    Notes: Abstract Contrast medium was given intravenously to three nonalcoholic patients who underwent MRI or CT in the acute stage of Wernicke's encephalopathy. Pathological enhancement was not seen in one patient examined within 4 days of clinical onset, was mild in a another 3 days after clinical deterioration and marked in a patient examined 12 days after admission. Contrast enhancement of lesions was present in half of 12 cases of acute disease reported previously. There was a substantial overlap in the time interval between clinical onset and contrast-enhanced CT or MRI in the groups of enhancing and nonenhancing lesions. Since contrast enhancement may be absent in acute WE, proton-density and T 2-weighted images are more useful for diagnosis of this reversible but potentially fatal condition.

    Notes: Abstract  Orbital cavernous hemangiomas (OCH) have thick and highly cellular vascular walls. Ultrastructural studies have demonstrated the smooth muscle nature of these cells. Vascular neoplasms can modify their morphological and clinical features under hormonal stimulation. The purpose of the present study was to investigate the presence of smooth muscle markers and sex steroid receptors in 12 cases of OCH. Orbital cases were compared with cutaneous hemangiomas and subcutaneous angioleiomyomas. Smooth muscle actin (SMA) and desmin were localized in spindle cells of the vascular walls of all 12 cases studied. OCH showed immunohistochemical positivity with progesterone receptor (PR) antibody both in smooth muscular and in endothelial cells. For comparison, sex steroid receptors were studied in 10 cases of cutaneous cavernous hemangioma and in 10 cases of subcutaneous angioleiomyoma. PR was found in smooth muscle and endothelial cells of 6 out of 10 cases of subcutaneous angioleiomyoma and in none of the cases of cutaneous cavernous hemangioma. No positivity was obtained with estrogen receptor (ER) antibody in any of the cases tested. The present data suggest that OCH share morphological and immunohistochemical features with subcutaneous angioleiomyomas. Furthermore, immunohistochemical positivity with PR antibody indicates that OCH have to be added to the list of mesenchymal lesions that express sex steroid receptors.

    Gaze-evoked amaurosis heralding orbital angiomyoma. Case report (1997)

    Description / Table of Contents: Sommario È descritto il caso atipico di una paziente che presentò un'amaurosi da sguardo come segno isolato precoce di un angiomioma orbitario. La tomografia computerizzata o la risonanza magnetica devono essere rapidamente eseguite in pazienti con amaurosi da sguardo in modo da identificare o escludere un possibile sottostante tumore orbitario.
    Notes: Abstract The unusual case of a patient presenting with gaze-evoked amaurosis as an early and isolated sign of orbital angiomyoma is reported. Computed tomography or magnetic resonance of the orbits need to be expeditiously performed in patients with gaze-evoked amaurosis in order to identify or rule out the possible presence of an underlying tumor.
