Sarcoidosis of the Gastrointestinal System Sarcoidosis of the On T2-weighted images when compared with the normal spleen. Rarely, an increased signal intensity of diffusely involved liver is detected They enhance less than the background liver on gadolinium-enhanced T1. The lesions are hypointense on all sequences most conspicuous on the T2-weighted fat. Focal nodules are the lesions identified in 5% of patients at imaging. However, they may alsoīe hyperechoic based on the background liver echogenicity and degree of fibrosis present in Tomography (CT) scans, relative to the background liver parenchyma. They have been reported to be hypoechoic on US and hypodense on computed Typically innumerable, diffusely distributed and range from 1 to 2 mm to several centimeters The nodules which represent the coalescence of small granulomas are Calcification is uncommon but can be seen with long. Parenchymal echogenicity, coarsening of the liver parenchyma with or without discrete Hepatic sarcoidosis and hepatocellular carcinoma. It is also suggested that there is an additional correlation between chronic Portal vein thrombosis is reported as a frequentĬomplication of hepatic sarcoidosis possibly as a result of stasis from obliteration of small Granulomas to portal hypertension and cirrhosis from granulomas in the portal triad andįibrosis due to chronic inflammation. Other findings range from asymptomatic incidental In about more than half of the patients on abdominal computed tomography (CT) scans. TheĬommonest radiologic manifestation of hepatic sarcoidosis is hepatomegaly, which is found About 50-79% of livers are involved by biopsy and 67-70% by autopsy. Sarcoidosis of the Liver follows lymph nodes and lung in the frequency of involvement.įurthermore, it is reported that a significant fraction (26%) have liver lesions without lung In some cases theĭefinitive diagnosis of sarcoidosis needs transbronchial biopsy or broncho-Īlveolar lavage especially in clinical or radiological atypical cases. Spectrum of radiological presentation of sarcoidosis. The use of high-resolutionĬomputed tomography (HRCT) provides detailed information on the wide The diagnosis and staging of the disease. Chest X-ray has been widely used in the past in Radiological appearances: half of patients is asymptomatic at the time ofĭiagnosis and the involvement of various organs can vary significantlyįrom patient to patient. Present in 25% of cases, while more rare is the involvement of central The extra pulmonary involvement, particularly skin and eyes, is In women than in men and begins most often between 20 and 40 years ofĪge. Sarcoidosis is the mostįrequent among the interstitial lung diseases, showing a higher incidence Patients, resulting in death in 5-10% of them. It resolves spontaneously in the majority of cases, butįibrosis causing permanent functional impairment develops in 20 to 25% of Pulmonary involvement in sarcoidosis is reported in up toĩ0% of patients. Sarcoidosis is an inflammatory, multisystemic, disease of unknownĮtiology, characterized pathologically by the presence of non-caseating Presenting characteristics as predictors of duration of treatment in sarcoidosis.
