We have observed an increasing number of autopsies on patients with chemotherapy-related complications. One complication is toxic leukoencephalopathy, which is due to a direct toxic effect of chemotherapeutic agents on the central nervous system white matter. Autopsies of four cases of toxic leukoencephalopathy were performed following standard protocols. The brain and spinal cord were examined routinely, and histological sections were taken for evaluation. We report here three patients with hematologic malignancies and one patient with metastatic carcinoma with chemotherapy-induced leukoencephalopathy. The first was a 56-year-old male treated with multiple chemotherapeutics for multiple myeloma. He presented with confusion and focal seizures with a rapid progression to coma and decerebrate posturing. The second was a 36-year-old male who developed mental status changes, ataxia and dysarthria following treatment for lymphoma. The third was a 16-year-old male who developed a profound peripheral and central neuropathy after chemotherapy treatment for T-cell acute lymphoblastic leukemia. The fourth was a 49-year-old female patient who was treated with multiple chemotherapeutics for Stage II breast carcinoma and subsequently developed visual acuity and field defects. The neuropathologic findings in these cases, although similar, varied in severity and distribution. The white matter was affected by severe myelin pallor, edema, and a prominent macrophage infiltrate in each of the cases. The location and extent of the central nervous system pathology correlated with the type and severity of clinical symptoms. These four cases, with their varied presenting symptoms, clinical courses, and degree of pathology, emphasize the importance of considering toxic leukoencephalopathy as an etiology of acute neurologic deterioration following high-dose chemotherapy.

Cerebrovascular stroke due to Candida (C.) parapsilosis native valve endocarditis (NVE) is rarely reported. Herein, we report a 53-year man with C. parapsilosis NVE and acute ischemic stroke. Diabetes mellitus and recent dental manipulation were the preceding events. Cranial magnetic resonance imaging study revealed occlusion of left common carotid artery, and infarcts of the pons and territory of the branch of left middle cerebral artery. With a total of 4,051 mg amphotericin B therapy and aortic valve replacement, the patient survived with right hemiplegia and dysarthria. In the English literature, there have been 12 patients with C. parapsilosis NVE including our patient over the past 25 years. Intravenous drug abuse was the most common predisposing factor for this infective disorder, followed by hematological malignancy and central venous catheterization. Fever and ischemic phenomenon of lower legs were the common clinical manifestations. Cerebrovascular stroke was present only in our case. Of these 12 patients, one administered fluconazole and miconazole therapy died, while 11 with amphotericin B therapy and one patient with fluconazole monotherapy survived.

Chronic lymphocytic leukemia (CLL) is a frequent hematological malignancy, with meningeal or peripheral nerve infiltrations being the most commonly encountered neurological complications. In this report, we describe a CLL patient with Miller-Fisher syndrome (MFS) who responded to immune modulation with plasmapheresis. A 47-year-old man diagnosed as B-cell CLL admitted with neutropenic fever. He complained of diplopia and numbness of both arms. Neurological examination revealed a bilateral external ophthalmoplegia, dysphagia, dysarthria, mild shoulder girdle muscle weakness and gait ataxia, accompanied by absent tendon reflexes. Nerve conduction studies were indicative of a predominantly axonal sensori-motor peripheral neuropathy. This association of CLL with MFS had not been previously reported in the literature.
