Posterior reversible encephalopathy syndrome is a clinico-neuroradiologic entity with typical symptoms and symmetric high-signal intensity lesions in the bilateral parietooccipital lobes on T2-weighted or fluid-attenuated inversion recovery magnetic resonance imaging. In this presentation, we report a case of posterior reversible encephalopathy syndrome who was admitted to our emergency department because of seizure and deterioration of consciousness. The aim of this presentation is to alert the emergency physicians about one of the hypertensive emergencies with neurologic symptoms associated with hypertension.

A seminal vesicle cyst is a rare etiology of pelvic pain. However, its rarity may result in oversight or misinterpretation if the radiologist or emergency physician is unfamiliar with this entity. Seminal vesicle cysts may cause pelvic pain because of mass effect, infection, internal hemorrhage, or urinary and bladder obstruction. ⋯ Recognition of the imaging findings of seminal vesicle cysts is necessary to allow prompt, accurate diagnosis. Therefore, emergency physicians and radiologists interpreting examinations from the emergency department should be familiar with these imaging findings because seminal vesicle cysts may be the etiology of pelvic pain and the patient may benefit from urologic consultation and cyst aspiration or resection. The purposes of this article are to provide examples of pelvic pain caused by seminal vesicle cysts, illustrate the key imaging findings on computed tomography, and briefly review the literature.

Case Reports
Delayed herniation of intra-abdominal contents after blunt right-sided diaphragm rupture.
Right diaphragmatic hernia is a rare injury (0.25%-1%) after blunt abdominal trauma. The diagnosis may be delayed and achieved years after the trauma. We currently report a case of a 48-year-old man who presented to the emergency department at Far Eastern Memorial Hospital, New Taipei City, Taiwan, demonstrating signs of herniation of the right diaphragm. ⋯ The diagnosis was further confirmed through thoracoabdominal computed tomography. The diaphragmatic hernia was subsequently repaired via abdominal approach. For patients with a history of prior thoracoabdominal trauma with complaints of new abdominal pain, a delayed diaphragmatic hernia should be considered.

Patients who present to the emergency department (ED) with symptoms of potential acute coronary syndrome (ACS) can be safely discharged home after a coronary computed tomographic angiography (CTA) with a negative result. However, the duration of time for which a negative coronary CTA scan result can be used to inform decision making when patients have recurrent symptoms is not known. ⋯ Repeated imaging potentially may not be warranted within 2 years of a negative coronary CTA result. The low rate of progression from subcritical to critical disease is consistent with observations in patients who have had prior negative cardiac catheterizations.

Alcoholism is the major cause of electrolyte and acid-base imbalance and nutrition deficiency. Ketoacidosis is one of major advised effect on alcoholism. Marchiafava-Bignami disease, a rare alcohol-related disorder, characterized by altered mental status, seizure, and multifocal central nervous system signs, which results from progressive demyelination and necrosis of corpus callosum. ⋯ Alcoholic ketoacidosis coincided with acute Marchiafava-Bignami disease had been confirmed by biochemistry examination and cranial magnetic resonance imaging. Aggressive hydration with 5% dextrose in normal saline and intravenous vitamin B complex were administered. The patient's symptoms completely recovered after ketoacidosis has been corrected 2 days later.
