Adrenal haemangioma

Case contributed by A.Prof Frank Gaillard

Presentation

History of urothelial carcinoma.

Patient Data

Age: 75 years
Gender: Male
CT

The left adrenal gland demonstrates a soft tissue mass (27HU on non-contrast phase) which demonstrates prominent arterial enhancement peripherally and gradually fills in. It remains a similar attenuation to the aorta on all sequences including delayed scans. 

Incidental note is made of a simple (grade 1) renal cyst on the left. 

Conclusion:

The features indeterminate and a malignant lesion (e.g. adrenal metastasis or adrenal carcinoma) cannot be excluded. 

Case Discussion

The patient, therefore, went on to have a resection. 

Histology

Macroscopic description

This is an adrenal gland weighing 29 grams,  covered in fatty tissue measuring  75 x 40 x 25mm.  The adrenal gland is serially sliced to reveal within the gland parenchyma a is reddish black tumour mass,  measuring 18 x 14 x  24mm in maximum dimension. Most of the mass is surrounded by a rim of adrenal parenchyma. 

Microscopic description

Sections of adrenal gland show a  circumscribed but a non-encapsulated tumour within adrenal gland, involving cortex and medulla.  There are irregularly shaped anastomosing vascular channels present,  separated by variably abundant hyalinised collagenous stroma.   The vessels are lined by endothelial cells with small nuclei with only mild pleomorphism,  and mitotic figures are not identified.  In areas, there are larger vessels containing organizing blood and fibrin clot.   The features are most in keeping with a haemangioma.  Focally,  the lesion is disrupted; however, in intact regions, the lesion is clear of margins.  The adjacent adrenal gland is unremarkable.  There is no evidence of metastatic carcinoma.

FINAL DIAGNOSIS: adrenal haemangioma. No metastatic carcinoma identified.
