A case of intravascular large B-cell lymphoma complicated by hypercalcaemia

Intravascular large B-cell lymphoma, a rare, clinically aggressive type of B-cell non-Hodgkin's lymphoma, is prone to central nervous system disturbances, including altered consciousness.Hypercalcaemia, which causes impaired consciousness, is extremely rare in intravascular large B-cell lymphoma, occurring more often in other non-Hodgkin's lymphomas.Parathyroid hormone-related protein is elevated in most cases of intravascular large B-cell lymphoma with hypercalcaemia, which may present as humoral hypercalcaemia of malignancy.
