Septic arthritis of the facet joint is an extremely rare condition, even more in young immunocompetent patients. There have been approximately only 40 cases of this entity reported worldwide. Here, the authors present a 16-year-old male patient with lower back pain, fever, and cephalea. Blood cultures and cerebrospinal fluid analysis confirmed methicillin-sensitive Staphylococcus aureus infection, and magnetic resonance imaging showed septic arthritis of the lumbar left facet joint L3 and epidural abscess. Intravenous oxacillin was administered, and the patient improved. No other treatment was required.
Pituicytoma is a rare tumor that arises from the glial cells of the neurohypophysis. For a long time, it was believed that pituicytomas only appeared in adults. Currently, at least three cases of this entity occurring in children have been reported in the literature. The aim of the present report is to describe the case of a 5-year-old girl who presented to the emergency department with visual disturbances, and the diagnosis was a recurrent pituicytoma. Therefore, the clinical presentation, the radiological features of the tumor, and the corresponding surgical management are described. Additionally, a brief review of the management of this unusual entity was performed.

ResumoO pituicitoma é um tumor raro que surge das células gliais da neurohipófise. Durante muito tempo, acreditou-se que os pituicitomas só aparecessem em adultos. Atualmente, pelo menos três casos desta entidade ocorrendo em crianças foram relatados na literatura. O objetivo do presente artigo é descrever o caso de uma menina de 5 anos que chegou à emergência com distúrbios visuais, e o diagnóstico foi um pituicitoma recorrente. A apresentação clínica, as características radiológicas do tumor, e o correspondente manejo cirúrgico foram, portanto, descritos. Além disso, foi realizada uma breve revisão do tratamento desta entidade incomum.
