Familial visceral neuropathy as part of a diffuse neuronal syndrome: four fatal cases in one sibship.
Familial visceral neuropathy is a rare cause of chronic intestinal pseudo-obstruction. It is characterized by progressive destruction of the gastrointestinal myenteric plexus resulting in dysmotility and associated early satiety, post-prandial bloating, recurrent nausea and vomiting, abdominal distension, chronic diarrhea, weight loss, and malnutrition. In its varying forms, there may be neuronal destruction in other parts of the peripheral and central nervous system. We report on four siblings who presented in their third or fourth decades with initial clinical features of chronic intestinal pseudo-obstruction and eventual progressive diffuse neuronal disease, characterized by leukoencephalopathy and peripheral neuropathy. Within 5 yr of presentation, all four patients died from inanition and sepsis, despite aggressive nutritional support. Their clinical and pathological features are characteristic of familial visceral neuropathy of the autosomal recessive form. This presentation may represent a unique syndrome characterized by a tetrad of polyneuropathy, ophthalmoplegia, leukoencephalopathy, and intestinal pseudo-obstruction.
