Azathioprine hepatotoxicity has been described mainly in renal transplant recipients. Most reported cases are related to lesions of the venous system of the liver: peliosis hepatis, veno-occlusive disease of the liver, perisinusoidal fibrosis, and nodular regenerative hyperplasia of the liver. The most common clinical manifestation of these hepatic vascular lesions is portal hypertension. We pr...

In this case report, a female child of 10 years old presented with pain epigastrium and with sonographic features of acute cholecystitis. Later on, the focal mass in the liver was diagnosed by Magnetic Resonance Imaging (MRI) examination and proved by the biopsy as focal nodular hyperplasia (FNH), a benign focal response of the liver and a hepatic mass. Although focal nodular hyperplasia is rar...

Multiple focal liver lesions can generate diagnosis difficulties in daily practice. This paper present the case of a 53 years old patient with multiple hyperechoic liver lesions suggestive for hepatic hemangiomas, detected during the ultrasonographic exam. Contrast enhanced ultrasonography indicated focal hepatic steatosis, while computed tomography proposed possible liver metastasis. The histo...

Nodular histiocytic/mesothelial hyperplasia (NHMH) is a very rare condition. It generally thought to be associated with repeated mechanical or chemical stimulation. This study reported NHMH papillary growth pattern in the ovary following high-intensity focused ultrasound (HIFU) treatment for uterine leiomyoma and adenomyosis. A 48-year-old female, who had history of undergoing HIFU 7 times aden...

Nodular regenerative hyperplasia of the liver (NRHL) has been found in association with collagen vascular diseases, after drug therapy, with autoimmune disease, and with a variety of haematological disorders. The association of NRHL with the syndrome of Calcinosis cutis, Raynaud's phenomenon, oesophageal dysfunction, sclerodactyly and telangiectasia (CREST syndrome) has only been reported on tw...

BACKGROUND Thymic lymphoid hyperplasia is often present with myasthenia gravis as well as other autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Of the 4 cases of thymic lymphoid hyperplasia associated with Sjögren syndrome that have been reported, no case with a thymic lesion diagnosis that led to the diagnosis of Sjögren syndrome has been reported. We herein ...

Adrenal myelolipoma is a benign neoplasm composed of an admixture of hemopoietic elements and mature adipose tissue. The incidence of adrenal myelolipoma is reported as between 4% and 5% of adrenal incidentaloma. The association of an adrenal myelolipoma and adrenal nodular hyperplasia or adrenal adenoma is rare. Four cases of adrenal myelolipomas in the material of 702 incidentally discovered ...
