Pituicitoma es un tumor único de bajo grado, originado en las células magnocelulares de la neurohipófisis, o en el infundíbulo. Es una entidad rara, que afecta a los adultos. Las manifestaciones clínicas dependen de la localización y el tamaño, pudiendo simular un adenoma hipofisiario, pues también puede comprometer cualquier eje hipofisiario. El diagnóstico se realiza por medio de resonancia magnética nuclear (RMN) y biopsia, y su tratamiento puede ser por medio de medicamentos o cirugía.En este articulo presentamos dos casos clínicos de dos adultos con pituicitoma, quienes tuvieron hallazgos radiológicos similares.Abstract Pituicytoma is an only low-grade tumor which is originated from magnocellular cells in neurohypophysis or in infundibulum. It is a rare condition that affects adults. The clinical manifestations depends on the location and size because it is similar to a pituitary adenoma, so it produces nonspecific damage to the pituitary axis. For the diagnosis is usually performed with Magnetic Resonance Imaging (MRI) and biopsy and treatment of this disease may be with drugs or surgery.In this article we show two clinical cases of two adults with pituicytoma who had similar radiological findings.

Heart sarcoidosis diagnosis presents great difficulties due to the absence of specific clinical manifestations. Most often, the diagnosis is established during autopsy. Magnetic resonance imaging (MRI) of the heart with contrast enhancement is one of the most informative methods of intravital diagnosis of cardiac sarcoidosis. In this article, two clinical cases, shows the role of MRI of the heart with contrast enhancement in the diagnosis of cardiac sarcoidosis.

This article reports the case of a 68-year-old patient with anti-HU antibodies paraneoplastic encephalitis. The clinical manifestations were atypical and the paraclinical work-up, notably the magnetic resonance imaging (MRI) showing bilateral posterior thalamic hyperintensities (pulvinar sign), misleadingly pointed towards a variant Creutzfeld–Jakob disease. After presenting the case, the differential diagnosis of the pulvinar sign is discussed along with other important diagnostic considerations.

Pituitary apoplexy is a rare condition which may cause death of the patient in severe cases and many times leads to hypopituitarism. We report a case of apoplexy in a large prolactinoma resulting in empty sella syndrome followed by a successful pregnancy. Our patient is a 32-year-old female with a history of a macroprolactinoma for approximately 17 years who presented to our hospital with a history of severe headache, decreased level of consciousness, fever, nausea, vomiting, and diplopia of 12 hours duration. Magnetic resonance imaging done on admission showed an increase in the size of the pituitary adenoma with a subtle hemorrhage. The patient was admitted to the intensive care unit and treated conservatively. The condition of the patient improved within a few days. A few months later, she started having regular menstrual periods. A magnetic resonance imaging of the pituitary 1.5 years later was reported as empty sella syndrome, and approximately one year later she became pregnant. With the pituitary adenoma being resolved after developing pituitary apoplexy and continuing on cabergoline, the patient had a successful pregnancy with no recurrence of the adenoma after delivery and breastfeeding.

Objective: To investigate resting state (RS) functional connectivity (FC) abnormalities within the principal brain networks in a large cohort of multiple sclerosis (MS) patients, to define the trajectory of FC changes over disease stages and their relation with clinical and structural magnetic resonance imaging (MRI) measures. Methods: RS functional magnetic resonance imaging (fMRI), clinical, and neuropsychological evaluation were obtained from 215 MS patients and 98 healthy controls. Connectivity abnormalities and correlations with clinical/neuropsychological/imaging measures were evaluated. We analyzed seed-voxel FC with seven major hubs, producing one visual/sensory, one motor, two cognitive, one cerebellar, and two subcortical networks. Results: MS patients showed reduced network average RS FC versus controls in the default-mode network. At regional level, a complex pattern of decreased and increased RS FC was found. Reduced RS FC mainly involved sensorimotor, cognitive, thalamic, and cerebellar networks, whereas increased RS FC involved visual/sensory and subcortical networks. Reduced RS FC correlated with T2 lesions. Reduced thalamic RS FC correlated with better neuropsychological performance, whereas for all remaining networks reduced FC correlated with more severe clinical/cognitive impairment. Conclusion: Increased and decreased RS FC occurs in MS and contributes to a wide spectrum of clinical manifestations. RS FC reduction is related to T2 lesions. Such a paradigm is inverted for the thalamic network.

In this article we would like to discuss the issues of adrenal pathology and its diagnostics. This is a complex review according to modern sources, fundamental knowledge and author’s experience. All clinical cases are original and morphologically verified. There are different types of classifications with different features, showed in this article. The most useful diagnostic methods are computed tomography (CT) and magnetic resonance imaging (MRI) with special contrast enhancement protocols, described in article.

Background. Congenital absence of the submandibular gland (SMG) is a rare condition. Although complaints such as dry mouth, dental problems, or difficulty in swallowing may be seen, the subjects may also be asymptomatic. The absence of the SMG may be associated with hypertrophy of the contralateral SMG.Case Report. We report the case of a 44-year-old woman with incidentally detected left SMG aplasia, with contralateral SMG hypertrophy mimicking a mass, and the case of a 46-year-old woman with incidentally detected bilateral SMG aplasia, demonstrated by computerized tomography (CT) and magnetic resonance imaging (MRI).Conclusion. It is important for the clinician to know that this very rare abnormality may exist. When such a case is encountered, symptoms and findings should be reevaluated and, if necessary, conservative therapy should be initiated. The possibility of observing additional deformities should be kept in mind and an evaluation should be done for other cases in the family.

Hypothermia is a rare condition in multiple sclerosis (MS). We report on a patient with a longstanding secondary progressive MS and six episodes of recurring hypothermia down to 29.98C with associated hypotension, bradycardia, coagulopathy and electrolyte dysequilibrium. Magnetic resonance imaging (MRI) demonstrated severe involvement of the corpus callosum with an associated lesion in the right posterior thalamus. These findings may link hypothermia in MS with callosal and associated thalamic pathology to Shapiro’s syndrome, where agenesis of the corpus callosum and associated abnormalities are related to episodic spontaneous hypothermia. In MS, hypothermic episodes may be triggered by preceding infections, as shown in the present case.

ABSTRACT Creutzfeldt-Jacob disease (CJD) is a rare condition caused by a pathogenic prion protein that evolves with rapidly progressive dementia and death. The clinical presentation may sometimes be misleading. Magnetic Resonance Imaging (MRI) aids diagnosis with patterns that can guide or confirm clinical hypotheses. Two cases of rapidly progressive dementia with ataxia, myoclonus and restricted diffusion on MRI in cortical/basal ganglia are presented to draw attention to CJD.
