RESUMO
A 23- year-man post female to male (FTM) gender transition was found to have bilateral papilloedema at a routine optician visit. The patient was referred on for formal ophthalmological and neurological assessments. Optical coherence tomography (OCT) confirmed the presence of bilateral papilloedema. The patient was entirely asymptomatic and had no medical history. He took testosterone intramuscularly once per month. Neurological examination was otherwise normal. Investigations including routine blood panels, CT brain, MRI brain and cerebral MR venogram were all normal. Lumbar puncture yielded cerebrospinal fluid (CSF) normal in appearance but demonstrated raised intracranial pressure. In the absence of other causative aetiologies a diagnosis of idiopathic intracranial hypertension (IIH) was made. Treatment was commenced with acetazolamide and the patient was discharged with outpatient ophthalmological and neurological follow-up.

A 24-year-old woman presented with bilateral blurring of her distance vision and 'dizzy spells'. She had no other neurological symptoms or medical history. She consulted an optometrist, and optical coherence tomography (OCT) was performed, which demonstrated papilloedema. She was referred to the local eye clinic for assessment and from there was referred for neurological assessment.Her initial investigations revealed no abnormalities, and brain imaging was reported to be normal. In the absence of an alternative diagnosis, idiopathic intracranial hypertension (IIH) was considered and a lumbar puncture was performed. This showed elevated protein but normal cerebrospinal fluid (CSF) pressure. MRI of the brain the next day revealed a large cerebellopontine lesion in keeping with vestibular schwannoma. She was referred to neurosurgery for operative management.This case highlights three interesting points: the aetiology of her papilloedema without raised intracranial pressure, the decision to perform a lumbar puncture in suspected IIH and community OCT as a clinical adjunct.

A 26-year-old cachectic man presented with an altered mental status. He was agitated, tremulous, hyperthermic and diaphoretic with largely dilated pupils. Collateral history revealed acute ingestion of 3,4-methylenedioxymethamphetamine on a background of chronic drug abuse. His condition deteriorated requiring sedation and intubation with transfer to the intensive care unit. A diagnosis of serotonin syndrome was made, based on his findings in keeping with the Hunter criteria, and he was treated with supportive management during a resultant and briefly sustained delirium. With gradual resolution of his agitated state, further questioning and blood work a concurrent, and potentially contributory, thyrotoxicosis was revealed. The patient was commenced on treatment for this with urgent outpatient follow-up with both a local otolaryngologist and endocrinologist for consideration of further treatment.
