Constrictive pericarditis in B cell chronic lymphatic leukaemia.

We report a case of B-cell chronic lymphatic leukaemia (B-CLL) complicated by constrictive pericarditis. The pericardial involvement was confirmed histologically to be leukaemic in nature. We draw attention to this complication which is amenable to surgical correction. To our knowledge this has been described only once before as an autopsy finding and has not been encountered ante-mortem.
