Angiography-negative childhood primary angiitis of the central nervous system diagnosed by open brain biopsy: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Childhood primary angiitis of the central nervous system (PACNS) is rare and has been poorly defined, which makes it difficult to diagnose and treat. Herein, we report a case of childhood PACNS that was diagnosed by open brain biopsy. Clinical symptoms and radiologic findings improved after combination treatment with steroid and cyclophosphamide. In this case, a 16-year-old, previously healthy, adolescent male complained of headache, seizure, and right-side weakness with hypoesthesia. Brain magnetic resonance imaging (MRI) showed multifocal, high-signal intensity lesions on T2-weighted scans with patch contrast enhancement. The clinical symptoms improved after intravenous steroid pulse therapy (methylprednisolone, 1,000 mg/day for 3 consecutive days) and subsequent oral steroid maintenance. However, follow-up brain MRI showed aggravation of the previous lesions. Open brain biopsy of the left parietal lobe showed infiltration of lymphoplasma cells to the vessel walls with parenchymal necrosis, consistent with PACNS. The patient received four monthly intravenous cyclophosphamide (1,000 mg/dose at each cycle) treatments along with oral steroid maintenance. After treatment, he was symptom-free, and follow-up MRI revealed marked lesion improvements. This case suggests the important role of brain biopsy and aggressive immunosuppressive treatment in diagnosis and management of childhood PACNS.
