Neuromotor spectrum of periventricular leukomalacia in children born at term

The spectrum of neuromotor abnormalities of term children with periventricular leukomalacia (PVL) has never been specifically defined. We report 12 term children with PVL to delineate its long-term clinical correlates. A retrospective review of a standardized computer database and files of a single pediatric neurologist during a 7-year period was performed. The imaging studies were reviewed independently by two neuroradiologists. The mean age of the patients at the initial neurologic assessment was 24. 4 months (range 5-60); nine were males. The reason for the assessment was developmental delay in 10 (83.3%), seizure in one, and attention-deficit-hyperactivity disorder in one. Three children (25%) had normal motor examinations, three (25%) were hypotonic, three (25%) had spastic diplegia, two (16.7%) had spastic quadriplegia, and one (8.3%) had fine-motor abnormalities. Nine children (75%) had developmental delay (severe global delay in six), and two children (16.7%) had epilepsy; electroencephalograms were abnormal in six (50%). PVL was mild in five (41.7%), moderate in two (16.6%), and severe in five (41.7%) children. Four of eight children with global developmental delay had enlargement of cerebral sulci in addition to white matter changes. PVL in term children presents with a spectrum of neurologic abnormalities, particularly developmental delay and heterogeneous motor findings not limited to classic spastic diplegia. The clinician should consider the diagnosis of PVL in the context of term children with developmental delay and motor abnormalities, even in the absence of perinatal difficulties.
