A case of porencephaly complicated by central diabetes insipidus in a dog

Abstract

Porencephaly is an extremely rare congenital disorder of the central nervous system characterized by focal cerebral cysts and cavities. Central diabetes insipidus is also a well-described condition in veterinary medicine. A 4-year-old Terrier dog was referred to the hospital with polyuria and polydipsia. Based on a diagnostic examination, porencephaly complicated by central diabetes insipidus was determined. Treatment consisted in administering intranasal desmopressin to the conjunctiva. The dog remains clinically healthy for 2 years. This case report reflects the MRI features of porencephaly and central diabetes insipidus associated with congenital porencephaly.
