Myositis is a rare unknown inflammatory disorder of the skeletal muscle tissue. Generalized inflammatory myopathies, polymyositis, and dermatomyositis have been reported during pregnancy. Isolated orbital myositis in pregnancy has not been previously described in the literature. The authors report a case of left isolated orbital myositis in a primigravida at 38 weeks gestation affecting the patient's left lateral rectus muscle. MRI of the orbit was consistent with the diagnosis. She showed remarkable clinical improvement with oral corticosteroids therapy.

BACKGROUND: Acute ophthalmoparesis without ataxia was designated as 'atypical Miller Fisher syndrome' as it presents with progressive, relatively symmetrical ophthalmoplegia, but without ataxia nor limb weakness, in the presence of anti-GQ1b antibody. Idiopathic intracranial hypertension is characterized by signs of raised intracranial pressure occurring in the absence of cerebral pathology, with normal composition of cerebrospinal fluid and a raised opening pressure of more than 20 cmH2O during lumbar puncture. We aim to report a rare case of acute ophthalmoplegia with co-occurrence of raised intracranial pressure.
CASE DESCRIPTION: A 28-year-old gentleman with body mass index of 34.3 was referred to us for management of double vision of 2 weeks duration. His symptom started after a brief episode of upper respiratory tract infection. His best corrected visual acuity was 6/6 OU. He had bilateral sixth nerve palsy worse on the left eye and bilateral hypometric saccade. His deep tendon reflexes were found to be hyporeflexic in all four limbs. No sensory or motor power deficit was detected, and his gait was normal. Plantar reflexes were downwards bilaterally and cerebellar examination was normal. Both optic discs developed hyperaemia and swelling. Magnetic resonance imaging of brain was normal and lumbar puncture revealed an opening pressure of 50 cmH2O. Anti-GQ1b IgG and anti-GT1a IgG antibody were tested positive.
CONCLUSION: Acute ophthalmoparesis without ataxia can present with co-occurrence of raised intracranial pressure. It is important to have a full fundoscopic assessment to look for papilloedema in patients presenting with Miller Fisher syndrome or acute ophthalmoparesis without ataxia.
