Le Nestour E, Abécassis J-P, Bertagna X, Bonnin A, Luton J-P. Silent necrosis of a pituitary corticotroph adenoma revealed by timely magnetic resonance imaging: a cause of spontaneous remission of Cushing's disease. Eur J Endocrinol 1994;130:469–71. ISSN 0804–4643 Spontaneous necrosis of a corticotroph adenoma is rare and is a very unlikely way of curing Cushing's disease. We report hereafter a case where magnetic resonance imaging of the pituitary provided clear evidence of the event. Successive and timely pituitary magnetic resonance imaging in this patient showed first a typical microadenoma as a well-limited mass with a low signal intensity before the necrosis, then a bright signal before gadolinium injection in the T1-weighted image at the time of the event and, finally, the aspect of an empty sella turcica with a small arachnoidocele 1 year later. The necrosis of a corticotroph adenoma is more frequent in macro- than in microadenomas, and is usually heralded by headache and visual disturbances. In this case, pituitary necrosis was entirely asymptomatic, and cured the patient as well as the surgeon's knife would have. Nevertheless, this exceptional occurrence does not rule out the possibility of a recurrence.

The purpose of this study is to identify salient magnetic resonance imaging (MRI) findings of pediatric IIH, to determine the relevance of these findings with regard to disease pathogenesis, and to relate these findings to the clinical presentation towards identification of risk factors of disease. A retrospective, a case–control study of 38 pediatric patients with and 24 pediatric patients without IIH from the ophthalmology department at a tertiary care center was performed. Clinical data, including ophthalmic findings and lumbar puncture results, were recorded. Neuroimaging, including both MRI and magnetic resonance venography (MRV), was evaluated for perioptic subarachnoid space diameter enlargement, posterior globe flattening, optic nerve head protrusion, empty or partially empty sella turcica, dural venous sinus abnormalities, skull base crowding, and prominent arachnoid granulations. Compared with controls, IIH patients had larger perioptic subarachnoid space diameters, higher incidences of posterior globe flattening, protrusion of the optic nerve heads, an empty sella turcica, and dural venous sinus abnormalities. A perioptic subarachnoid space diameter of ≥5.2 mm was identified as an independent predictor of IIH (p < 0.001) with sensitivity of 87% and specificity of 67%. Several significant MRI findings in pediatric IIH were identified. Using a model that uniquely incorporated clinical and MRI findings at presentation, we provide a framework for risk stratification for the diagnosis of pediatric IIH which may be utilized to facilitate diagnosis. Future prospective work is needed to further validate the model developed in this study.

Glomus tumor is one of the most common temporal bone tumors. Most of them are benign and locally invasive, some are occasionally able to metastasize and have signs of malignancy. Diagnostic imaging is necessary before treatment. Computer tomography (CT) is traditionally used as a primary method of diagnosis, to recognize changes in the temporal bone. Role of magnetic resonance imaging (MRI) in temporal bone tumor diagnosis is not definitively determined.Purpose. To assess the possibilities of computer and magnetic resonance tomography, to develop an algorithm for the application of diagnostic imaging methods in the diagnosis of glomus tumors of the temporal bone.Material and methods. The article presents the experience of diagnosing 30 patients with glomus tumors.Results. The tympanic form of the glomus tumor was observed in 11 cases (37%), tympano-yugular in 19 cases (63%). CT and MRI data totally coincided in cases of small tumors (type A and B). In the presence of extended forms CT ability of assessing bone invasion, involvement of the internal carotid artery, internal jugular vein, and dural sinuses was lower than the MRI.

The analysis of the diagnostic informativeness of modern radiodiagnosticis methods in determining metastatic lymph node of pelvic cancer gynecological organs according to domestic and foreign publications. At the present stage methods of obtaining visual images pelvic lymph nodes are radiodiagnostics technologies (radiological, ultrasound, magnetic resonance tomography, scintigraphic). The analysis has shown that the researches devoted to diagnostic informational content of modern methods of radiodiagnosis in a differentiation of nature of damage of pelvic lymph nodes aren't enough. According to the literature, the most rational and perspective method for radiodiagnosis metastatics lymph node is a magnetic resonance imaging due to the high information content and thus specificity. At the same time, the continued relevance of further study of methods of radiodiagnostics in order to find the optimal one for the assessment of pelvic lymph nodes.

ABSTRACT Twelve patients (10 women and 2 men) with a primary empty sella turcica were studied. Endocrine function tests were performed as follows: growth hormone (GH) was measured after insulin-induced-hypoglycaemia, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) after LH-releasing hormone, thyrotrophin (TSH) and prolactin after thyrotrophin-releasing hormone; pituitary reserve of adrenocorticotrophin (ACTH) was determined by measurement of plasma cortisol after lysinevasopressin and 11 deoxycortisol after metyrapone. Five of the patients (group A) had no endocrine disturbance. Seven patients (group B) had a hypothalamo-pituitary disorder. Two of them had panhypopituitarism which appeared in one case after meningoencephalitis and in the other after a severe cranial trauma. In two cases an amenorrhoea-galactorrhoea syndrome with increased prolactin level (68 and 230 ng/ml) led to a diagnosis of a prolactin producing adenoma, which was confirmed by surgery. Finally three cases of amenorrhoeagalactorrhoea, with normal prolactin level, and/or diabetes insipidus remained unexplained. However, no causal relationship could be demonstrated between the pituitary disturbance and the "empty sella". Primary empty sella turcica is therefore a neuroanatomical and neuroradiological entity with no endocrine implication. A pituitary disorder might suggest a microadenoma or an incidentally associated disease.
