Question 1566
Given the position effect on the parapharyngeal space, where do you think this deep neck abscess has originated?
Question 1567
Which structure is this mixed laryngocele passing through?
Question 1568
What is the most likely source of this masticator space abscess?
Question 1605
What is the most likely cause of breathlessness in this elderly patient?
Question 1607
In a patient with low back / coccygeal pain, on standing and seated radiographs there is a 28° change in angulation of the coccyx. This measurement indicates the coccyx is:
Question 2126
A 20-year-old woman is being investigated for epilepsy and has the following MRI performed. The most likely region of seizure activity is the:
Question 2127
A 16-year-old woman has MRI findings compatible with right parietal focal cortical dysplasia. A hyperintense FLAIR tract is seen between the abnormal cortex and the ventricle. What type of FCD is this in the Blumcke classification system?
Question 2128
What is the most likely cause of this 25-year-old patient's seizures?
Question 2129
A 40-year-old woman with medically refractory epilepsy has an MRI. This shows a T2W hyperintense region at the right posterior insula, which incompletely suppresses on FLAIR at the periphery. There is no enhancement following intravenous contrast administration. What is the most likely lesion causing this patient's seizures?
Question 2130
This 60-year-old man suffered a penetrating neck injury. A contrast-enhanced CT is performed, with a skin and soft tissue defect through the left sternocleidomastoid, just superior to the level of the carotid bulb. The trauma surgeon wants to know the zone of injury. You can tell them this is a...
Question 2131
This 50-year-old man was involved in a road traffic collision, with blunt force trauma to the neck. There is evidence of supraglottic trauma on endoscopy. Which laryngeal structure is damaged on this CT?
Question 2133
This 50-year-old man experienced neck pain, with left pupillary abnormality and swallowing difficulty. An MRI is performed a few days later, with the T1W fat saturated sequence confirming the left internal carotid artery dissection. What is the hyperintensity on the T1FS sequence?
Question 2134
This 18-year-old suffered a head and cervical spine injury after crashing his mountain bike off a jump. He is quadriplegic.
CT and MRI were performed.
What is the WORST prognostic sign in this case?
Question 2453
A lesion is observed in the thoracic spine. There is abnormal signal in the spinal cord (which narrows at the level of the lesion) with expansion through the neural foramen. This is best described as:
Question 2454
What is the most common type of adult intramedullary (spinal) tumour?
Question 2455
Which of these extramedullary lesions are commonly seen with vertebral segmentation abnormalities?
Question 2456
What structure is demonstrated by the yellow lines?
Question 2481
This adult patient with reduced upper and lower limb sensation and balance has this finding on their MRI cervical spine. What next investigation would be most useful?
Question 2482
This young adult sustained a high energy head injury. From this sagittal STIR MRI cervical spine sequence, can you tell the clinical team why the patient is quadriplegic?
Question 2755
Which of these structures do not typically drain into level IA nodes?
