"Hepatic mesenchymal hamartomas typically occur in children and neonates 3 with most cases presenting within the first two years of life 3. They rarely present in adults 10. There is a reported male predominance of 2:1 13."
"Mesenchymal hamartomas are benign lesions and are best treated by surgical resection, which usually results in cure 2. There are occasional reports of ultrasound-guided intraoperative aspiration of fluid from the cystic components of the tumour to reduce its volume, facilitating surgical resection 5."
"There are fatal complications associated with hepatic mesenchymal hamartomas (particularly in the prenatal group) that generally result from the size of lesion 2:"
"On a cut surface, there are typically multiple cysts in an oedematous stroma; the cysts can vary in size, ranging from a few millimetres to 16 cm, and in number and distribution, being discrete or connected 13."
