A Rare Case of Undifferentiated Pleomorphic Cardiac Sarcoma.

We present a case of a patient with a four-month history of gradual-onset dyspnea and generalized body weakness. During the clinical evaluation, a mass was found in the left atrium. Coronary angiography was performed and showed normal coronary arteries. We proceeded with a complete surgical excision of the tumoral mass, and histopathology confirmed it as undifferentiated cardiac sarcoma. Six months after the surgical intervention and adjuvant chemotherapy, the patient is in complete remission, with no evidence of a recurrence of the malignant pathology. Cardiac sarcoma is a rare clinical finding and a diagnostic and therapeutic challenge due to its numerous non-specific clinical presentations.

Hepatic Hydatid Cyst Presenting as Right-Sided Heart Failure: A Case Report.

Cystic echinococcosis is a parasitic disease caused by Echinococcus granulosus. The transmission of the parasite to dogs occurs when organs of animals that harbor hydatid cysts are consumed. We present the case of a patient presented in the cardiology outpatient clinic with the signs and symptoms of predominant right-sided heart failure. Upon evaluation, a large hepatic septated cyst was revealed, which was compressing the right chambers of the heart, altering diastolic filling, and causing right-sided heart failure. CT scan confirmed the presence of a hydatid cyst measuring 115 mm × 90 mm. The patient underwent surgical excision of the cyst with immediate relief of the symptoms. Two weeks later, the patient presented again with the same symptoms and was diagnosed with a recurrence of the hydatid cyst. He underwent surgical resection and removal of the cyst again. The patient remained asymptomatic and free of recurrence on further follow-up evaluations. Cardiac echinococcosis typically features intra-myocardial cysts, while our case presented an extracardiac location. Extrinsic compression of the heart's right chambers from a hydatid cyst has been rarely reported. The surgical excision of the cyst brings immediate and full resolution of the symptoms. The recurrence of hydatid cysts is also an important clinical feature that should not be underestimated.
