Sometimes, the clinical presentation of a @entity1313 mimics that of @entity64 or vice versa, as exemplified in the following three @entity1 . In a 73-year-old @entity1 the initial clinical picture was compatible with a @entity5300 , as the weakness in his right hand appeared to have a traumatic, and not a central nervous system related, cause. When he experienced a focal @entity410 , the CT scan of the brain revealed a lesion in the motor cortex. This was presumed to be an @entity1188 due to the lack of mass effect and the absence of contrast enhancement. Shortly afterwards the @entity1 deteriorated and a follow-up scan revealed a large contrast-enhancing lesion. During surgery this proved to be a @entity463 multiforme. A 76-year-old @entity1 was suffering from a progressive @entity51 . An MRI scan of the brain revealed a contrast-enhancing lesion and a chest X-ray revealed an asymptomatic @entity5 ; the diagnosis 'brain @entity3 ' was made. The surgeon removed the @entity5 , which proved to be a @entity189 . Later, when the @entity1 was referred to the neurosurgeon for extirpation of the presumed brain @entity3 , the MRI scan revealed that the lesion had decreased in size and no longer exhibited contrast enhancement. The @entity3 proved to be an @entity1188 . A 53-year-old @entity1 presented with @entity909 due to a @entity548 in the occipital lobe. An angiogram did not reveal a @entity1462 and during surgery no abnormal tissue was seen. The @entity1 almost made a complete recovery. However, several months later he developed an @entity428 due to a large occipital high-grade @entity11 , which had caused the original @entity548 .
