Congenital hydrocephalus as a rare association with ligneous conjunctivitis and type I plasminogen deficiency

Neuropediatrics. 2005 Apr;36(2):108-11. doi: 10.1055/s-2005-837657.


Severe type I plasminogen deficiency is the underlying cause of ligneous conjunctivitis (LC). Furthermore, pseudomembranes may also be found on other mucous membranes (gastrointestinal tract, bronchial system, genital tract). In very rare cases, congenital hydrocephalus has been associated with the more severe forms of the disease and may even precede LC. The pathophysiological mechanism is unclear at present. It is advisable to look for plasminogen deficiency in patients with congenital hydrocephalus, because obstruction of ventriculoperitoneal shunts is possible when such a condition is overlooked. Here, we report a case of LC with hydrocephalus. This report reemphasizes the association of LC with hydrocephalus which is not well known.
