Computed tomography of the abdomen and pelvis in non-Hodgkin lymphoma.

The experience of one institution using abdominal computed tomography (CT) for staging and restaging of non-Hodgkin lymphoma (NHL) patients is reported. In 49% of abnormal examinations no significant difference in quantity of involved nodes between diffuse and nodular lymphomas appeared. High paraaortic, iliac, and mesenteric nodal sites were most commonly involved. At restaging examination, usually less extent of disease was found. Abdominal involvement could not be predicted from the presence of peripheral adenopathy. Computed tomography changed the staged during initial workup significantly in 14%. During restaging, CT detected unsuspected active disease in 43% and changed the clinical impression from limited to extensive involvement in 16%. Computed tomography proved to be useful in the management of NHL patients and is recommended as the primary imaging procedure in the abdomen in this disease.

[Pancreas tail pseudotumor--CT for the detection of position variants of the pancreas tail as a cause for pathologic findings in conventional radiographic and ultrasound studies].

Four cases are presented, in whom conventional radiography of the abdomen including tomography and ultrasound raised high suspicion of a left suprarenal tumor. Abdominal CT explained the finding in each case as being produced by a normal anatomic variation of the pancreatic tail, which was found in a paraspinal and suprarenal location. The statistical incidence of such a variation is discussed.

Gastroesophageal reflux--reassessment of the value of fluoroscopy based on manometric evaluation of the lower esophageal segment.

The value of fluoroscopic gastroesophageal reflux examination by barium swallow was assessed in 51 symptomatic patients. Using electronic esophageal manometry, these patients were divided in groups with frank reflux, intermittent reflux, and symptoms of other etiology. Although a high incidence between presence of an hiatal hernia and manometric reflux (0.86) was apparent, fluoroscopy was only able to identify 33% of patients suffering from reflux disease diagnosed on clinical grounds and by electronic manometry. It is concluded that the fluoroscopic test is insufficient to separate patients with reflux disease from those with similar symptoms of other etiology which may be done reliably by esophageal manometry. The role of fluoroscopy is limited to the morphological evaluation of the gastroesophageal junction.

CT of the pancreatic tail.

The location of the pancreatic tail varies and is confined only by the limits of the anterior pararenal space and the left kidney. The morphology of the pancreatic tail and its location relative to the upper pole of the left kidney, the body of the pancreas, and the splenic hilum were assessed by body computed tomography in 101 patients with normal kidneys and in 15 patients with either small or absent left kidneys. In 97% of normal patients, the pancreatic tail was located anterior or anterolateral to the left kidney. In 75% of patients with surgically or congenitally absent kidneys, the pancreatic tail lay dorsomedial, adjacent to the spine, and occupied, with bowel and spleen, the empty renal fossa. Variation in pancreatic tail location may be of diagnostic importance in patients suspected of having mass lesions in the left mid-abdomen.

Gadopentetate-enhanced magnetic resonance imaging with fat saturation in the evaluation of Morton's neuroma.

Morton's neuromas, though usually diagnosed clinically, can occasionally be problematic. When required, imaging may be performed via ultrasound or computed tomography, though the former can be quite operator-dependent, and the latter exposes the patient to ionizing radiation. Magnetic resonance imaging can be very helpful in certain clinical situations. This case report demonstrates the usefulness of gadopentetate-enhanced magnetic resonance imaging with fat saturation in the evaluation of interdigital neuromas.
