Primary intestinal lymphangiectasia in three dogs: a morphological and immunopathological investigation.

Morphological and immunological findings of three dogs with primary lymphangiectasia are described and compared with three normal dogs. Scanning electron microscopy showed distended and fused intestinal villi in dogs with intestinal lymphangiectasia, and morphometric evaluation revealed deeper crypts in the small intestine of dogs with intestinal lymphangiectasia. Although plasma cells of all classes were diminished in the cranial parts of the small intestine, there was an absolute and relative increase of immunoglobulin G-containing plasma cells in the caudal small intestine in dogs with intestinal lymphangiectasia.

Intestinal lymphangiectasia with lipogranulomatous lymphangitis in a dog.

Intestinal lymphangiectasia with lipogranulomatous lymphangitis was diagnosed at necropsy in a 6.5-year-old Maltese dog that had a history of bouts of vomiting, abdominal distention, and diarrhea. The condition was attributed to trauma to the pleural and peritoneal cavities received from bite wounds inflicted one year previously.

[Electron microscopy of the intestinal mucosa in a case of lymphangiectasis].

The morphology of the intestinal mucosa was reviewed using light microscopy and transmission electron microscopy from a two year-old male patient with protein losing primary intestinal lyphangiectasis. Diagnostic studies ruled out recognized forms of secondary intestinal lymphangiectasia (e.g cardiac, hepatic, renal diseases or lymphoreticular cancer). Furthermore, certain features distinguish this patient from the secondary type: decreased immunoglobulin and albumin levels, lymphocytopenia, chylous ascitis and delated lymphatics on small-bowel biopsy.

Intestinal lymphangiectasia: evaluation by CT and scintigraphy.

Intestinal lymphangiectasia caused severe diarrhea and generalized edema in a 40-year-old man. The diagnosis was established by clinical, laboratory, and duodenal biopsy findings. The abnormalities detected on computed tomography (CT) and scintigraphy using 99mTc human serum albumin are herein described and pertinent literature is briefly reviewed.

Lymphangiectasia of the small intestine: description and pathophysiology of the roentgenographic signs.

Waldmann in 1961 redefined primary protein-losing gastroenteropathy and renamed the condition "lymphangiectasia". This abnormality, usually seen in infancy, is characterized by enlargement of folds and signs of hypersecretion in the small bowel. Enlargement of folds occurs secondary to edema of the valvulvae conniventes and lymphatic dilatation. Hypersecretion may be the result of rupture of dilated lymphatics or transudation of protein across an intact capillary epithelium. The clinical, roentgenographic, and pathologic findings are described. The pathophysiology of this condition is discussed.

Endoscopic appearance and significance of functional lymphangiectasia of the duodenal mucosa.

Intestinal lymphangiectasia is found in a wide variety of pathologic conditions. Functional lymphangiectasia has not been well characterized. We report 20 patients followed for 9 to 55 months (mean 30 months) after incidental detection at endoscopy of lymphangiectasia. Our study indicates that functional lymphangiectasia is not pathologic and does not warrant repeat endoscopy in the absence of other clinical indications.

Congenital intestinal lymphangiectasia: CT demonstration in a young child.

There have been few reports of the CT findings of intestinal lymphangiectasia in adults, and no CT descriptions have been reported in the literature in children. We describe the CT appearance of a biopsy-proven case of primary small intestinal lymphangiectasia in a 3-year-old boy, and we will review the limited literature on the CT findings in this disorder in adults.

Functional lymphangiectasia of the duodenal mucosa.

Tiny millet-like prominent villi with dilated lymphatics may be part of a food-induced functional lymphangiectasia. Peroral olive oil load causes diffuse transient lymphangiectasia, the gross aspect, histological findings and electron-microscopy of which is described in detail.

[Congenital intestinal lymphangiectasia: a rare differential diagnosis in hypoproteinemia in infants].

BACKGROUND: Congenital intestinal lymphangiectasia is a rare disease in childhood, which may already cause protein-losing enteropathy in newborns. PATIENT, METHODS AND RESULTS: This is a case report of an infant with generalized edema and protein-losing enteropathy, in whom intestinal lymphangiectasia was diagnosed at the age of two months. Following repetitive intravenous albumin und gamma globulin infusions, the elimination of long-chain fats from the diet and the substitution with medium-chain triglycerides (MCT) led to an improvement of the protein-losing enteropathy. CONCLUSION: In newborns with low level of serum protein and edema protein-losing enteropathy caused by congenital lymphangiectasia might be considered as a differential diagnosis.

Intestinal lymphangiectasia: value of Tc-99m dextran lymphoscintigraphy.

Intestinal lymphangiectasia is a common cause of protein-losing enteropathy characterized by diarrhea, generalized edema, enteric protein loss, hypoproteinemia, and lymphopenia. Diagnosis is based on demonstration of enteric protein loss and characteristic small bowel mucosal histology. Various imaging modalities including barium studies, computed tomography, and lymphangiography have had limited clinical use. The authors report a case of intestinal lymphangiectasia in which Tc-99m dextran lymphoscintigraphy played a significant role in the patient management.
