Unorthodox diagnostic procedure in a rare case of intrapericardial malignant schwannoma.
To establish preoperatively the cytology of a large right atrial tumour, an echoguided transcutaneous thin needle aspiration using a transhepatic approach was performed. Cytology suggested myxoma, which had been mimicked by regressive changes within the tumour, while the histologic examination of the removed specimen revealed a malignant pericardial Schwannoma. In spite of this discrepancy we think that solid tumours located at the free atrial wall are accessible to ultrasound guided puncture without great risk.
