Abnormally high uptake of technetium-99m hexakis-2-methoxyisobutylisonitrile (99mTc-SESTAMIBI) in the right ventricle and in the septum was observed in a 47-year-old woman initially presenting with dysarthria and left hemiparesis. Endomyocardial biopsy demonstrated a high-grade malignant non-Hodgkin's lymphoma. Complete remission was achieved by combined cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) chemotherapy and radiotherapy of the heart and mediastinum. The post-remission single photon emission tomography (SPET) 99mTc-SESTAMIBI study showed a homogeneous distribution pattern, in agreement with echocardiography computed tomography and magnetic resonance imaging. Increased uptake of 99mTc-SESTAMIBI, a myocardial perfusion agent, has been observed in some benign and malignant tumours. It may prove to be useful in the diagnosis and follow-up of malignancies.

A 51-year-old man with a diagnosis of myelodysplasia and non-Hodgkin's lymphoma underwent an unmatched allogenic bone marrow transplantation and was treated posttransplant with chronic immunosuppressive medication. Eight months following transplantation, he presented with progressive dysarthria, cognitive and visual decline. Evaluation included brain magnetic resonance (MR) imaging demonstrating multifocal areas of increased T2 and FLAIR (fluid attenuated inversion recovery) signals involving the left frontal, parietal, and occipital lobes. The MR lesions demonstrated diffuse increased signal on DWI (diffusion-weighted images) and normal to low signal on ADC (apparent diffusion coefficients). Contrast-enhanced T1 images were unremarkable. Lumbar puncture revealed a mild elevation in cerebrospinal fluid (CSF) protein. CSF PCR assay for viral DNA fragments were negative on two occasions. Serum serology for HIV was negative as well. A brain biopsy was subsequently performed. The clinical and neuroimaging differential diagnoses as well as neuropathologic correlation are presented.

Primary CNS lymphoma (PCNSL) and its variant primary intraocular lymphoma (PIOL) are rare forms of extranodal non-Hodgkin's lymphoma confined to the CNS including the retina and the optical nerve; histologically, most cases are diffuse large B cell lymphomas. PCNSL in immunocompetent patients display typical radiological features on MRI, i.e. intensely and homogeneously enhancing lesions with moderate edema. Here, we report a 52-year-old male with a history of a PIOL and two consecutive intracerebral relapses who presented with dysarthria, dysphagia, and gait ataxia. Gadolinium-enhanced T1 scans were unremarkable but multiple lesions with restricted water diffusivity were seen on diffusion-weighted imaging. Relapse of his PCNSL was secured histologically only on autopsy. The possible etiology of the diffusion-restricted lesions is discussed.
