Neonatal adrenoleukodystrophy is an inborn error of peroxisome biogenesis. It is part of the Zellweger spectrum. It has been linked with multiple genes (at least five) associated with peroxisome biogenesis, and has an autosomal recessive pattern of inheritance. References

Visceral solitary IMF tumors that cause significant tissue injury, are located in vital areas, and/or are life-threatening have been treated by surgical excision or, if surgery is deemed inappropriate, are treated with drugs and/or radiation therapy as indicated in the following section on multiple tumors (with visceral involvement). Surgical excision has also be used if the diagnosis of the tumor is in doubt. In rare cases, aggressive IMF tumors have recurred after regressing and required further observation and/or treatment. Overall, the prognosis in almost all cases of solitary IMF is good to excellent. Multiple tumors (no viscera involvement)
Multiple tumors (no viscera involvement) also may regress spontaneously and carry a good to excellent prognosis even when they invade local tissues. However, neonates presenting with multiple IMF tumors should undergo a through examination including medical imaging tests to determine the extent of their disease, particularly with respect to determining if a visceral tumor(s) is present and therefore that the proper diagnosis is multiple tumors (with viscera involvement). The treatment of multiple tumors (no viscera involvement) is similar to that used for solitary IMF tumors. Multiple tumors (with viscera involvement)
Individuals with multiple tumors (with viscera involvement) have numerous tumors one or more of which are located in and often injure a vital internal organ and may be life-threatening. Cases in which one of the tumors is in a vital organ and seriously symptomatic have been successfully treated with surgical resection.
