Patient: Female, 54-year-old Final Diagnosis: Zoster cranial polyneuropathy Symptoms: Diplopia • facial palsy • hypoacusis • nausea • nystagmus • tinnitus • vertigo • vomiting • zoster rash Medication: — Clinical Procedure: — Specialty: Infectious Diseases • Neurology Objective: Rare disease Background: Ramsay Hunt syndrome is a rare form of herpes zoster caused by the reactivation of the varicella-zoster virus in the geniculate ganglion. The main clinical manifestations are peripheral facial palsy, vesicular rash in the ear, and ipsilateral auricular pain, and sometimes vertigo. COVID-19 is a new multisystemic infectious disease that, in addition to common respiratory manifestations, it is known to affect the immune system, primarily depressing cellular immunity. Case Report: A 54-year-old woman was admitted to our hospital with an acute vestibular syndrome and diplopia. She had been diagnosed 3 years prior with interstitial lung disease for which she was taking methylprednisolone. At admission, she tested positive for SARS-CoV-2. In the following days, she developed a sixth nerve palsy on the left side and a right peripheral facial palsy on the right side, followed by a typical zoster rash on the ipsilateral ear. One month later, she developed acute severe hearing loss on the right side. There were no COVID-19 symptoms during her stay in our hospital. The MRI showed Gd enhancement of both facial nerves. Under antiviral and corticoid treatment, the evolution was favorable, with marked improvement at 6 months. Conclusions: COVID-19 increases the risk for herpes zoster infection, probably through induced depression of the cellular immunity. Our case suggests Ramsay Hunt syndrome can be the presenting symptom and sometimes the only symptom of COVID-19. This also seems to be true for other cranial neuropathies, and we recommend testing these patients even if there are no other manifestations.

Cavernomas are rare cerebrovascular malformations that usually occur in sporadic forms with solitary lesions located most often in the hemispheric white matter, but also in the infratentorial or spinal region. Multiple lesions at different CNS levels are considered a hallmark for the familial form of the disease. The diagnostic modality of choice for cerebral cavernous malformations (CCMs) is magnetic resonance imaging (MRI). We present an intriguing case of a 65-year-old male admitted to our hospital with tetraparesis and cognitive impairment where highly sensitive MRI sequences identified many cerebral cavernous lesions at the supra-, infratentorial and cervical–thoracic spine levels, some of them with recent signs of bleeding in a patient with oral anticoagulant therapy due to atrial fibrillation. The mechanism of cognitive impairment in this patient is most probably the interruption of strategic white matter tracts, as it is known to happen in other subcortical vascular pathologies. MRI can be helpful not only in mapping the anatomical distribution of lesions, but also in weighing the risks and making decisions regarding whether or not to continue oral anticoagulant therapy.
