Who do we need to scan? Behind the constant considerations of irradiation risk and resource usage, there is nuance to be found. Parkinson's disease - being a clinical diagnosis - doesn't suggest a need for imaging, yet one case in this issue argues that should not be an absolute rule. Another paper brings in the context of a specific patient: does one man really need 50 CT scans in his life? There's also an unboxing of uveitis, diagnosis of Alexander disease in adults, and an exploration of connections between the microbiome and neurology. This being the fifth(!) Christmas podcast for editors Phil Smith and Geraint Fuller, they finish with the annual crossword and book club update, featuring hot cross buns and hummingbirds.

Two new cases from the latest issue of the journal present the podcast team with some rare explanations, and a chance to test yourself on food trivia.  

In the first case (1:18), from Malaysia, a 49-yo left-handed woman develops 10 days of recurrent left-sided focal facial seizures. These seizures progressed to epilepsia partialis continua, which is controlled with some difficulty by employing a broad range of six different anti-seizure medications. Further symptoms arose during monitoring, including emotional lability as well as dystonia, left arm dysfunction, dysphasia and dysarthria. EEG imaging showed focal slowing in the right hemisphere.

The second case (22:20) features a Northamptonshire chef in her 60s, who presents to the emergency department with a week-long history of nausea, vomiting, and abdominal pain. This progressed to dysphagia and dypsnoea, as well as a downshift in the pitch of her voice. Her conditioned worsened, with respiratory arrest requiring CPR to re-establish circulation. Neurological examination was initially done while sedated, showed fixed and dilated pupils.

Overloaded with Greek terms today? Here are some definitions from BMJ Best Practice and NHS UK:

The case reports discussion is hosted by Prof. Martin Turner¹, who is joined by Dr. Ruth Wood² and Dr. Babak Soleimani³ for a group examination of the features of each presentation, followed by a step-by-step walkthrough of how the diagnosis was made. These case reports and many others can be found in the October 2025 issue of the journal.
