Abstract
|
|
|
|
Visceral larva migrans (VLM) syndrome is a clinical manifestation of systemic organ involvement by Toxocara species. VLM with involvement of the bladder and liver is a rare finding. A 62-year-old woman presented with diffuse bladder wall thickening and multiple liver masses with peripheral eosinophilia and urinary symptoms. We considered malignancy or eosinophilic cystitis through clinical manifestations and imaging findings. However, no suspicious malignant lesions were observed on cystoscopy and liver mass biopsy revealed the presence of eosinophilic necrotizing granuloma without malignant cells. Anti-Toxocara antibodies were detected by western blotting and the patient was diagnosed with VLM syndrome. After taking prednisolone, urinary symptoms disappeared. On abdominal CT scan taken after three months, the size of multiple liver masses and bladder wall thickening had decreased. VLM syndrome should be suspected in patients with an atypical imaging pattern and peripheral eosinophilia.
