To the Editor:
We read with interest the review by Mogulkoc and colleagues (August 2000)1 regarding intracardiac thrombus in 24 patients with Behçet disease previously published in 21 reports. It is also noted that the authors suggest a unique geographic distribution of this condition in the Mediterranean basin and the Middle East. However, several important articles2 3 4 from the Far East are not mentioned in the review article, although it is well-known that Japan is one of specific areas to have a high prevalence of Behçet disease. We report herein a case of Behçet disease with cardiac and pulmonary arterial thrombus from a radiologic point of view.
A 19-year-old Japanese man was admitted to our hospital in January 1996 due to hemoptysis and right heart failure. He had undergone the surgical removal of right ventricular thrombus at another hospital 9 months previously. He received a diagnosis of incomplete Behçet disease based on oral ulceration, skin lesion, uveitis, and positive human leukocyte antigen-B51. Enhanced helical CT (Fig 1 , top, middle) revealed thrombus of the right atrium, right ventricle, and right pulmonary artery. Indium-111 platelet scintigraphy (Fig 1 , bottom) showed strong uptakes in the right-sided heart and right pulmonary hiatus suggesting acute thrombus formations. Scintigraphy clarified the activity of thrombus and contributed to determining the therapeutic strategy against the serious complications of Behçet disease.

The selection of key words for a computerized search of the medical literature using the National Library of Medicines MEDLINE is important. Our case and several reported cases2 3 4 5 strongly suggest that the Far East should be included among the specific geographic distribution of patients with cardiac thrombus in Behçet disease.
