POCUS to Diagnose a Large Urethral Stone Causing Urinary Retention: A Case Report.

Background: Ultrasound is routinely used in the diagnosis of renal calculi and resulting hydronephrosis. However, its utility in the diagnosis and management of urethral calculi is less well understood. The ability to rapidly diagnose urethral calculi using point of care ultrasound (POCUS) would be useful in the emergency department (ED) to improve patient outcomes and avoid more invasive investigations.

Lessons from a case of osteopetrosis oxycephaly and Chiari type I malformation: a case report.

We report a child with osteopetrosis, oxycephaly and Chiari type I malformation who presented with raised intracranial pressure. During cranial expansion surgery the patient developed sudden cardiac arrest which we believe was probably related to the Chiari malformation. The case highlights a previously unrecognized association between osteopetrosis, craniosynostosis and a persistently open fontanelle at age 4 years.

Brain abscess formation as a CSF shunt complication: a case report.

The formation of a brain abscess as a result of a cerebrospinal fluid shunt complication is extremely rare in the literature with only 7 cases reported in the last 20 years. We report a patient that developed a brain abscess adjacent to a functioning ventricular catheter in the presence of shunt infection by another pathogen. Clinicians should consider this complication in any shunted patient with clinical features of infection and suggestive changes on imaging however subtle.
