We report the case of a 6-year-old boy presenting with intention tremor. CT and MR scanning showed a large thalamic cyst. Stereotactic tapping of this cyst was carried out as the first step in surgical management. Following drainage of the cyst the tremor disappeared, but recurred 18 months later. Repeat MRI showed that the thalamic cyst had refilled. As the initial tapping of the cyst had resulted in effective but only transient clinical improvement a cysto-peritoneal shunting procedure was performed. The clinical symptoms again disappeared and the child has now remained tremor free for 3 years.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
