Four examples of grossly mineralized lesions of the brain, causing seizures, are described; they include 2 hamartomas, a choristoma (novel associations), and an idiopathic "brain stone." Each was detectable with routine roentgenograms, and the seizures were ameliorated by surgical therapy.
Thirteen cases of posterior fossa arachnoid cyst are described. Presenting features were usually headache, vomiting, lethargy, and delayed development in infants. Association with congenital defects is sometimes noted. The cysts are considered to result from abnormalities occurring in foetal life.
Two cases with the pathologic changes of congenital hepatic fibrosis are described in asymptomatic adults without renal anomaly, Foci of necrosis adjacent to abnormal portal areas suggest that the lesion may not be congenital. It is also suggested that this variant of the disorder may be more common than generally recognized.
