Lipomatous hypertrophy of the interventricular septum.

BACKGROUND AND AIMS: Lipomatous hypertrophy of the interatrial septum is an uncommon type of cardiac adipose tumor. It is extremely rare for these lesions to be located in the interventricular septum. METHODS: We report this case of incidentally diagnosed lipomatous hypertrophy of the interventricular septum with right ventricular outflow obstruction which caused minimal symptoms and Wolff-Parkinson-White pattern on EKG. CONCLUSION: We also discuss the diagnosis and management of this condition.
