Multiple rice body formation is a complication of chronic bursitis. Although it resembles synovial chondromatosis clinically and on imaging, the literature suggests that analysis of radiographic and MR appearances should allow discrimination. We report the imaging findings in a 41-year-old man presenting with rice body formation in chronic subacromial-subdeltoid bursitis. We found that the signal intensity of the rice bodies is helpful in making the diagnosis.

We report 2 cases of Aspergillus pseudomembranous tracheobronchitis in patients with diabetes. The first patient succumbed to progressive obstructive respiratory failure despite mechanical ventilation and antifungal therapy. However, the second patient survived. Aspergillus tracheobronchitis should be considered in immuno-compromised patients presenting with cough, chest pain, fever, dyspnea and upper airway obstruction. Early bronchoscopy and histologic examination should be performed. Early, appropriate treatment may be life saving.

Aggressive angiomyxoma (AAM) is a rare soft tissue tumor typically in the pelvis and perineum in women of reproductive age, which is easily misdiagnosed. We describe a woman with vulvar AAM, initially mismanaged as a Bartholin cyst. However, a huge pelvic mass is noted on the following imaging studies. The characteristics of AAM on computed tomography and magnetic resonance imaging have been specified in the literature, but we further point out the potential value of sonography in diagnosing AAM. Besides, excisional biopsy may cause tumor bleeding in a case of AAM.

Paragonimiasis is prevalent in Far East anda kind of endemic Korean diseases. The primary site of human paragonimiasis is the lung, but the ectopic infection of lung fluke has been reported by many authors. We experienced one case of abdominal paragonimiasis in a 44 year old male with a complaint of left lower quadrant pain. Physical examination, barium enema, and other data suggested the possibility of tumor originating from the wall of descending colon. (intramural tumor). Postoperative specimen, taken from the solid tumorous lesion showed parasitic granuloma, characteristic of Paragonimus Westermani. Here, we report a case of very peculiar ectopic paragonimiasis involved descending colon wall simulating neoplastic tumor, and also review the literatures briefly .
