Radiographic Evaluation of Patients with Schistosomiasis

Abstract

Plain films of the abdomen in advanced states of schistosomiasis reveal massive splenomegaly without evidence of splenic calcification. The liver may be enlarged in the early stages but ultimately decreases and becomes small. Ascites is evident in far advanced disease. Chest films are negative in the early stages, but in advanced disease, dilated pulmonary arteries, right ventricular enlargement, and dilatation of the azygous vein may be recognized. Granulomata are seen as multiple small rounded densities scattered throughout both lung fields. The routine barium swallow will reveal unsuspected esophageal varices. Nine patients were studied preoperatively by panhepatic angiography and 14 post-operatively following splenorenal shunt. Thrombosis of the shunt and hepatic encephalopathy were common postoperative complications.

Systemic schistosomiasis and large bowel perforation: An unexpected surgical urgency. Report of a case and literature review

“…Pulmonary schistosomiasis, although rare, can be divided into two categories: acute and chronic. Chronic and recurrent infection develops in persons living or traveling in endemic areas . The common signs at the chest CT scan in pulmonary schistosomiasis are multiple small pulmonary nodules ranging from 2 to 15 mm with ground glass opacity halo such as in our case report .…”

Aspectos Ultra-Sonográficos Da Esquistossomose Hepatoesplênica

“…A esquistossomose constitui-se em importante problema de saúde pública, sendo que as espécies de maior prevalência são o Schistosoma mansoni, o Schistosoma haematobium e o Schistosoma japonicum (1)(2)(3)(4)(5)(6)(7) . É uma doença parasitária conhecida há muitos séculos, podendo afetar vários órgãos, sendo responsável por comprometimento hepatoesplênico (1) , do aparelho digestivo alto e baixo, rins, aparelho cardiorrespiratório (cor pulmonale) e, mais raramente, do sistema nervoso central (3) .…”

Imaging of Parasitic Diseases of the Thorax

“…Radiographic and CT findings (Fig. 3.42) include right ventricular enlargement, pulmonary hypertension, dilatation of the azygous vein (due to abundant collaterals draining a hypertensive portal system), and scattered calcified nodules i.e., granulomatas throughout the lungs (Phillips et al 1975;Pagan Saez 1985). Atypical presentation simulating tuberculosis and neoplasm has been described (El Mallah and Hashem 1953;Schaberg et al 1991;Tizes et al 1967).…”

“…Diagnosis is made by identifying eggs in stool or urine samples or by rectal biopsy; sometimes lung biopsy has been proved effective. Serologic tests are not very helpful because they cannot help differentiate between a former infection and current disease (Richert and Krakaur 1959;Schwartz 2002;Schwartz et al 2000;Phillips et al 1975).…”
