Based only on what you know so far, what seems like a plausible explanation for her recurrent headaches?

Sprint 11: Three Months of Recurrent Headaches

Review the CT finding more closely, including its location and severity

Clarify whether she has symptoms that would clinically connect the sinus abnormality to her headaches

Characterize the headache episodes more precisely, including associated symptoms and triggers

Clarify whether the headache pattern has changed over the three months or developed concerning features

Dismiss the CT finding because it no longer appears to explain the headaches

Reduce its explanatory weight for the headaches because the clinical pattern supports another explanation and lacks corresponding sinonasal features

Maintain substantial weight because the CT abnormality remains objective evidence

Leave its explanatory weight unchanged until additional information determines whether the imaging abnormality is clinically significant
