    Acromesomelic-Spondyloepiphyseal Dysplasia Associated With Congenital Optic Atrophy - Report of a Family
    (Springer Verlag, 1993) Sener, Rn; Ustun, Ee; Özkınay, Cihangir; Memis, A; Oyar, O
    We report a family with a unique combination of radiological manifestations of acromesomelic dysplasia and spondyloepiphyseal dysplasia in two members (a man and his daughter) associated with congenital optic atrophy in four generations. The inheritance pattern of this complex anomaly appeared to be autosomal dominant.

    Acute Epidural Hematoma With Hypodense Bubbles on Ct - a Sign of Dural Sinus Tear Or Solely Fresh Bleeding
    (Springer Verlag, 1993) Sener, Rn
    Acute epidural haematomas are less commonly seen in children than in adults, and are even rarer in infants. On CT these haematomas sometimes show hypodense bubbles, an appearance the interpretation of which has been a matter of controversy. Identification of the origin of the bleeding - whether from torn dural sinuses or transected meningeal vessels - is neurosurgically significant. This report presents the CT study of an infant with an acute epidural haematoma containing hypodense bubbles which OCCurred due to fresh bleeding from injured meningeal vessels.

    Anterior Callosal Agenesis In Mild, Lobar Holoprosencephaly
    (Springer Verlag, 1995) Sener, Rn
    The corpus callosum normally grows in a ventral to dorsal direction with the genu appearing first followed by posterior growth to form the body and splenium. In holoprosencephaly there usually is a malformation of the lamina terminalis which results in lack of formation of the corpus callosum. This paper presents a patient with mild, lobar holoprosencephaly in whom a different type of callosal dysgenesis was detected: the callosal body and splenium were apparently formed but the anterior parts were absent. The existence of this type of callosal dysgenesis appears to be in contrast to current theories on callosal development.

    Bilateral Large Bochdalek Hernias In An Adult - Ct Demonstration
    (Elsevier Science Publ Co Inc, 1995) Sener, Rn; Tugran, C; Yorulmaz, I; Dagdeviren, A; Orguc, S
    Bochdalek hernia is a congenital posterior diaphragmatic defect resulting from failure of the retroperitoneal canal membrane to fuse with the dorsal esophageal mesentery and the body wall. A recent computed tomography study indicated that these defects frequently can be identified on routine chest and abdominal images, and classified them as small, medium, and large, the large ones being identifiable on five or more contiguous axial scans consisting of 1-cm-thick sections. Although the overall prevalence of Bochdalek hernias is 6%, and that of bilateral hernias is 0.9%, to date only a few patients with unilateral or bilateral large hernias have been reported. This article describes an adult with asymptomatic, bilateral, large Bochdalek defects containing herniated retroperitoneal fat.

    The Claustrum on Mri - Normal Anatomy, and the Bright Claustrum As a New Sign In Wilsons-Disease
    (Springer Verlag, 1993) Sener, Rn
    One hundred MRI examinations of normal subjects obtained at 0.5 T were studied in an effort to evaluate the claustrum and to establish a control group for patients with Wilson's disease. The claustrum was detectable unilaterally or bilaterally in 40 out of 100 subjects (40%) on spin-echo long TR (proton density and T2-weighted) MR images as a thin sheet of grey matter enclosed by low signal white matter of the external and extreme capsules. Spin-echo T1-weighted images were negative for the claustrum, however, it was identifiable in 12 out of 25 subjects (48%) studied utilizing the inversion recovery pulse sequence. In addition, eight patients with clinically established diagnoses of Wilson's disease were evaluated. The claustrum was normal (invisible) in four neurologically asymptomatic Wilson's disease patients, however, in 75% (n = 3) of the four neurologically symptomatic patients it was bilaterally thickened and bright on long-TR MR images. The bright claustrum appears to be a new sign in Wilson's disease.

    Ct of Diffuse Leptomeningeal Metastasis From Primary Extracerebral Neuroblastoma
    (Springer Verlag, 1993) Sener, Rn
    Leptomeningeal metastasis due to primary extracerebral neuroblastoma is rare. Diffuse leptomeningeal contrast enhancement resulting from this condition has been demonstrated only in a recent case report utilizing cranial CT imaging. The case presented here is the second example of diffuse leptomeningeal metastasis from primary extracerebral neuroblastoma. Metastasis was visualized by pre- and postcontrast cranial CT scans 6 months after the diagnosis of the disease when the patient had developed multiple cranial nerve palsies.

    Ct of Gyriform Calcification In Tuberous Sclerosis
    (Springer Verlag, 1992) Sener, Rn; Meral, A; Farmaka, H; Kalender, N
    This paper presents a patient with typical clinical and CT features of tuberous sclerosis associated with gyriform calcification of the most part of the left frontal lobe. This patient represents the third case of tuberous sclerosis in the literature presenting with gyriform calcification.

    Cysts of the Septum Pellucidum
    (Pergamon-Elsevier Science Ltd, 1995) Sener, Rn
    A septum pellucidum cyst is defined as a cystic structure between the lateral ventricles, whose walls exhibit lateral bowing and are 10 mm apart or greater, This communication presents computerized tomography (CT) and magnetic resonance imaging (MRI) findings in six patients with septum pellucidum cysts, ages ranging from 1.5 to 47 yrs, The width of the cysts ranged from 13 to 23 mm, and their walls were laterally bowed. Only one patient had hydrocephalus, who was surgically treated. The remaining five patients only had intermittent headaches. It appears that further studies will be required to establish satisfactory diagnostic and therapeutic criteria for symptomatic or presumably symptomatic septum pellucidum cysts.

    Growing Skull Fracture In a Patient With Cerebral Hemiatrophy
    (Springer Verlag, 1995) Sener, Rn
    A growing skull fracture or leptomeningeal cyst most commonly occurs in children under the age of 3 years, and is extremely rare in adults. The reason for a growing skull fracture is usually a dural tear in association with the fracture. This paper presents an 18-year-old mentally retarded patient with cerebral hemiatrophy (Dyke-Davidoff-Masson syndrome) associated with a growing skull fracture in the ipsilateral hemicranium, in whom not only a dural tear but also the ipsilaterally displaced and dilated lateral ventricle due to the original disease apparently contributed to the development of growing skull fracture.

    Gyral Calcifications Detected on the 45Th Day After Cerebral Infarction
    (Springer Verlag, 1993) Sener, Rn
    The case is presented of a child with cyanotic congenital heart disease in whom middle cerebral artery stroke occurred, and consequently heavy gyriform calcification developed in the infarcted area within 45 days. To the author's knowledge, this is the shortest time interval within which such a calcification has ever been demonstrated.
