Neurosurgery Modules - Formative Review

[blank_start]Lateral Corticospinal Tract[blank_end]: voluntary motor control of limbs and digits. [blank_start]Anterior Corticospinal Tract[blank_end]: voluntary motor control of the trunk and maintains posture.

Which lesions correspond to the presentations below?

Which tract originates in the red nucleus of the midbrain?

A 30 year old man presented with a stab wound in his back. He has right sided weakness starting at T5 and left sided loss of pinprick sensation and temperature starting at T7.

Which type of cerebral haemorrhage presents as the following: Severe “thunderclap” headache, meningeal irritation and loss of consciousness

Extradural haemorrhages usually occur due to damage to the [blank_start]middle meningeal[blank_end] artery

Which of the following cerebral haemorrhage usually has a venous origin (cerebral bridging veins)?

A CT Angiogram would give a definitive diagnosis for which of the following conditions?

Match the blood vessel to where blood would accumulate if it were to be damaged: Bridging Cerebral Vein - [blank_start]Between Dura and Arachnoid[blank_end] Posterior Communicating Artery Aneurysm - [blank_start]Between Arachnoid and Pia[blank_end] Middle Meningeal Artery - [blank_start]Between Bone and Dura[blank_end]

Match the clinical description to the definitive diagnostic tool: A 70 year old patient presents with progressive headaches and nausea with gradual loss of sensation in her right arm. Imaging reveals a mass in the temporal lobe. [blank_start]Biopsy[blank_end] A 25 year old boxer lost consciousness in his final fight due to a punch in the head but was in a good state straight after. However, 4 hours later his GCS was 6/15. [blank_start]CT Scan[blank_end] A 25-year-old man developed a sudden onset 'worst ever' headache and collapsed. [blank_start]CT Angiography[blank_end]

A patient presents unconscious with unilateral pupil mydriasis that does not constrict to light following a car accident. On CT, an intracranial hemorrhage with cerebral herniation. What is the most likely cause from the options below?

Match the stroke type to the symptoms it causes: [blank_start]Anterior Circulation Stroke[blank_end] - Higher cerebral dysfunction (e.g. dysphasia), Homonymous visual field defect and contralateral motor and/or sensory deficit of at least two areas (out of face, arm and leg). [blank_start]Posterior Circulation Stroke[blank_end] - Cerebellar dysfunction, Isolated homonymous visual field defect and Cranial nerve dysfunction [blank_start]Lacunar Stroke[blank_end] - A pure motor or pure sensory stroke

Diagnose this patient: A 70-year-old male with left homonymous hemianopia. He has no other symptoms
