Primary angiitis of the central nervous system in children - case series
Pediatric Rheumatologyvolume 9, Article number: P94 (2011)
Primary angiitis of the central nervous system (PACNS) is a rare inflammatory brain disease with variable clinical manifestations. Only limited data exist with regard to efficient diagnostic and therapeutic algorithms and disease outcomes in children.
To characterize clinical features, neuroimaging findings, treatment and disease outcome in a small cohort of Czech children with PACNS.
A retrospective chart review of patients referred for suspected PACNS was performed. MRI lesions detected at disease onset were classified as unilateral (UL), bilateral (BL), unifocal (F), multifocal (MF), angiography (MRA and/or conventional) positive (medium/large vessel disease) or negative (small vessel disease). According to the evolution of clinical manifestations and neuroimaging PACNS was classified as progressive or non-progressive. Data on treatment and follow-up were collected.
Seven female patients (all Caucasian, mean age 14,8 years, median F/U 2 years) were identified (Table). Three had favourable outcome. Four (1,2,5,7) had progressive disease resulting in significant impairment. Their mean interval from onset to diagnosis was 7 months. All 4 had multifocal lesions, 2 had negative angiography, 3 did not receive any anti-inflammatory therapy early in the disease course.
Unfavourable outcome of this patient cohort reflects potential severity as well as low physicians awareness of PACNS resulting in diagnostic delay and insufficient therapy. A working group of paediatric specialists is being formed in the Czech Republic in order to establish diagnostic and therapeutic algorithms in close interdisciplinary and multicenter collaboration.
