1. What is the underlying diagnosis? What complication has occurred?

2. What is the underlying cause and how can it be confirmed?

- Refer surgeons
- Consider CT scan
Infectious mononucleosis (IM) is usually a self-limiting infection, most often caused by Epstein-Barr virus (EBV), which is a human herpes virus. However, approximately 10% of those with IM are not acutely infected with EBV and many of these have symptoms attributable to cytomegalovirus (CMV) infection.

Question 9:
36 year old female presents complaining of spilling liquids when she tries to drink.
- Give 4 causes of this presentation

1. Give 4 causes of this presentation
- Bell’s palsy
- Ramsey hunt syndrome
- Otitis media
- CVA
- Munps
- Trauma/inflammation parotid gland
2. Describe the anatomy and how this impacts on presentation of this condition.
- Facial nerve originates in facial nucleus in pons, lesions above this are UMN lesions and appears clinically with sparing of forehead on affected side due to bilateral innervation.
- Then crosses cerebellopontine angle to enter internal auditory canal and geniculate ganglion. Lesions at this point are associated with weakness of facial muscles, abnormal lacrimation, reduced taste sensation to ant 2/3 tongue, hyperaccusis.
- Branch arises from geniculate ganglion, greater superficial petrosal nerve to supply lacrimal glands.
- Rest of nerve passes through petrosal temporal bone giving off branches ant 2/3 tongue and submandibular and sub-lingual salivary glands –chorda typmani. Further branch, nerve to stapedius also arises here.
- The nerve exists at the stylomastoid foramen and enters parotid gland before giving nerves off to muscles of facial expression. Lesions of nerve in parotid gland are associated with facial muscle weakness but normal taste/ hearing.

45 year old man presents complaining of ear ache and a “lopsided face”.
- What is the diagnosis?
- How would you manage this patient?
1. What is the diagnosis?
- Ramsey hunt syndrome – infection of geniculate ganglion by varicella zoster virus
The Ramsay Hunt syndrome occurs when the varicella zoster virus (chickenpox) becomes reactivated in the geniculate ganglion of the VIIth cranial nerve (facial nerve).

- Analgesia
- Acyclovir 800mg 5X/day for 7/7
