Infundibular displacement is a well-known sign following the development of computerized tomography (CT), however, we are unaware of any description of infundibular buckling. Recently, we encountered a 39-year old male, who presented with the clinical picture of acromegaly and a high proclactin level. Growth hormone and somatomedin levels are high. The brain MRI shows a macroadenoma with buckle infundibulum on coronal images (Figure 1). Postoperative MRI shows the surgical changes and the return of the infundibulum to its normal slender configuration (Figure 2). Infundibular displacement to the contralateral or the ipsilateral side of the adenoma is a well-known radiographic sign on both CT scan and MRI. These signs are helpful in diagnosing microadenomas in conjunction with other signs such as focal hypodensity and asymmetrical sella floor.2 However, in most macroadenomas the infundibulum is thick and cannot be differentiated from the adenoma. In our case, the size of the adenoma was slightly bigger than 10mm, which allows differentiating it from the infundibulum. We think that the buckling sign can be a helpful adjunctive sign of pituitary masses. The return of the infundibulum to its normal shape makes the possibility of neoplastic involvement less likely. We conclude that buckling of the pituitary infundibulum can be a helpful adjunctive sign in the diagnosis of pituitary masses  ردمد : 1658-3175  اسم الدورية : المجلة الطبية السعودية  المجلد : 23  العدد : 2  سنة النشر : 1422 هـ 2002 م  نوع المقالة : تعليق  تاريخ الاضافة على الموقع : Monday, March 31, 2008  الباحثون اسم الباحث (عربي) اسم الباحث (انجليزي) نوع الباحث المرتبة العلمية البريد الالكتروني بسام عداس Addas, Bassam باحث رئيسي دكتوراه   محمد جان Jan, Mohammed باحث مشارك دكتوراه   الملفات اسم الملف النوع الوصف  Pituitary_Adenoma.pdf pdf مشاهدة المقالة العلمية كاملة الرجوع إلى صفحة الأبحاث
