Non-small-cell lung cancer harboring an activated epidermal growth factor receptor mutation exhibits a good response to epidermal growth factor receptor-tyrosine kinase inhibitors; however, clinicians often experience treatment failure following the development of resistance to epidermal growth factor receptor-tyrosine kinase inhibitor. ⋯ This case demonstrates the detection of T790M was associated with the clinical responsiveness to epidermal growth factor receptor-tyrosine kinase inhibitor.

Persistent migraine aura without headache is an extremely rare condition. The International Headache Society defines various subtypes of migraines, including "persistent migraine aura without infarction" and "typical aura without headache." ⋯ Persistent visual aura without headache overlapped the criteria for the two migraine subtypes mentioned above and thus did not fit an exact diagnosis. Therefore, we assert that new criteria are needed to encompass uncertain visual symptoms of migraine aura.
