One pitfall in diagnosis is the variation in position that the above structures may assume normally or with malrotation. Meticulous technique is critical to either type of study in order to delineate these structures accurately. The use of too much or too little contrast material may render the study undiagnostic. Fig. 3. Examples of high gastrointestinal obstruction in newborns. a A double bubble appearance is present due to distention of the stomach and duodenum by gas. There is no gas distally.
In addition, accessory spleen and polysplenia should not be misdiagnosed as masses. Synchronous and equal enhancement of accessory spleen with the normal spleen is one clue to diagnosis. Patients with history of traumatic splenic rupture who have had a prior splenectomy are prime subjects to develop intra-abdominal splenosis. This condition results in implantation of splenic tissues on the peritoneal surfaces, which grow and mimic small nodules or masses. If the patient develops malignancy at a later age, splenosis should not be mistaken for metastases (Fig.
Mortele are more prominent upon inspiration or in patients with emphysema. The diaphragmatic crura are ligamentous bands that are tendinous at origin. The right crus is longer and larger and often more lobular than the left side. On axial images of CT or MR, thickened areas of the crura can be mistaken for lymphadenopathy or even an adrenal nodule. The caudate lobe of the liver may be divided in its inferior part into the medial papillary process and the lateral caudate process. If prominent, papillary process may appear similar to an enlarged node at the porta hepatis or simulates a mass in the head of the pancreas [1, 6].
