Atypical presentation of Prader-Willi syndrome with cerebral venous thrombosis: association or fortuity?
Publication types: Case Reports ; Journal Article --- Old month value: Aug
A newborn female born at term was admitted at 28 hours for seizures and generalized hypotonia. Cerebral ultrasound showed a right temporal echogenic lesion confirmed on MRI and thought to be secondary to thrombosis of the vein of Labbé. The EEG showed epileptic discharges over the right temporal region. Extensive thrombotic studies revealed a transiently decreased PTT consistent with a prothrombotic state. The hypotonia did not resolve after the acute phase as expected, raising the possibility of another underlying cause. Because of a peculiar phenotype with almond-shaped eyes and bitemporal depression, Prader-Willi syndrome (PWS) was suspected. Methylation analysis confirmed PWS, FISH analysis excluded a deletion in 15q11-q13, maternal uniparental disomy (UPD) was confirmed. To our knowledge, this is the first report of the association of a neonatal venous thrombosis and a PW Syndrome.
