Summary: | Giant hepatic hemangiomas (GHHs) are those that are larger than 4cm in size.
The aim of this study was to describe GHH clinical findings, their risk factors, diagnostic approach and management, and to compare these data with those of conventional hemangiomas.
We performed a retrospective analysis of patients diagnosed with hemangiomas, whether by imaging studies or histopathology, at our hospital within the time frame of 1990-2008. The medical records of each patient were reviewed to obtain clinical and surgical data.
Of the 57 patients with liver hemangioma, 41 (72%) were women and 32 (56%) had GHH. Liver hemangioma median size was 4.49cm. In regard to the patients with GHH, 31.2% were asymptomatic and when symptoms presented, pain was the most common. Both symptoms and oral contraceptive exposure were more common in the GHH patients. Nine patients with GHH underwent surgery: 2 open biopsies due to diagnostic uncertainty, one enucleation, and 6 resections.
GHHs are more prevalent in women and when symptomatic, pain is the most frequent complaint. Diagnosis is usually made through imaging studies, but when there is diagnostic doubt, surgical exploration is sometimes needed. Oral contraceptive use is most likely more of a risk factor for GHH than for conventional hemangioma, but this association needs to be studied further.
Los hemangiomas hepáticos gigantes (HHG) son aquellos con un tamaño superior a 4cm.
El objetivo de este estudio fue describir los hallazgos clínicos del HHG, sus factores de riesgo, el abordaje diagnóstico y el manejo, y comparar esta información con la del hemangioma convencional.
Se realizó un análisis retrospectivo del periodo 1990-2008 de pacientes con diagnóstico, sea por imagen o histopatología, de hemangioma hepático atendidos en nuestro hospital. De cada paciente se revisó su expediente para extraer información médica y/o quirúrgica.
De 57 pacientes con hemangioma hepático, 41 (72%) eran mujeres y 32 (56%) tenían un HHG. La mediana de tamaño fue de 4.49cm. Con respecto a los HHG, el 31.2% estaban asintomáticos; el síntoma más común fue dolor. Tanto los síntomas como el uso de anticonceptivos orales fueron más comunes en pacientes con HHG. Nueve pacientes con HHC fueron sometidos a cirugía: 2 biopsias abiertas por duda diagnóstica, una enucleación y 6 resecciones.
Los HHG son más prevalentes en mujeres y, cuando son sintomáticos, el dolor es la manifestación más frecuente. El diagnóstico habitualmente se hace por imagen, pero a ve |
