Mimicks of pancreatic malignancy in patients with chronic pancreatitis: correlation of computed tomography imaging features with histopathologic findings.

Differentiation of chronic pancreatitis and pancreatic carcinoma can be a clinical and radiologic dilemma. Several patients with chronic pancreatitis can undergo unnecessary major abdominal surgery for benign lesions. This pictorial review illustrates the computed tomographic findings and histopathologic features of lesions mimicking pancreatic neoplasm in patients with chronic pancreatitis. Several benign lesions can simulate pancreatic malignancy in patients with chronic pancreatitis. Knowledge of the computed tomographic appearance of these benign entities is important to prevent unnecessary surgeries.

Magnetic resonance imaging of maternal diseases causing acute abdominal pain during pregnancy: a pictorial review.

Evaluation of acute abdominal pain in a pregnant patient is a clinical challenge. In these patients, magnetic resonance imaging (MRI) can allow a systematic cross-sectional evaluation of the entire abdomen and can provide clinically useful information in a short enough time for emergent diagnosis. This pictorial essay demonstrates MRI findings of various maternal diseases that can present as acute abdominal pain in pregnant patients. Familiarity with these findings is important for the radiologist to make an accurate and prompt diagnosis.

Diabetes insipidus as a consequence of neurologic involvement in Behcet's syndrome.

OBJECTIVE: To describe a case of central diabetes insipidus that was associated with Behçet's syndrome. METHODS: We present a case report, including clinical, laboratory, and radiologic data. The pertinent literature is reviewed relative to diabetes insipidus and Behçet's syndrome, and a discussion about a possible association is presented. RESULTS: A 32-year-old man presented with diplopia and severe headaches and was found to have transverse sinus thrombosis. He reported having recurrent mouth and genital ulcers for 3 months before the current consultation. On the basis of the clinical picture, Behçet's syndrome was diagnosed. During hospitalization of the patient, polyuria and polydipsia developed, along with hypernatremia and hypotonic urine, indicative of diabetes insipidus. After desmopressin treatment was initiated, considerable improvement in clinical status and laboratory data was evident and persisted during follow-up. CONCLUSION: Behçet's syndrome, probably through vasculitic mechanisms, may result in central diabetes insipidus. This case report emphasizes that Behçet's syndrome should be considered in the differential diagnosis of diabetes insipidus.
