Hereditary Tyrosinemia Type 1—A Rare Disease with Typical Radiological Features: Case Report and Review of Literature

Abstract

Hereditary tyrosinemia type 1 is one of the many inborn errors of metabolism associated with tyrosine catabolism. It is a rare disease with its incidence or prevalence in India unknown. The cascading alternate metabolism results in characteristic injury patterns to the liver, kidneys, and the central nervous system, with resultant classical radiological findings. Identifying this constellation of imaging features by a radiologist may help in arriving at a diagnosis and help referring physicians in performing appropriate biochemical tests and instituting early treatment. These usually present with chronic liver failure and are extensively evaluated for other causes of liver failure. We present a case type 1 hereditary tyrosinemia with characteristic radiological features and highlight its pathophysiology to understand the basis of these imaging findings.
