[Diagnosis of tumors of the small intestine with the aid of CT contrast enema. Sellink CT technique evaluated in 63 patients]. / Diagnostik von Dünndarmtumoren mit Hilfe des CT-Enteroklysma. Die CT--Sellink ausgewertet bei 63 Patienten.

PURPOSE: Aim of the study was to compare the visualisation of small bowel tumours particularly lymphoma of the small bowel by enteroclysma, computed tomography (CT) and computed tomography following enteroclysma. METHODS: We examined 97 examinations in 63 patients. Non Hodgkin's Lymphoma was the primary malignancy in 44 patients, metastasis of different malignancies in 8 patients, primary malignancies of the small intestine in 5 patients, mesenteric tumours in 4 patients and postoperative stricture in another 2 patients. CT following enteroclysma (CT Sellink) was performed as helical CT in 55 patients and as incremental CT in 42 patients. Examinations were evaluated by two radiologists. Evaluation criteria were small bowel distension, perceptibility of details and topographic correlation. RESULTS: Manifestations of lymphoma were found in 32 patients, infiltration of bowel wall in 12 patients. In three patients metastases of melanoma were found. In three patients the suspicion for small bowel tumours was not verified in CT Sellink. The perceptibility of details was evaluated as ameliorated in 45.5% of examinations over all. CONCLUSIONS: CT Sellink offers remarkable advantages in the diagnosis of small bowel tumours compared with enteroclysma and "conventional" computed tomography under intra-venous and oral contrast media. CT Sellink was feasible over a time of 7 years now in clinical praxis. This examination represents an optimized standard in small intestine examination.

[BALTOMA--long-term follow-up]. / BALTOMe--ein Langzeitverlauf.

PURPOSE: The purpose of this work was to describe the findings and the long term follow up of pathologically confirmed bronchus-associated lymphoid tissue lymphoma (BALTOMA) in 6 patients. METHODS: CT examinations and conventional radiological examinations were reviewed and compared to describe typical radiological findings and patterns of pulmonary manifestations. It were described the number of lesions and characteristics like presence of airspace consolidation, ground-glass attenuation, bubble-like radiolucencies, air bronchogram, bronchial dilatation, Infiltration and the long term behaviour of the manifestations. RESULTS: Lesions with a positive air bronchogram, no infiltration of extrapulmonary tissue or extrapulmonary manifestations were revealed as typical findings. Only a slow or no progression of disease was shown in most patients over a term of up to twelve years. CONCLUSIONS: The lymphoma of the bronchus-associated lymphoid tissue of the lung is a rare tumor. A positive air bronchogram, a multiplicity of disease, bilateral lesions, a fibrotic transformation of the lung tissue and no growth or only a slow groth over al long term of observation are typical radiological findings.
