Case Report: Giant left atrial cystic tumor: myxoma or intracardiac blood cyst?

ABSTRACT:

Background

Primary cardiac tumors are uncommon, with the majority being benign myxomas. Cystic myxoma, a particularly rare type of benign cardiac tumor, demands cautious differential diagnosis from other cardiac tumors.

Case summary

A 43-year-old male patient presenting with intermittent dyspnea was referred to our department for surgical evaluation. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) unveiled an intra-left atrial cyst, which was subsequently found to be blood-filled during a video-assisted microinvasive heart surgery. Pathological examination depicted a cyst wall filled with small stellate and fat spindle cells, along with a mucoid matrix, indicating a diagnosis of cystic myxoma.

Conclusions

We herein presented a rare case of an adult patient with cystic myxoma, initially misdiagnosed as an intracardiac blood cyst (CBC) prior to surgery, and ultimately verified via pathological findings.

An exceptionally giant left atrial myxoma: a case report and literature review.

Project description:BackgroundCardiac myxomas are considered the most common benign heart tumours. The clinical manifestations mainly depend on the size of the tumour. They usually vary from asymptomatic, mild non-specific symptoms, to severe obstructive cardiac and systemic findings. We describe herein a significantly large left atrial myxoma in a patient misdiagnosed with respiratory asthma.Case summaryA 54-year-old lady, was diagnosed previously with asthma, presented with a history of dyspnoea on exertion, palpitations, and mild peripheral oedema. Chest X-ray suggested pulmonary congestion. Due to high suspicion of cardiac issues, transthoracic echocardiography was done revealing giant left atrial mass. Consequently, the mass was approached and excised surgically through the inverted T biatrial incision. Grossly, the mass measured 10 × 8 × 6 cm, and it had a smooth surface and was filled with gelatinous material. The histopathology confirmed benign myxoma without malignant features.DiscussionOur article mainly focuses on the diagnostic challenges of a patient with atrial myxoma. The major discrepancy between the tumour size and the severity of the patient's symptoms should draw physicians' attention to consider atrial myxoma over a long list of differentials, in order to take immediate action to reduce the mortality and improve the overall prognosis.

Acute heart failure due to a giant left atrial myxoma: a case report.

Project description:BackgroundCardiac myxomas are the most common primary benign tumour of the heart. Most of them occur between the 4th and 6th decade of life, are most frequent in the woman, and most frequently localized in the left atrium.Case summaryWe present a case of a 41-year-old female who presented with a history of left-sided heart failure. A left atrial mass of 87 × 88 × 65 mm was documented by cardiac magnetic resonance. She was taken to surgical resection of the mass. Histopathologic findings were diagnostic of cardiac myxoma. Generally, myxomas that are bigger than 6 cm are associated with the worst prognosis.DiscussionPrimary cardiac tumours are mostly benign, being in 50% of the cases a cardiac myxoma. The rest of them correspond to papillary fibroelastoma (26%), fibromas (6%), lipomas (4%), and others including calcified tumours, haemangiomas, teratomas, cysts, and rhabdomyomas. Our clinical case illustrates an unusual and rare presentation of cardiac myxoma with a double mitral lesion.

A "Ping-Pong" left atrial thrombus mimicking left atrial myxoma: A case report.

Project description:IntroductionValvular heart disease is highly prevalent, especially in developing countries. Mitral Stenosis (MS) is a condition where there is narrowing of mitral heart valve. Left atrial (LA) thrombus is often seen in severe MS patients.Case presentationA 47-year-old woman complained of palpitation and shortness of breath. The heart sounded irregularly irregular, with grade III/IV diastolic murmurs at the apex. Her electrocardiogram showed atrial fibrillation (AF) with rapid ventricular response Transthoracal echocardiography (TTE) showed severe MS, mild tricuspid regurgitation, and LA thrombus. Mitral valve replacement surgery, tricuspid valve repair, and evacuation of the LA thrombus were immediately done. We evacuated a spherical mass with a size of 4 × 3x2.2 cm, layered and easily separated. Microscopic examination showed extensive fibrin and bleeding with mononuclear inflammatory cells and macrophages, corresponding to a thrombus conclusion.Clinical discussionAtrial thrombus is common in MS patients. The incidence will increase by about two times in patients with AF. TTE is a reliable tool in diagnosing large mobile atrial thrombus and differentiated it from other cardiac masses. However, histopathological examination is still the gold standard to distinguish between LA thrombus and myxoma. Immediate thrombus evacuation and valve replacement, if needed, will give good results and reduce systemic thromboembolism.ConclusionLA thrombus is often seen in a patient with severe MS. Optimal preoperative preparation involves assessing preoperative risk stratification will give good results.

