BACKGROUND: Most @entity1 with @entity1653 ( @entity1653 ) present with visual symptoms mimicking a @entity4611 . Accurate preoperative differentiation is important because @entity1653 requires a craniotomy, whereas the transsphenoidal route is preferred for removal of most pituitary macroadenomas. METHODS: From 1989 to 1994, five @entity1 with @entity1653 were treated at Taichung Veterans General Hospital. All were female, ranging in age from 20 to 60 years. This paper is a retrospective review of clinical features, diagnostic methods, treatment and postoperative visual recovery. RESULTS: The most common symptom, with a duration of one month to two years, was asymmetrical @entity227 . Abnormal endocrine levels were found in one @entity1 (prolactin: 47.91 ng/ml). Another @entity1 was misdiagnosed as having a @entity977 by coronal view computed tomography (CT) and underwent a transsphenoidal operation. Later, an accurate diagnosis was made using magnetic resonance imaging (MRI). She then underwent another operation--unilateral subfrontal craniotomy with @entity5 . The other @entity1 were preoperatively diagnosed as having @entity1653 by MRI. They also underwent unilateral subfrontal craniotomy with @entity5 . All @entity1 showed good visual improvement after their operation. The extent of visual improvement was closely related to the duration of preoperative @entity227 . There was no @entity5 recurrence after a follow-up period of six months to five years (mean, two years and six months). CONCLUSIONS: It should be emphasized that the diagnosis of @entity1653 must first be based on clinical symptoms and signs, or " @entity751 ". It can be accurately diagnosed preoperatively by sagittal view MRI. Early diagnosis will increase the chances of a good postoperative visual outcome.
