The patient's headache progressively worsened and the abducens nerve palsy continued; radiographs of the pleural effusion in the left hemithorax and the MRI of the skull were also unchanged. The sixth cranial nerve sends signals to your lateral rectus muscle. The patient was treated with analgesics and hormonal therapy with improvement in symptoms and eventual resolution of PA without the need for surgical intervention. Al- though the degree of left abducens nerve palsy was im- proved, it is still present (Fig. SARS-COV-19 virus is a neurotropic virus and can indirectly affect motility secondary to venous/arterial thrombosis. On neurological examination, the patient was found to have left abducens nerve palsy. Abducens nerve palsy leads to lateral rectus palsy, resulting in an inability to abduct the eye and horizontal diplopia. 2 in children, abducens nerve palsy has been associated with viral infections, including epstein-barr and enterovirus, as well as with vaccinations. Sixth nerve palsy is also referred to as lateral rectus palsy, cranial nerve VI palsy, cranial mononeuropathy VI, or abducens nerve palsy. None of the patients had a facial nerve paresis or evidence of a trigeminal sensory neuropathy.
