Congenital herpes simplex type II infection with extensive hepatic calcification, bone lesions and cataracts: complete postmortem examination.

True congenital herpes simplex viral (HSV) infections have been reported infrequently and have been associated with various 'congenital' malformations. Microcephaly, microphthalmia, intracranial calcifications, chorioretinitis, congenital heart disease and abnormal digits have been associated with presumed congenital HSV infection. This report describes the clinical and pathological features of an infant with a congenital type-II HSV infection. In addition to the findings previously reported with this form of HSV infection, extensive hepatic calcifications, osseous lesions and cataracts were observed for the first time. The effect of congenital HSV infection on the developing central nervous system is discussed.

Cytomegalovirus endolabyrinthitis.

A premature male infant, who died 22 days after birth with hyaline membrane disease, was found to have had cytomegalic inclusion disease at autopsy. Histopathologic examination of the temporal bones showed cytomegalovirus (CMV) infection of the entire endolabyrinth without involvement of the neural and sensory structures. These findings support the thesis that late gestational or perinatal fetal CMV infection results in an endolymphatic labyrinthitis. We hypothesize that blood-borne virus passes from the stria vascularis into the endolymphatic spaces and infects the nonneurosensory epithelium. This pattern of infection differs from the perilabyrinthitis of human varicellazoster and experimentally produced mouse CMV.
