Four weekly doses of rituximab were administered. Follow-up colonoscopy performed one month after treatment revealed slight improvement in the rectal lesion without remnant histological evidence of a MALT lymphoma. In addition, the stricture showed marked improvement, and the colonoscope could pass easily through the stricture site.

To compensate for these changes, neurotransmitter hormone changes and metabolic abnormalities occur, which cause complications in organs other than the liver. A hepatic hydrothorax is fluid accumulation in the pleural space resulting from increased portal pressure.

Understanding these mechanisms is crucial for the timely identification and management of HRS. The diagnosis of HRS is primarily clinical and relies on specific criteria that consider the exclusion of other causes of renal dysfunction. The management of HRS comprises two main approaches: vasoconstrictor therapy and albumin infusion, which aim to improve renal perfusion and mitigate the hyperdynamic circulation often seen in advanced liver disease.
