Kayser-Fleischer-like ring in a cryptogenic cirrhosis

Area of Science:

• Ophthalmology
• Hepatology
• Medical Diagnostics

Background:

• Cryptogenic cirrhosis presents diagnostic challenges.
• Kayser-Fleischer rings are pathognomonic for Wilson's disease.
• Hepatic encephalopathy can manifest with neurological symptoms.

Observation:

• A patient with cryptogenic cirrhosis exhibited corneal pigmentation rings.
• These rings were visually indistinguishable from Kayser-Fleischer rings on slit-lamp examination.
• The patient presented with hepatic encephalopathy, including confusion, tremor, and slurred speech.

Findings:

• Despite neurological symptoms suggestive of Wilson's disease, the diagnosis was ruled out.
• Urinary copper excretion and hepatic copper concentrations were below the established ranges for symptomatic Wilson's disease.
• The corneal pigmentation was characterized as Kayser-Fleischer-like rings due to indeterminate etiology.

Implications:

• This case highlights the importance of considering differential diagnoses in patients with cirrhosis and corneal findings.
• Kayser-Fleischer-like rings may occur in conditions other than Wilson's disease.
• Further investigation may be needed to elucidate the cause of such rings in non-Wilson's disease patients.
