Ressecção de lipoma do septo interventricular

Lipomas are rare primary heart tumors and may involve the endocardium, myocardium, or pericardium. Signs and symptoms depend on the tumor location and size. The intrapericardial lipoma we report has massive dimensions and mimics a pericardial effusion. A 38-year-old male complained of dyspnea and precordial pain. On physical examination, heart sounds were diminished. The patient had received extensive medication for a clinically suspected pericardial effusion due to heart failure. A voluminous mass resembling fat within the pericardial sac was revealed by transesophageal echocardiography and a computed tomography scan. The tumor was removed successfully by a subxiphoid surgical approach. The diagnosis of a 635 gram intrapericardial lipoma was confirmed by pathological examination. After surgery, the patient recovered well and was completely asymptomatic at a follow-up at 90 days. No medications were being taken since. The diagnosis of a pericardial effusion should be secured by imaging exams to avoid unnecessary medications. Cardiac lipomas can be readily recognized by their typical features on radiologic imaging. The surgical pathology examination confirms the diagnosis and rules out malignancy criteria.

“…However patients with large symptomatic mass with severe co morbidities succumb to this major surgery. 1 , 7 Asymptomatic patients are managed conservatively and advised regular follow up with imaging, to assess for growth of the lesion. Primary neoplasm of the heart requires a thorough evaluation and CMR is the modality of choice for evaluating cardiac tumors as it helps in characterizing and differentiating the cardiac tumors.…”

“…About 75% of primary cardiac tumors are benign and lipomas are 8% among them. 1 Prevalence rate is <1 of 1000 benign cardiac tumors. Cardiac lipomatous hypertrophy is nearly always confined to the interatrial septum (IAS).…”

Primary cardiac tumors are rare. We report a case of lipomatous hypertrophy of the interventricular septum in a healthy, asymptomatic, 16 year old female, diagnosed initially by echocardiogram. Non contrast Computed tomography (CT) and Cardiac magnetic resonance imaging (CMR) were also performed to confirm the diagnosis of this rarely reported condition. Lipomatous hypertrophy of the interventricular septum is a rare form of benign cardiac tumor characterized by the proliferation of adipose tissue (fat) in the interventricular septum. This clinical entity has to be differentiated from cardiac lipoma which is a benign, encapsulated tumor. CMR helps is differentiating between the 2 conditions. As the lesion was neither causing compression of the ventricle nor obstruction to blood flow, she was managed conservatively and advised follow up.

Echocardiography is first-line examination of cardiac tumors. We report the case of a 25-year-old woman with a right atrial transmural invasive lipoma, and we review 58 published reports of primary cardiac invasive lipomas detected by echocardiography. We summarize the ultrasonographic characteristics and main sites of development, and examine the "invagination hypothesis". Echocardiography appears valuable for early detection, intraoperative monitoring, and postoperative follow-up of invasive cardiac lipomas.
