Abstract
The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Major changes include subdividing acute fluid collections into "acute peripancreatic fluid collection" and "acute post-necrotic pancreatic/peripancreatic fluid collection (acute necrotic collection)" based on the presence of necrotic debris. Delayed fluid collections have been similarly subdivided into "pseudocyst" and "walled of pancreatic necrosis". Appropriate use of the new terms describing the fluid collections is important for management decision-making in patients with acute pancreatitis. The purpose of this review article is to present an overview of complications of the acute pancreatitis with emphasis on their prognostic significance and impact on clinical management and to clarify confusing terminology for pancreatic fluid collections.

Abstract
Acute pancreatitis is an acute inflammatory disease of the pancreas that may also involve surrounding tissues or remote organs. The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Generally, imaging is recommended to confirm the clinical diagnosis, investigate the etiology, and grade the extend and severity of the acute pancreatitis. Ultrasound is the first-line imaging modality in most centers for the confirmation of the diagnosis of acute pancreatitis and the ruling out of other causes of acute abdomen, but it has limitations in the acute clinical setting. Computed tomography not only establishes the diagnosis of acute pancreatitis, but also enables to stage severity of the disease. Magnetic resonance imaging has earned an ever more important role in the diagnosis of acute pancreatitis. It is especially useful for imaging of patients with iodine allergies, characterizing collections and assessment of an abnormal or disconnected pancreatic duct. The purpose of this review article is to present an overview of the acute pancreatitis, clarify confusing terminology, underline the role of ultrasound, computed tomography and magnetic resonance imaging according to the proper clinical context and compare the advantages and limitations of each modality.

Abstract
Ectopic production of corticotropin-releasing hormone (CRH) by a pheochromocytoma is an infrequent cause of Cushing's syndrome. We report the case of a 43-year-old man with Cushing's syndrome due to a CRH-producing adrenal pheochromocytoma. The patient had clinical and biochemical evidence of hypercortisolism in conjunction with high ACTH levels and non-suppressible serum cortisol levels on low-dose and high-dose dexamethasone suppression testing. In addition to these clinical features of one month's duration, the patient developed symptoms of pheochromocytoma including headache, hypertension that was resistant to conventional therapy and excessive sweating. Biochemical testing confirmed elevated 24-hour urinary catecholamines and metabolites. Abdominal CT revealed a 4.5 x 4 x 3.5 cm mass in the left adrenal gland. He underwent elective left adrenalectomy. Light microscopic and immunochemical studies revealed a pheochromocytoma that contained immunoreactive CRH and was negative for ACTH. Plasma ACTH and dexamethasone supression tests normalized after surgery. This is an unusual case of a CRH-secreting pheochromocytoma. This was complicated by renal infarction, illustrating further the complexity of Cushing's syndrome in a patient with pheochromocytoma caused by CRH hypersecretion.

Abstract
Cutaneous T-cell lymphoma is a term used for mycosis fungoides and Sézary syndrome, the distinct clinical entities where the skin is the primary organ of involvement. Sézary syndrome is the leukemic variant of mycosis fungoides, presenting with generalized erythroderma, lymphadenopathy, and atypical cells (the Sézary cells) in the peripheral blood and bone marrow. The dissemination of cutaneous T-cell lymphoma may occur with no exception of the organs; however, no prior report exists about the Sézary syndrome secondarily involving the breasts. We report the clinical and radiological findings of bilateral breast involvement in a case of Sézary syndrome.

Abstract
PURPOSE Of the various methods of hemodynamic studies performed to evaluate erectile dysfunction penile color Doppler ultrasound is currently considered the best. However, intracavernous injection is invasive and has adverse effects, such as prolonged erection. We evaluated whether sildenafil may be used as a substitute for intracavernous agents when assessing impotence on color Doppler ultrasound. MATERIALS AND METHODS A total of 42 patients with erectile dysfunction underwent color Doppler ultrasound before and after intracavernous injection of 60 mg. papaverine with genital and audiovisual sexual stimulation. Peak flow and end diastolic velocity were measured in the recorded waveforms obtained 0, 1, 5, 10 and 20 minutes after injection. The patients also underwent color Doppler ultrasound after a 50 mg. oral dose of sildenafil with genital and audiovisual sexual stimulation not before 3 days after the papaverine study. The same parameters were measured at 30, 45, 60, 75 and 90 minutes, and compared with the values obtained after papaverine injection. RESULTS Mean peak flow velocity significantly increased after oral sildenafil starting at 30 minutes and achieving a maximum value at 60 minutes. There were no significant differences in the 2 methods in mean peak velocity 1, 5, 10 and 20 minutes after papaverine injection, and 30, 45, 60, 75 and 90 minutes after oral sildenafil administration. Penile color Doppler ultrasound with intracavernous papaverine injection is accepted as the gold standard but color Doppler ultrasound with sildenafil has 90% sensitivity and 100% selectivity for demonstrating arterial insufficiency. Due to prolonged erection 5 patients (11.9%) in the papaverine group required pharmacological detumescence by intracavernous injection. No adverse effects of sildenafil were observed. CONCLUSIONS Sildenafil administration achieved increased peak flow velocity comparable to that after intracavernous papaverine injection. With no prolonged erection sildenafil emerges as a safer alternative compared to more invasive intracavernous injection.

Abstract
Hereditary hemorrhagic telangiectasia, or Osler-Rendu-Weber disease, is an autosomal dominant disorder in which a variety of vascular dysplasias occur throughout the organ systems. We report the gray-scale and color Doppler sonographic findings in a case of hereditary hemorrhagic telangiectasia. Gray-scale sonographic examination revealed massive splenomegaly, multiple dilated intrasplenic vascular structures (some with adjacent punctate calcifications), an aneurysmal dilatation of the splenic vein, dilated intrahepatic portal branches, and marked atrophy of the right hepatic lobe. Color Doppler sonography showed dilatation of the truncus coeliacus and high-velocity flow in the splenic artery. There were significant aliasing in the splenic hilum and an abnormal, arterialized flow in intrasplenic branches of the splenic vein. The splenic vein was massively enlarged with increased flow velocity and contained an isolated aneurysmal dilatation in the hilum. There were multiple serpiginous retroperitoneal collateral vessels, and the left gastric vein was dilated with hepatofugal flow. The patient had portal hypertension that developed secondary to the increased portal flow.

Abstract
A 21-year-old woman with tuberous sclerosis presented with abdominal distension and flank pain. Imaging studies, including CT and MR imaging, revealed bilateral renal mass lesions, containing fat and suggesting the diagnosis of tuberous sclerosis. However the imaging characteristics of one of these lesions differed from the others with no radiologically detectable fat tissue in this solid lesion suggesting renal cell carcinoma. Histopathological examination of this lesion in the left kidney revealed an angiomyolipoma within minimal fat tissue. The radiological diagnosis of angiomyolipomas with minimal fat tissue remains difficult and the differential diagnosis is discussed.

Abstract
We report the case of a 67-year-old diabetic man who presented 2 months after transurethral prostate surgery with impaired consciousness, urinary incontinence, and recurrent urinary tract infections that did not respond to antibiotic treatment. Sonographic findings suggested abscess formation (enlarged, heterogeneous epididymides and a central hypoechoic area in the head of the left epididymis). Aspirates obtained from sonographically guided needle biopsy were purulent. Staining showed budding yeast forms, and Candida albicans grew in culture. Systemic candidiasis was diagnosed. The patient underwent bilateral epididymo-orchiectomy, and pathologic analysis of resected specimens showed bilateral epididymal necrosis and disseminated abscess formation.
