ABSTRACT
In recent years, fetal or autologous stem cell transplant for the treatment of Parkinson's disease [PD] has been practiced in a few medical organizations. However, the potential complications related to the growth of allograft tissue have not yet been well described apart from case reports. Here, we present a 42-year-old Saudi male who suffered from early onset Parkinson's disease. He sought medical care in China and received autologous intrathecal stem cell transplantation. He did not demonstrate any significant improvement. A few months later, the patient went back to China and underwent fetal cell transplantation into the left hemisphere and a second stem cell transplantation intrathecally. He presented with seizures and had a left frontal brain cyst. The cyst was drained and contained clear fluid. All cultures were negative. He had an uneventful recovery
ABSTRACT
Progressive multifocal leukoencephalopathy [PML] is a rare demyelinating disease caused by reactivation of a latent JC polyoma virus. The first cases of PML were described 50 years ago in patients with lymphoma. PML typically occurs in immunocompromised individuals, particularly those infected with HIV. We present a 52-year-old male with lymphoma who was treated with R-CHOP [R: Rituximab; C: Cyclophosphamide; H: Doxorubicin; O: Vincristine; P: Prednisone]. After six cycles of therapy, the patients developed tonic-clonic seizure. MRI of the brain showed multiple brain lesions. The pathology of a brain biopsy was diagnostic for PML. We review radiographic and histopathological features of the disease. The literature on PML and its association with immunosuppressant agents is reviewed, and the impact of rituximab and other biological agents in the setting is highlighted
