A 66-year-old male experienced the sudden onset of amnesia and generalized convulsions, and during the subsequent month developed consciousness disturbance, disorientation, memory disturbance, abnormal speech and behavior, pseudobulbar palsy, unsteadiness and urinary/fecal incontinence. The initial brain CT scan was unremarkable, and the MRI findings were also unremarkable, except for evidence of several scattered lacunar strokes in the cerebral white matter. 99mTc-HM-PAO-SPECT, however, revealed multifocal large hypoperfused lesions in the cerebrum. The erythrocyte sedimentation rate and serum CRP, LDH and gamma-globulin levels were elevated. CSF studies showed mild pleocytosis and increased protein levels. The patient's subsequent course was marked by fever, SIADH, adrenal enlargement, splenomegaly, pulmonary infiltration and pancytopenia. The neurological signs progressively worsened, until the patient lapsed into an apallic state and died 3 months after the onset of symptoms. Autopsy disclosed diffuse intravascular B lymphomatous proliferation in the brain, lungs, kidneys, adrenals, spleen and pancreas. Until now, the brain SPECT findings of IL were not very well known, but in our patient, SPECT was capable of demonstrating the pathophysiologic changes very precisely. SPECT was able to provide valuable information on the pathophysiology of IL and may therefore become another powerful tool in the diagnosis of IL.

A 73-year-old woman was presented with altered mental status and disorientation. She was diabetic and hypertensive, and she had experienced an ischemic cerebrovascular accident 3 years ago. Physical examination revealed the findings of chronic obstructive pulmonary disease, cor pulmonale and congestive heart failure. Hepatomegaly, splenomegaly and ascites were found and might be associated with postsinusoidal portal hypertension secondary to congestive heart failure. Laboratory tests showed uremia, lymphocytosis and thrombocytopenia. Neurologic findings were related with uremia and hypoxia. Multiple pathologic lymphadenopathies were seen in abdominal ultrasonography and thoracic computed tomography. Bone marrow histology indicated chronic lymphocytic leukaemia (CLL). The reason for acute renal failure was leukaemic infiltration of the kidneys due to CLL that was shown with renal biopsy. Blood urea nitrogen (BUN) and serum creatinine responded well to cyclophosphamide and methyl prednisolone treatment. In CLL, direct renal involvement is frequently seen in autopsy studies especially in advanced disease, however, renal failure due to leukaemic infiltration is extremely rare.
