Infants (n\u00a0=\u00a044) presented with benign cysts (42\/44, 95%, one bilateral), a benign neoplasm (1\/44, 2%) and a torsion without other pathology (1\/44, 2%).

Most infants were symptomless. Lesions in 1\u2010 to 11\u2010year\u2010old girls (n\u00a0=\u00a034) included benign neoplasms (n\u00a0=\u00a021\/34, 62%), malignant neoplasms (n\u00a0=\u00a05\/34, 15%), a cyst with torsion (n\u00a0=\u00a01\/34, 3%) and torsions without other pathology (n\u00a0=\u00a07\/34, 21%).
