RESUMO
We report a case of enteropathy-associated T-cell lymphoma (EATL) of the jejunum in a 56-year-old man. The patient suffered for several years from nonspecific abdominal complaints, with no clinical evidence of malabsorption. The patient underwent extensive imaging procedures including barium meal and computed tomography. Computed tomography of the abdomen showed small mesenteric lymph nodes and an area of intestinal wall thickening. Barium meal demonstrated a short jejunal stricture. Histology revealed lymphoma of the jejunum, with microscopic changes distant from the lesion consistent with celiac disease. The spectrum of EATL ranges from patients with frank celiac disease, to patients with only immunohistochemical evidence of celiac disease, who develop small bowel lymphoma.

Brucellosis is an infectious disease transmitted from various animal hosts to man. In children the most common route of infection is unpasteurized milk or milk products. Brucellosis affects the urinary tract uncommonly, most frequently causing orchioepididymitis. We report the case of a 4-year-old boy with brucellosis who developed acute focal bacterial nephritis (AFBN), documented by sonography, gallium scan, and computed tomography. After appropriate treatment his symptoms and his sonographic abnormality resolved completely. To the best of our knowledge, this is the first report of the association of AFBN and brucellosis.

Echinococcal disease is endemic in many areas of Asia, Europe, South America, the Near East, Australia, and New Zealand. Hepatic and pulmonary cysts are the most common presentation. Isolated renal hydatid cyst is an uncommon presentation of echinococcal disease, since renal involvement occurs in only 2-3% of cases. We present the case of a young man with renal colic, in whom the diagnosis of renal hydatid disease was established cytologically. Urine cytology, performed because of persistent hematuria, revealed scolices of Echinococcus granulosus and prompted further imaging investigation, and, ultimately, surgical treatment.

Oxyphil carcinoma of the parathyroid is an extremely rare tumour, only two previous patients having been reported. We report a 55-year-old woman with this condition, who presented with a picture of hyperparathyroidism, including hypercalcaemia, hypercalciuria, hypophosphataemia, increased alkaline phosphatase, and bony lesions. Biopsy of a bone lesion was consistent with brown tumour. Fine needle aspiration cytology and subsequent operative histology of the parathyroid lesion showed an oxyphil cell tumour with malignant characteristics. Following excision, the patient made a good recovery, complicated only by postoperative hypocalcaemia.

We present a case of inflammatory pseudotumor of the liver (IPL), a rare benign hepatic lesion. A 66-year-old woman with fever, and right abdominal pain and mass underwent abdominal sonography and computed tomography. Both showed multiple hepatic masses. Ultrasound guided needle liver biopsy showed a dense chronic inflammatory lesion with innumerable foamy histiocytes and spindle fibroblasts consistent with IPL. She improved with conservative treatment. Clinical, pathologic, and imaging findings at IPL are reviewed.

A case of acute focal bacterial nephritis in a child is presented. Imaging findings for various modalities are discussed (nuclear medicine, ultrasound, computed tomography, and conventional radiology) with a suggestion for optimal imaging strategy in these cases.
