The spectrum of cystic masses of the pancreas: imaging features and diagnostic difficulties.

Cystic masses of the pancreas comprise a diverse group of pathologic entities ranging from pseudocysts to cystic tumors. Although their presentations may be similar, the appropriate treatment and patient management can differ greatly. There is an overlap in radiologic features, but the clinical context and some imaging findings are useful in differentiating among these entities; the differential diagnosis could be considerably reduced and it is generally possible to reach the correct diagnosis.

[Recurrent Budd-Chiari syndrome as a complication of nocturnal paroxysmal hemoglobinuria].

Budd-Chiari syndrome is a frequent complication of nocturnal paroxysmal hemoglobinuria, histologic and angiographic study being fundamental for diagnosis. We emphasize the importance of ultrasonography and abdominal CAT as noninvasive methods of early diagnosis, and the value of ultrasonography in the follow-up of these patients. Radical therapy of the disease from onset is a determinant of the final prognosis of these patients, as well as early treatment of thrombosis with thrombolytics and/or anticoagulants.
