc and pancreatic duct, and uncinate process draining into the minor papilla. On MR cholangiopancreatography, strictures at the junction of hepatic duct, increased gallbladder wall thickness and intraductal stone in the pancreatic duct were demonstrated as complementary findings. Other MRI findings included decreased signal intensity of the pancreas consistent with fibrosis from past pancreatitis attacks and atrophy of the left liver lobe.

The use of high frequency (7-12 MHz) transducers on state of the art US units equipped with Doppler imaging provides excellent evaluation of the pediatric pancreas that compares to other cross-sectional imaging techniques. The availability of multidetector CT imaging reduces the need for sedation but requires additional review of the indications and protocols to avoid unnecessary radiation exposure. Evaluation of pancreatitis and tumors remains the main indication. Advances in MR imaging and MRCP has lead to very good results in children. Storage diseases of the pancreas can be diagnosed at MRI. The length of the examinations, the need for sedation and the limited spatial resolution remain the main pitfalls of MR imaging of the pancreas in pediatric patients.

A 73-year-old woman had experienced dry mouth and swellings of both upper eyelids from 1998. In October 2003, she also developed bilateral submandibular swellings, and was diagnosed with diabetes mellitus and prescribed antidiabetic medication. She consulted our hospital in the summer of 2004 due to the exacerbation of eyelid swelling, and was admitted in October 2004. Keratoconjunctivitis sicca was not present. CT and MRI of the head showed bilateral enlargement of the lacrimal and submandibular glands. Serological investigations revealed hypergammaglobulinemia, but as antinuclear antibody and anti-SS-A antibody were absent, further investigation was performed. Serum concentrations of IgG4 were elevated and biopsy of the minor salivary gland revealed a severe infiltration of IgG4-positive plasmacytes. The patient was therefore diagnosed with Mikulicz's disease. Abdominal CT demonstrated diffuse pancreatic swelling, and endoscopic retrograde cholangio-pancreatography revealed stricture of the common bile duct and main pancreatic duct, suggesting the complication of autoimmune pancreatitis. Treatment was commenced with 40 mg/day of prednisolone. This resulted in rapid resolution of the lacrimal and submandibular gland swellings and recovery of salivary gland function. Diffuse swelling of the pancreas and stricture of the common bile duct and main pancreatic duct also improved, and endogenous insulin secretion increased. Both Mikulicz's disease and autoimmune pancreatitis presented with elevated serum IgG4 and infiltration of IgG4-expressing plasma cells into the glandular tissues. We recently proposed the new diagnostic entity of "IgG4-related plasmacytic exocrinopathy"; however, if diabetes mellitus in autoimmune pancreatitis was caused by direct dysfunction of pancreatic cells, we must reconsider this pathogenesis and consider a wider concept including exocrine as well as endocrine glands. This case, in which both types of glands were affected, is therefore of considerable interest.

The pancreas develops from ventral and the dorsal buds, which undergo fusion. Failure to fuse results in pancreas divisum, which is defined by separate pancreatic ductal systems draining into the duodenum. Risk of developing pancreatitis is increased in pancreas divisum because of insufficient drainage. MR cholangiopancreatography (MRCP) is the technique of choice for detecting pancreas divisum non-invasively. Annular pancreas is the result of incomplete rotation of the pancreatic bud around the duodenum with the persistence of parenchyma or a fibrous band encircling (and sometimes stenosing) the duodenum. Acute pancreatitis is usually caused by bile duct stones or alcohol abuse. The Atlanta classification differentiates between mild acute and severe acute pancreatitis associated with organ failure and/or local complications such as necrosis, abscess or pseudocyst. Contrast-enhanced multi-detector row CT is the method of choice to assess the extent of disease. Balthazar et al.'s CT severity index assesses the risk of mortality and morbidity. In acute pancreatitis, the role of MRCP is mainly limited to finding bile duct stones in patients with suspected biliary pancreatitis. Chronic pancreatitis results in relentless and irreversible loss of exocrine (and sometimes endocrine) function of the pancreas. MDCT even shows subtle calcifications. MRCP is the method of choice for non-invasive assessment of the duct. Inflammatory pseudotumor in chronic pancreatitis and groove pancreatitis are difficult to differentiate from pancreatic cancer. In these cases, multiple imaging methods such as MDCT, MRI and endosonography including biopsy may be used to make a diagnosis.

Advanced disease, defined as vascular invasion or invasion into adjacent organs, in pancreatic ductal adenocarcinoma still remains a major diagnostic and therapeutic challenge. In most cases, only exploratory laparotomy will ultimately ensure surgical resectibility. A physician is ill-advised to make any decision regarding palliation relying on CT-scan, MRI, ultrasonography or angiography, since vascular invasion is difficult to diagnose because of peritumoral pancreatitis mimicking vascular invasion. Only in the case of complete vascular encasement of the mesenterico-portal axis or celiac trunk is a laparotomy unnecessary. If a T3 lesion is present, the patient will benefit greatly from R0 surgical resection, even if this includes en bloc resections of the transverse colon, or the portal vein, which can be reconstructed without vascular grafting in most cases. In the presence of distant metastases only palliative treatment is useful. If liver metastases are identified pre-operatively, palliation should include endoscopic common bile duct stenting in the presence of icterus, or endoscopic duodenal stenting in the case of percutaneous endoscopic gastrostomy. If metastases are found during exploratory laparotomy, surgical palliation should be considered (bilio-digestive anastomosis or gastro-enterostomy), since these procedures do not lead to a significantly longer hospital stay and are not associated with significant morbidity or mortality. Pain control can be ensured using morphine analogs, CT-guided sympathectomy or thoracoscopic sympathectomy. Currently, there is no answer as to which option offers the best pain control and quality of life. There is also an ongoing debate on the palliative Whipple's procedure, even in the event of single liver metastases, since this procedure is associated with limited mortality (well below 5% in high-volume centers) and ensures excellent pain control. This needs an individual assessment of risk and, furthermore, a detailed discussion with the patient. There are no studies in which resection has been performed as a standard procedure for palliation. This question should be answered in a multicenter randomized trial, otherwise the palliative Whipple's operation should still be considered experimental, since it is not likely to significantly prolong survival.

