A 16-year-old MN DSH cat was presented for evaluation of acute vision loss and was diagnosed with hypertension, retinal detachment, hypokalemia, urinary tract infection, and an intermittent arrhythmia.
Case Study
Enlarged, irregular, mineralizing adrenal, suspect Conn’s Syndrome in a 16 year old MN DSH cat
Sonographic Differential Diagnosis
Enlarged, irregular mineralizing right adrenal gland.
This is strongly suggestive for adenocarcinoma and Conn’s syndrome given the hypokalemia. Functional aldosterone producing tumor is suspected. There was no evidence of vascular invasion or metastatic disease. This appears to be resectable. I recommend surgical consultation or right adrenalectomy after hypertension has been treated. Aldosterone levels should be measured.
Image Interpretation
The right adrenal gland in this patient was enlarged, irregular and focally mineralizing. The left adrenal gland was uniform with no evident pathology and measured 0.5 cm.
DX
Enlarged, irregular, mineralizing adrenal
Outcome
This is strongly suggestive for adenocarcinoma and Conn’s syndrome given the hypokalemia. Functional aldosterone producing tumor is suspected. There was no evidence of vascular invasion or metastatic disease. This appears to be resectable. Surgical consultation or right adrenalectomy is recommended after hypertension has been treated. Aldosterone levels should be measured.
Clinical Differential Diagnosis
Idiopathic hypertension, Conn’s syndrome (adrenal hyperplasia, adrenal neoplasia), renal disease
Bacterial cystitis
