9y MC Toy Poodle with a 3‐week history of seizures. A large, T1 hypointense, T2 and FLAIR hyperintense ovoid mass is seen in the ventral
aspect of the left frontal lobe (a–c: arrow). There is mild enhancement in part of the mass following contrast administration (d,e: arrow).
A more rostral contrast‐enhanced CT image reveals a hypoattenuating mass effect in the left frontal lobe inducing midline shift (f: arrow).
Biopsy revealed the mass to be a grade II astrocytoma.
