Neurilemmoma showing a unique growth pattern in the lateral chest wall: both inside and outside the thoracic cavity.

Abstract

We report the first case of the intercostal neurilemmoma showing a unique growth

pattern in the lateral chest wall (both inside and outside the thoracic cavity).

Usually, intrathoracic neurilemmoma is found in the posterior mediastinum and

bulge from the inner surface of the bony thorax toward the thoracic cavity. This

unique growing pattern of neurilemmoma arising from intercostal nerve was clearly

demonstrated by computed tomography and ultrasonography.
