We report a 36-year-old man who developed a large epidural and paraspinal abscess as a complication of infliximab therapy being used for underlying Crohn's disease. Cultures of the collection grew methicillin-susceptible Staphylococcus aureus, and treatment consisted of abscess drainage, prolonged intravenous and oral flucloxacillin and temporary withholding of his infliximab. While infection-related complications are well described with infliximab therapy, this is the first description of a large paraspinal abscess with epidural extension.

Lemierre's syndrome is a potentially severe disease characterised by suppurative thrombophlebitis of the internal jugular vein and subsequent disseminated septic embolisation. The profile of this syndrome declined in the mid-20th century, coinciding with the introduction of antibiotics. Currently, lack of awareness of this condition delays appropriate treatment and worsens prognosis. We report a case of Lemierre's syndrome in a 12-year-old girl.

A young man with severe traumatic brain injury and refractory intracranial hypertension was treated with a barbiturate coma. A rare side effect of barbiturates is dyskalaemia. The dyskalaemia presented with acute hypokalaemia that quickly became hyperkalaemia. ⋯ The correct diagnosis and treatment of barbiturate dyskalaemia is essential in providing care. Clinicians treating patients with barbiturates need to be aware of this rare side effect. Our patient was quickly and correctly treated for the dyskalaemia and suffered no complications related to this side effect.

Posterior reversible encephalopathy syndrome (PRES) is a cliniconeuroradiological syndrome characterised by a unique reversible pattern on imaging and total regression of clinical symptoms and signs. We describe an unusual case of PRES with isolated pontine involvement with coincidental acute ischaemic stroke in a 60-year-old man who presented with headache, unsteadiness of gait, blurred vision and elevated blood pressure. ⋯ A diagnosis of PRES was considered most likely after exclusion of other differentials and the patient was started on antihypertensive treatment as for hypertensive encephalopathy. He became asymptomatic after controlling blood pressure and the follow-up MRI scan at 3 weeks showed complete resolution of the pontine high signals which confirmed the diagnosis of PRES.

Case Reports
Cryptogenic adrenal infarction: a rare case of unilateral adrenal infarction in a pregnant woman.
Adrenal infarction is a rare event, especially in pregnancy. The diagnosis is challenging because patients present with acute abdomen and initial workup are usually unrevealing. ⋯ MRI and contrast-enhanced CT scan revealed a non-haemorrhagic infarct of the right adrenal gland. Our case highlights the importance of considering this rare diagnosis in the differential for a pregnant woman with acute abdomen without any obvious surgical cause.
