Tangential sulcal echoes. Potential pitfall in the diagnosis of parenchymal lesions on cranial sonography.
The sonographic appearance of normal neonatal cerebral sulci may mimic that of significant intracranial pathology. An echogenic pseudolesion can be seen when a sulcus is imaged through its long axis. Criteria are discussed for the differentiation of this normal variant from true parenchymal lesions with their attendant serious clinical implications.
