[Solitary hepatic cyst. Presentation of a case diagnosed in neonatal period].
Hospital Infantil Universitario Virgen de la Arrixaca, Murcia.Cirugía pediátrica: organo oficial de la Sociedad Española de Cirugía Pediátrica 11/1992; 5(4):228-30.
We reported one case of hepatic solitary cyst, in an infant seven days old. The precocious diagnostic was supported by the presence of an abdominal cyst mass in prenatal period. Different diagnostic and therapeutic consideration are made.

ABSTRACT: Antenatally detected liver cysts are rare; their diagnostic accuracy is unknown, and their management is controversial. This study assessed the natural history of these lesions. We conducted a retrospective review of infants with isolated intrahepatic cysts that were detected antenatally. Data are expressed as median (range). Fifteen infants presented during the period 1991-2004 with an antenatally detected liver cyst. Their gestational age at detection was 22 (18-34) weeks, and the maximum diameter of their cyst was 23 (10-120) mm. Serial scans, which were performed in 9 fetuses, showed cyst enlargement in 5 cases, diminution in 1 case, and no change in 3 cases. In utero percutaneous aspiration was required in 1 infant. Three infants underwent postnatal surgery. One fetus (postfetal intervention) had a subtotal excision of a large subcapsular cyst filling the abdominal cavity on day 2. Another infant required partial excision and marsupialization (complex cyst arising from segment IV) at 5 months, and a third infant underwent a cyst cholecystostomy at 4 months. Postnatal investigations (including hepatic scintigraphy) suggested that the remaining lesions were either simple parenchymal (n = 10) or isolated intrahepatic choledochal (ie, type V; n = 2) cysts. The median follow-up for these patients was 44 (27-167) months. Serial postnatal ultrasonography showed cyst diminution in 4 cases, an enlargement in 1 case, and no dimensional change in 7 cases. Most antenatally detected liver cysts appear to be simple and of parenchymal origin and do not require fetal intervention. Their postnatal history is variable, but regression without treatment is seen in most cases.