A rare giant atrial septal cardiac blood cyst in an adult: a case report.

Project description:BackgroundCardiac blood cysts are exceedingly rare cardiac tumours usually found on cardiac valves in infants. We report and discuss a rare unique case wherein a giant atrial septal cardiac blood cyst was found in an adult.Case summaryA 59-year-old Chinese lady with history of hypertension, hyperlipidemia and transient ischaemic attack presented with atypical chest pain. Her ECG suggested right ventricular strain. Echocardiography revealed a large right atrial intracardiac mass attached to the interatrial septum which prolapsed into the right ventricle during each cardiac cycle with associated dilatation of the right atrium and right ventricle. Computed tomography scans showed no evidence of malignancy or metastasis. Considering our patient's profile and the characteristics of the mass, it was opined to likely be a cardiac myxoma. After consultation with our cardiothoracic surgeons, she underwent surgical resection of the intracardiac mass. Histology revealed that the intracardiac mass was a cardiac blood cyst.DiscussionFirst described by Elsasser in 1844, cardiac blood cysts are extremely rare benign cardiac tumours very rarely seen in adults. Though benign, they have been associated with outflow tract obstruction, valvular regurgitation and embolization. Symptomatic patients do well with surgical resection, while long-term outcomes in asymptomatic patients followed up with serial echocardiograms are mixed. Due to its rarity, existing literature is limited to case reports and small case series, with a lack of guidelines on management till recently. Our case report serves to highlight this unique presentation of an exceedingly rare intracardiac tumour.

Left Atrial Myxoma Masquerading as Pulmonary Embolism on Electrocardiogram: A Case Report.

Project description:Primary cardiac tumors are an incredibly rare finding. Cardiac myxomas are the most primary cardiac tumors that often occur within the left atrium. When left untreated, they pose a high risk of causing hemodynamic collapse by obstruction or can embolize and result in thromboembolic stroke. The presentation of cardiac myxoma varies greatly and can be associated with significant morbidity and mortality when undiagnosed. A careful physical examination and high degree of suspicion is crucial in early diagnosis and intervention. Our team presents a 46-year-old female patient with no significant past medical history that presented to the emergency department with a neurological deficit that was concerning for a transient ischemic attack. Initial laboratory workup and electrocardiogram was suggestive for pulmonary embolism; however, upon evaluation with imaging, the patient was found to have a 1.6 × 3.4 cm mass fixed to the mitral leaflet that was then confirmed on transthoracic echocardiography. Our patient was found to have non-obstructive coronary artery disease on cardiac catheterization and ultimately underwent successful mass resection by cardiothoracic surgery.

Giant Left Atrial Myxoma Masquerading as Cough-Syncope Syndrome.

Project description:Left atrial myxomas are the most common type of benign primary cardiac tumor. Patients can present with generalized symptoms, such as fatigue, symptoms from obstruction of the myxoma, or even embolization of the myxoma causing distal thrombosis. We describe a case with several-month duration of syncopal episodes that occurred after coughing and with exertion. Computed tomography of the chest showed a 6.1 cm by 4.5 cm mass in the left atrium, later evaluated with an echocardiogram. Cardiothoracic surgery removed the mass, and it was determined to be an atrial myxoma. It is important for an internist to be able to diagnose an atrial myxoma because of the risks associated with embolization and even sudden death as myxoma can block blood supply from atrium to ventricle.
