1/139. Recurrent myxoma of the left ventricle. Case report and review of the literature.

    A 29-year-old female was found to have a left ventricular mass while in the 14th week of gestation. Seven years earlier she had undergone removal of a left ventricular myxoma. At re-operation, after elective interruption of pregnancy, a recurrent left ventricular myxoma was successfully excised. According to a review of the literature recurrence of an isolated, localized left ventricular myxoma has not been previously reported.

2/139. Late diastolic tumor "plop" in an asymptomatic case of right atrial myxoma.

    Myxomas of the right atrium are rare tumors of the heart. They have been almost always described as symptomatic tumors. auscultation and phonocardiography have been revealed tumor "plop" (P) as an early diastolic phenomenon, but the late "plop" has not be described. The aim of the case report is to present late diastolic tumor "plop" in an asymptomatic case of right atrial myxoma. A thirty year old man without any subjective symptoms was admitted to the clinic because of a murmur found during a routine examination when applying for a new job. Two dimensional echocardiography showed slightly enlarged right atrium with a myxoma in it. M-mode echocardiogram taken from parasternal short axis plane revealed a wide cluster of echoes in the right atrium moving into the right ventricle inflow tract in diastole. Simultaneous phonocardiogram showed splitting of the first sound (0.06 sec.). The tumor "plop" occurred in late diastole, 0.22 seconds after the second sound (S2) and coincided with maximum tumor protrusion into the right ventricle. After successful operation of the tumor without catheterisation, echophonocardiographic finding has become quite normal.

3/139. Serial MRI of cerebral infarcts before and after removal of an atrial myxoma.

    We describe a cerebral infarct caused by atrial myxoma. A 30-year-old woman with an atrial myxoma presented with a right hemisensory deficit. MRI carried out before and after removal of the myxoma, showed multiple small bilateral white-matter infarcts which increased in number up to the surgery. A lesion in the left thalamus, which enlarged and showed contrast enhancement 4 months before surgery, resembled an old cerebral infarct by the time the myxoma was removed. The number of lesions stopped increasing after surgery. We suggest that atrial myxomas should be removed even in asymptomatic patients, to prevent cerebral infarcts due to embolism of tumour or thrombus.

4/139. Biatrial myxoma resembling an interatrial clot in transit on echocardiogram.

    A 47-year-old man had an embolic stroke. Transesophageal echocardiography showed biatrial, elongated, mobile masses that appeared interconnected via a patent foramen ovale. echocardiography did not distinguish between an interatrial clot in transit and an atypical biatrial myxoma. Surgical resection and subsequent histopathologic examination identified the mass as a biatrial myxoma. This case identifies a limitation of echocardiography in the diagnosis of cardiac myxoma.

5/139. Cutaneous manifestation of left atrial myxoma.

    A 53-year-old woman had a left hemiplegia with suspicion of cerebral metastases. Thoracic and abdominal computed tomography revealed renal and splenic infarction features and she presented violaceous papulosis on her fingers corresponding to thrombosis of dermal vessels. echocardiography showed a left atrial tumor evoking myxoma. The clinical features of left atrial myxomas are intracardiac obstruction, extracardiac embolism and general symptoms. Cutaneous manifestations are frequently reported and can correspond to cutaneous manifestations of emboli, symptoms related to auto-immune disorders and specific cutaneous findings that suggest atrial myxoma as part of more complex syndromes.

6/139. Left ventricular myxoma: report of a case.

    Although recent advances in echocardiography have made it easier to detect cardiac tumors, left ventricular myxomas are still rare and often not found until the patient presents with a history of syncopal episodes or systemic embolization. Left ventricular myxomas are usually benign and curable; however, unreliable excision of the myxoma due to poor visualization of the left ventricular cavity can result in recurrence. To prevent recurrence, it is necessary to select the most appropriate surgical approach to excise the myxoma completely. We report herein the case of a patient in whom surgical excision of a left ventricular myxoma arising from the posterior wall of the left ventricle was successfully performed.

7/139. Fatal cerebral embolism in a young patient with an occult left atrial myxoma.

    We report a young patient with a fatal cerebral embolism from an occult atrial myxoma. The patient died before echocardiography was performed and at autopsy the definite diagnosis was made. Our patient suffered from migraine of increasing frequency. The physical exercise of sexual intercourse was the precipitating factor of this fatal embolism. The importance of early echocardiography is stressed, especially in view of the recent tendency of early and aggressive stroke treatment.

8/139. Multiple intracranial aneurysms as delayed complications of an atrial myxoma: case report.

    OBJECTIVE AND IMPORTANCE: Atrial myxomas are rare cardiac tumors that may cause neurological complications; however, delayed neurological events after total tumor resection are rare. In this report, we present a patient who developed transient cerebral ischemic attacks and was found to have multiple intracranial aneurysms 5 years after successful resection of her atrial myxoma. At the time of myxoma resection, there were no neurological symptoms; at the time of presentation with transient ischemic attacks, there was no evidence of atrial recurrence. CLINICAL PRESENTATION: A 32-year-old woman presented with five episodes of right arm and face paresthesia, each lasting 15 to 20 minutes, 5 years after successful resection of her atrial myxoma. Clopidogrel bisulfate therapy was initiated, with resolution of her symptoms. Angiography revealed multiple, peripherally located, fusiform cerebral aneurysms. INTERVENTION: A left frontal craniotomy for resection and biopsy of one of the aneurysms was performed, to establish the diagnosis. Pathological analysis of the biopsied aneurysm provided evidence of direct atrial myxoma invasion and occlusion of the cerebral blood vessel. CONCLUSION: Neurological symptoms may accompany or lead to the diagnosis of atrial myxoma. Rarely, as in this case, myxomatous aneurysms may develop years after definitive treatment of the primary tumor. patients who have undergone successful resection of a left atrial myxoma may be at risk for delayed cerebral ischemia associated with aneurysm development, and this phenomenon must be considered for patients with neurological symptoms who present even years after myxoma removal. The natural history, pathophysiological features, and treatment dilemma of these aneurysms are discussed.

9/139. MR diagnosis of myxomatous aneurysms: report of two cases.

    We report two cases in which MR imaging was used to diagnose multiple cerebral aneurysms caused by cardiac myxoma. In one case, the diagnosis was confirmed with cerebral angiography. Myxomatous aneurysms characteristically appeared on T1-weighted images as contrast-enhancing focal fusiform dilatations of distal segments of the cerebral arteries. On T2-weighted images, these myxomatous aneurysms appeared as low signal intensity flow voids, sometimes associated with cerebral infarctions.

10/139. Intramuscular myxoma causing lumbar radiculopathy. Case report and review of the literature.

    The authors present the rare case of a myxoma, a benign soft-tissue tumor of mesenchymal origin noted for occurring in the left atrium of the heart, which was found in the lumbar paraspinal muscles of an 80-year-old woman. This patient experienced low-back pain for over 20 years and had noted its increasing severity with the development of an L-5 radiculopathy over a 3-month period. magnetic resonance imaging of the lumbar spine revealed a large paraspinal mass that invaded the L-5 vertebral body and the left foramen of L5-S1. A computerized tomography-guided biopsy sampling procedure was performed, and examination of the specimen revealed an intramuscular myxoma. The patient underwent resection of the tumor and nerve root decompression. The diagnosis of intramuscular myxoma was confirmed, and the patient experienced complete resolution of her presenting symptoms. This patient represents the third reported case (the first in the English-language literature) of an intramuscular (paraspinal) myxoma presenting with lumbar nerve root compression.
