Plain-English summary
An 8-year-old German wirehaired pointer and a 3-year-old German shepherd were both found to have firm, painless lumps in their muscles. MRI scans showed signs that these lumps could be cancerous, but tests confirmed they were low-grade fibrosarcomas, which are tumors that can behave aggressively despite their low-grade classification. The detailed imaging helped the veterinarians plan for biopsies and surgery. Both dogs received appropriate treatment based on these findings, which is crucial for managing their conditions.

Abstract
Two adult neutered male dogs were presented for evaluation of firm, painless masses arising within muscle: an 8-year-old German wirehaired pointer dog with an accessory tricipital growth, and a 3-year-old German shepherd dog with a gracilis muscle growth. Magnetic resonance imaging (MRI) characteristics suggested malignant behavior, with a central fluid-like portion with a hyperenhancing lining, a nidus of disorganized tissue, and an extensive reactive zone, whereas histopathology was consistent with low-grade fibrosarcoma. This report describes histologically low-grade, yet biologically high-grade intramuscular fibrosarcoma, in which MRI provided detailed information on tumor behavior and assisted with biopsy and surgical planning.
