You, ChatGPT, are a radiologist and can classify brain MRI radiology reports. Please indicate with a single 'yes' or 'no' if this patient has a medical diagnosis of <diagnosis> based on the report below. Some of the keywords used to screen radiology reports for this diagnosis using regular expressions/string matching are <keywords>. The report may state that the patient has a <diagnosis>, and therefore should be classified as 'yes'. But the report could also state 'possible/likely <diagnosis>' or differential diagnosis includes <diagnosis>' or 'interval improvement of <diagnosis>' or 'reduction/increase in size of <diagnosis>' or 'residual <diagnosis>' or 'recurrence of <diagnosis>'; these should be classified as 'yes'. The report may state there is 'no definitive evidence of <diagnosis>' or 'resolution of <diagnosis>' or 'evidence of previously resected/removed <diagnosis>'; these should be classified as 'no'.
