Plain-English summary
A 9-year-old neutered male miniature schnauzer was brought in because he was drinking a lot of water and urinating frequently. Tests showed he had high calcium levels and a mass in his left anal gland, along with swollen lymph nodes nearby. The mass was surgically removed, and it was diagnosed as anal sac gland adenocarcinoma, which had spread to the lymph nodes. The imaging technique used helped identify the affected areas, and the dog received treatment for his condition.

Abstract
A 9-year-old neutered male miniature schnauzer was referred to our facility with polyuria, polydipsia, persistent hypercalcemia, hypophosphatemia, and elevated parathyroid hormone-related protein. Dual-energy computed tomography (DECT) imaging revealed a mass in the left anal gland (LAG) and enlargement of the left medial iliac lymph node (LML) and the left internal iliac lymph node (LIL). The mass was surgically removed, and the histopathological diagnosis was anal sac gland adenocarcinoma, with metastasis to the LML and LIL. The pathological findings were concordant with those obtained from our evaluation of the spectral Hounsfield unit curve and iodine concentration DECT imaging. DECT analysis may be useful for identifying metastatic lymph nodes.
