Ectopic thymus results frown the aberrant migration of thymic tissue and is mostly
present in the mediastinum, the base of the skull, the tracheal bifurcation and the
cervical region. We report the first case of intraabdominal heterotopic thymus
incidentally detected and attached to the liver without associated anomalies. This fetus
was sent to the Department without any clinical information. The fetus was small for
gestational age, but had no external abnormalities. Each organ shoved normal
development except for the liver. The liver weighed 6 gm(normal 17.064¡¾4.143 gm).
Gray white heterotopic thymus was attached to the superior surface of the liver in the
subdiaphragmatic area. It measured 1.1¡¿0.6¡¿0.5 §¯. There was no diaphragmatic defect.
The cervical thymic tissue near the thyroid was small and measured 0.2 gm(normal
0.927¡¾0.485gm). There was no thymic tissue in the anterior superior mediastinum. The
histologic features of the heterotopic thymus were identical to the orthotopic thymus
showing features appropriate for the gestational age. The origin of this subdiaphragmatic
heterotopic thymus is speculated.
