A 75-year-old woman complained about progressing fatigue. She appeared somnolent, but fully oriented and in no acute distress. Her face was pale and puffy. She did not show any signs of focal neurological disease, and the remainder of the physical examination was unrevealing. Routine laboratory tests were unremarkable except for hyponatremia and mildly decreased levels of free T3 and free T4, with TSH in the normal range. Pituitary function tests demonstrated secondary adrenal insufficiency and hypothyroidism. Magnetic resonance imaging (MRI) unmasked hypophysitis with the characteristic findings of homogeneous gadolinium uptake of the pituitary and a prominent pituitary stalk ('dural tail sign', arrows in Fig. 1 A and B, sagittal and coronal views). Substitution of hydrocortisone and levothyroxine resulted in rapid and sustained improvement of all symptoms and normalisation of laboratory findings. MRI abnormalities normalized within the following six months. At follow-up three years later, MRI signs had further regressed and demonstrated an empty sella (Fig. 2 A and B). 相似文献

We describe the case of a 73-year-old woman with constitutional disorder and pain in the lower limbs, leading to initial suspicion of multiple myeloma. During the diagnostic process, there were discrepancies between the clinical course and findings of complementary tests. After a fulminant clinical course for a few days, the patient died, and a postmortem diagnosis of angioimmunoblastic lymphoma was established. We review the main aspects of this highly infrequent disease, the pathogenesis of which remains uncertain. 相似文献

Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) is a rare form of supraventricular tachycardia. In some patients, the presence of a dual pathway physiology results in two paths in the atrioventricular (AV) node with different conduction velocities. An atrial impulse arriving at the AV node may unfold and travel along these two pathways simultaneously, causing two ventricular activations. Thus, the ventricular rate will be twice the atrial rate. DAVNNT is less common than AVNRT, but its frequency may be underestimated.The ECG is crucial to suspect the diagnosis. At first glance it looks like an irregular tachycardia, but a more careful look shows a rhythmic pattern. A sinus P wave followed by two QRS complexes (narrow or wide) should raise suspicion of this arrhythmia.It is often unnoticed by the patient, and ventricular dysfunction due to tachycardiomyopathy is not uncommon. The response of DAVNNT to medication, including beta-blockers, flecainide, and amiodarone is very poor or absent, so the treatment of choice is slow pathway ablation. We report a Case of cardiomyopathy caused by this entity. 相似文献
