Clinical features of pediatric patients with cerebral venous sinus thrombosis after isolated head trauma.

OBJECTIVE: An association between blunt head trauma and cerebral venous sinus thrombosis (CVST) has been recognized, but its symptoms are nonspecific and the duration of symptoms remains unclear. Anticoagulation therapy is not considered necessary in most cases of traumatic CVST; however, this is controversial. The aim of this study was to describe the clinical characteristics and outcomes of children with CVST after isolated head trauma. METHODS: The records of pediatric patients with isolated head trauma admitted for observation at 3 medical centers between January 2018 and May 2023 were reviewed retrospectively. CVST was diagnosed on MR venography (MRV). Clinical presentation, therapeutic management, and outcomes were evaluated in patients who had follow-up MRV. RESULTS: Of 260 pediatric patients with head trauma admitted to the 3 hospitals, 26 patients underwent MRV and 8 (30.8%) were diagnosed with CVST. One patient was treated with heparin, while the others received conservative treatment. All patients were discharged home asymptomatic. MRV performed during follow-up displayed complete recanalization in all cases, except for 1 case with partial recanalization. The median hospital stay was longer in patients with CVST than in those without CVST (9.5 vs 3.0 days, p = 0.001). CONCLUSIONS: The length of stay of pediatric patients with traumatic CVST was prolonged compared with those without CVST, but most patients had good outcomes with spontaneous recanalization following conservative treatment.

Acute central nervous system vasculitis as a manifestation of neurosarcoidosis: A case report and literature review.

Neurosarcoidosis (NS) affects various sites of the central nervous system, including the cranial nerve, meninges, brain parenchyma, hypothalamus, and pituitary gland. NS rarely causes intracerebral vasculitis and subsequent strokes, or cerebral infarction and hemorrhage, which are associated with high mortality. Herein, we report a 71-year-old woman's case of stroke associated with NS, which showed aggressive cerebral vasculitis with brain herniation; it was resolved with corticosteroid therapy after accurate histopathological diagnosis. This case highlights the necessity of expecting NS to sometimes follow an aggressive course, presenting with vasculitis. Most patients with NS satisfactorily respond to corticosteroids, but this is not always the case. In cases of unfamiliar ischemic or hemorrhagic lesions, the possibility of NS must be considered.
