Clinical Profile and Long-Term Outcomes in Pediatric Cavernous Sinus Thrombosis

Background: Pediatric cavernous sinus thrombosis (CST) is a rare condition with limited data regarding its clinical characteristics and long-term outcomes. The objective of this study was to describe the clinical and radiologic features, diagnostic evaluation, management, and long-term prognosis and to identify clinical variables associated with long-term outcomes in pediatric CST.

Methods: A retrospective chart review of patients younger than 18 years diagnosed with a CST between 2004 and 2018 at a single center was conducted.

Results: We identified 16 (M:F = 10:6) children with CST with a mean age of 7.6 years (10 days to 15 years) and average follow-up duration of 29 months (3 weeks to 144 months). The most common symptom and examination finding at presentation was eyelid swelling (n = 8). Six patients had bilateral CST. The most common etiologies were sinusitis (n = 5) and orbital cellulitis (n = 5). Treatments included antibiotics (n = 14), anticoagulation (n = 11), and surgery (n = 5). Only one patient died due to intracranial complications. Twelve patients had a normal examination at follow-up. None of the clinical variables including age (P = 0.14), gender (P = 0.09), use of antibiotics (P = 1.00) or anticoagulation (P = 1.00), surgery (P = 0.28), parenchymal abnormalities (P = 0.30), additional cerebral venous thrombosis (P = 0.28), and early versus late commencing of anticoagulation (P = 1.00) were significant when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.

Conclusions: Our study is one of the largest cohorts with the longest follow-up data for the pediatric CST. Most of our patients had favorable outcomes at follow-up. We found no statistical difference between clinical variables when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.
