# Computed tomography angiography of liver alveococcosis: a case report

## TL;DR

A rare case of liver alveococcosis in Uzbekistan is diagnosed using contrast enhanced CT, helping to differentiate it from other liver conditions.

## Contribution

This case report highlights the diagnostic utility of contrast enhanced CT in identifying liver alveococcosis in a rare geographical context.

## Key findings

- Contrast enhanced CT successfully identified liver alveococcosis in a 33-year-old woman from Uzbekistan.
- CT helped differentiate alveococcosis from other liver pathologies like hemangioma and hepatocellular carcinoma.
- Microscopic examination confirmed the presence of parasitic structures consistent with alveococcosis.

## Abstract

Alveococcosis, helminthiasis caused by the larvae of Alveococcus multilocularis, is characterized by the formation of parasitic nodes in the liver. This clinical case is a rare occurrence of liver alveococcosis in Uzbekistan.

We present a case of a 33-year-old Asian woman from Uzbekistan who complained of discomfort in the epigastric region and right hypochondrium, along with general weakness. She had been experiencing symptoms for 5 months when a routine ultrasound examination revealed a structural formation in the liver. Patient was investigated by using contrast enhanced computed tomography (CT) and diagnosed with liver alveococcosis with multiple lesions. Patient underwent diagnostic laparotomy with obtaining gross specimen, biomaterial was examined microscopically and found that there were small fragments of fibrous tissue determined together with small groups of cystic formations and walls consisted of chitin. Moreover, contrast enhanced CT allowed us to differentiate liver alveococcosis from cavernous hemangioma, hepatocellular carcinoma, and liver metastases from unknown source.

Contrast enhanced CT plays a major role in differentially diagnosing liver alveococcosis and makes it the first line method of choice for the consideration of the future treatment and surgical interventions.