We present case report of primary hyperparathyroidism treated surgically as well as a review of literature concerning this subject. The disease of not well known etiology presents with elevated parathormon levels and hypercalcemia. Primary hyperparathyroidism which states 85% percent of all kinds of hyperparathyroidism is usually parathyroid adenoma, in 11-15% glandular hyperplasia and in 1-4% parathyroid cancer. Clinical symptoms are muscle weakness and fatigue, nephrolithiasis, occasionally peptic ulcers, pancreatitis, hypertension. Laboratory test reveal increased level of PTH, hypercalcemia, elevated alkaline phosphatase levels and decreased phosphorus levels. Diagnostic imaging techniques such as ultrasonography, MRI or CT have sensitivity about 52-75%. Highest sensitivity in localization of ectopic parathyroid adenoma has sestamibi scintigraphy with technetium-99. Skeleton x-rays show typical changes in distal parts of bones and osteopenia. Treatment of choice is surgical excision of adenoma. Normalization of PTH and calcium levels after surgery and improvement of renal, musculoskeletal and circulatory system function could be achieved in 95%. Most common complications are recurrent laryngeal nerve injury, hypo- or hyperparathyroidism, bleeding or stridor.

Choledocholithiasis is a not uncommon and potentially grave condition which requires a well-adapted approach. Echo endoscopy and biliary MRI have improved the ability to make the diagnosis non-invasively, but intraoperative cholangiography remains the most accurate study. A surgical approach permits simultaneous treatment of both choledocholithiasis and the associated cholecystolithiasis; laparoscopic common duct exploration has been more frequently performed through a laparoscopic approach in recent years, but this procedure requires specific equipment and surgical experience. In most circumstances, surgery should be preferred to endoscopic clearance of the common duct, but endoscopy may be preferred in the setting of severe cholangitis or pancreatitis. The importance of a systematic search for asymptomatic choledocholithiasis is once again emphasized.

Infected pseudocyst as a consequence of tropical pancreatitis presenting as psoas abscess is unusual. We report a 40-year-old man who presented with pain in the right lumbar region. CT and MRI of the abdomen revealed pancreatic pseudocysts with abscess formation in the psoas muscle and evidence of chronic calcific pancreatitis. He was managed by percutaneous drainage of the abscess along with antibiotics and other supportive measures.

Catecholamine-secreting metastatic carcinoid should be considered in differential diagnosis of malignant pheochromocytoma. Paroxysmal functioning or hormonally silent gastroenteropancreatic neuroendocrine tumors (GEP NETs) require repeat biochemical measurements and sensitive anatomic and functional imaging studies overlapping those for malignant pheochromocytoma. This report presents clinical, laboratory, and radiologic findings in a patient presenting with heart rate variability; vasoactive headaches reactive to ethanol, tyramine and tryptophan; labile blood pressure; diaphoresis; diarrhea; abdominal pain; unexplained pancreatitis; joint pain; and paroxysmal flushing with pallor. GI studies (including endoscopic ultrasound) and multiple imaging modalities (including 2D CT, MRI with gadolinium, [18]FDG PET/CT, [123I]MIBG, and SRS [111In]Octreotide [OctreoScan]) were not diagnostic. 24-h BP, Holter and 30-day cardiac event monitors plus urinary biochemical studies consistently suggested catecholamine-synthesizing NET. NIH plasma metanephrines studies and [6]-[18F]Fluorodopamine PET ruled out malignant pheochromocytoma (pheo). Repeated studies showed persistently abnormal GEP NET biomarkers and urinary catecholamines. Capsule endoscopy revealed suspicious submucosal lesions throughout the small intestine. Dual-phase 64-slice multidetector computed tomography (MDCT) with 3D volumetric reconstruction of the abdomen and pelvis revealed multiple diffuse liver metastases and three extrahepatic lesions consistent with metastatic carcinoid. In combination, intensive biochemical testing repeated over time, dual-phase 64-slice MDCT with 3D image reconstruction and volume-rendering (VR) technique, and advanced radionuclide imaging are required to detect NETs' sporadic or paroxysmal functioning, rule out extra-adrenal pheochromocytoma, and localize and characterize metastatic carcinoid. If pheochromocytoma is ruled out, yet symptoms and biochemical markers for catecholamine excess are present, then carcinoid and other amine-precursor-uptake decarboxylation (APUD) tumors must remain in the differential diagnosis.
