CILIATED HEPATIC FOREGUT CYST - REPORT OF A CASE WITH FINDINGS ON FINE-NEEDLE ASPIRATION

Ciliated hepatic foregut cyst (CHFC) is an uncommon cystic lesion of t he liver. It is analogous in nature and pathogenesis to the bronchial cysts that occur in the mediastinum. We report a case of CHTC diagnose d on fine needle aspiration (FNA) with a discussion of the cytologic f indings and features and a review of the literature. Abdominal compute d tomography (CT) defected the lesion during a workup for metastatic s quamous cell carcinoma of the cervix in a patient with an intrauterine contraceptive device and uterine Actinomyces infection. Subsequent CT -guided FNA produced clear, viscid material that revealed numerous mac rophages and scattered ciliated columnar cells within the mucinous bac kground. The cytology and radiologic findings were essentially similar to those of a bronchial cyst and did not conform to any of the findin gs in generally known lesions of the liver. Awareness of this rare hep atic lesion will result in an accurate and definitive diagnosis by gui ded FNA biopsy and avoidance of surgical exploration and excision biop sy.
