Pancreatic congenital anomalies and their features on CT and MR imaging: a pictorial review.

OBJECTIVE: To review the congenital anomalies of the pancreas with their main clinical manifestations and key imaging findings on CT and MRI. BACKGROUND AND CLINICAL SIGNIFICANCE: Anomalies of pancreatic development are frequent and generally asymptomatic, but can mimic and predispose individuals to pancreatic or peripancreatic pathologies, such as pancreatitis or malignancy. Their correct diagnosis may help avoid unnecessary further investigations and procedures, or establish adequate treatment when they manifest clinically. Differentiating pancreatic congenital anomalies from their main radiological mimics constitutes a challenge for the radiologist and requires familiarity with key imaging findings. CONCLUSION: The imaging findings of CT and MRI are essential for the correct diagnosis of congenital pancreatic anomalies.

Costal Chondroid Tumors Mimicking Intraabdominal Masses: The Pivotal Role of Computed Tomography in Diagnosis.

Teaching Point: Costal chondroid tumors can mimic abdominal masses and, when located in the right hypochondrium, may suggest hepatic origin. Computed tomography is essential to determine their origin and nature and to guide appropriate treatment.
