Abstract
INTRODUCTION: Cavum septi pellucidi (CSP) cysts have a very low incidence (0.04%). Symptomatic patients usually present aspecific symptoms. For this reason, the management of these patients is still debated. MATERIALS AND METHODS: We selected the case of a ten year old patient, with a clinical history of frontal morning headaches and difficulty in concentration. Brain MRI documented a septum pellucidum cyst and a moderate biventricular dilation. We submitted the case, and a questionnaire concerning indications to surgery and management options to an international group of 54 pediatric neurosurgeons, analyzing the results and comparing them with the current literature. RESULTS: The majority of the participants (50%) indicated as appropriate at the early stage only a clinical observation. In case of persistence of clinical symptoms, 58% opted for intracranial pressure (ICP) monitoring, which, if raised, was considered by 91% as an adequate indication to proceed with surgical treatment. A total of 98% of the participants indicated endoscopic fenestration of the cyst as the preferred surgical strategy. CONCLUSIONS: The management of symptomatic patients with CSP cyst is controversial. Our results suggest that in most of the patients with aspecific symptoms, clinical observation and eventually ICP monitoring are adequate to identify patients for surgery.
