Plain-English summary
An 11-year-old spayed female American Staffordshire Terrier was brought in for an Addisonian crisis, which is a serious condition caused by insufficient hormone production from the adrenal glands. An abdominal CT scan showed a mass on the right adrenal gland that was affecting the vena cava, a major vein. The dog was treated for the crisis, but the owners chose not to pursue further treatment for the mass. A year later, a follow-up scan revealed that the mass had resolved, although both adrenal glands had become smaller.

Abstract
An 11-year-old spayed female American Staffordshire Terrier was evaluated for an Addisonian crisis. Abdominal CT scan revealed a mass-like lesion arising from the right adrenal gland and invading into the vena cava. The patient was treated for an Addisonian crisis, and no further treatment for the right adrenal gland mass was pursued by the clients. The patient presented 1 year later for re-evaluation of the right adrenal gland mass, and an abdominal CT scan was performed, which showed the previous right adrenal gland mass had resolved, and both adrenal glands were now atrophied. Adrenal hemorrhage can occur following an Addisonian crisis, and this is the first case report with imaging studies documenting this phenomenon.
