The increasing use of radiological examination, especially magnetic resonance imaging (MRI), will probably increase the risk of unintended discovery of bone marrow abnormalities in patients where a hematologic disease would not be expected. In this paper we present four patients with different hematologic malignancies of nonplasma cell types. In all patients the MRI bone marrow abnormalities represent an initial presentation of the disease. These case reports illustrate the importance of a careful diagnostic follow-up without delay of patients with MRI bone marrow abnormalities, because such abnormalities can represent the first sign of both acute promyelocytic leukemia as well as other variants of acute leukemia.

Rare Autosomal Dominant Disease

Birt-Hogg-Dubé syndrome (BHD) is a rare autosomal dominant disease characterized by skin fibrofolliculomas, pulmonary cysts, spontaneous pneumothoraces, and renal cancers. Oncocytomas are benign epithelial tumors that are also rare. Recently, there have been a few case reports of BHD with a parotid oncocytoma that appears to have a BHD phenotype. Here we document the eighth known case and describe the magnetic resonance imaging features of the parotid oncocytoma, which mimicked Warthin’s tumor. Radiologists should be aware of the association between these rare disorders.

Abstract Background Pituitary abscess is a rare condition with nonspecific symptoms that can be delayed. Proper diagnosis needs to occur preoperatively so that the management can be set up accordingly. Accurate diagnosis is challenging because many differential diagnoses can exhibit the same magnetic resonance imaging features. Case presentation We report two cases of pituitary abscess. The first patient was a 66-year-old Arab woman who underwent a surgical procedure for a pituitary macroadenoma and presented 3 months later with chronic headaches and panhypopituitarism. A pituitary abscess was found on the follow-up magnetic resonance imaging. The second patient was a 64-year-old Arab man with no medical history who presented with a chiasmal syndrome with headaches and panhypopituitarism. Brain magnetic resonance imaging showed a heterogeneous pituitary mass that turned out to be a pituitary abscess intraoperatively. These two patients were treated with hormone substitution, endoscopic transsphenoidal drainage, and antibiotherapy, with excellent outcomes. Conclusions Pituitary abscess is a rare and serious condition. Preoperative diagnosis can be challenging because of the many existing differential diagnoses upon imaging. Magnetic resonance imaging is the mainstay technique of imaging due to its multimodal nature. These cases demonstrate the variable patterns of a pituitary abscess seen on magnetic resonance imaging and the potential difficulties in achieving an accurate diagnosis preoperatively due to many other conditions potentially exhibiting the same magnetic resonance imaging features.

Abstract Background Cardiac implantable electronic devices (CIEDs) were long considered a contraindication for magnetic resonance imaging (MRI). Modern devices are now MRI conditional, but still the majority of CIEDs in the population are legacy devices and are classified as unsafe for MRI. There is growing consensus that MRI is also safe in these patients. Purpose The purpose of this study was to perform an up to date systematic review of the evidence evaluating the use of MRI in patients with non-conditional CIEDs. Methods Searches of the PubMed, CINAHL and Embase databases were performed. Studies that assessed the rate of adverse outcomes after MRI in patients with non-conditional CIEDs were included. Studies were excluded if they did not disclose the conditionality of patients CIEDs. Case reports or case series were not included. Results 36 cohort studies were identified. No patient in these studies died during or immediately after MRI. Symptom associated with either torque or heating occurred in <1% of patients. Electrical resets occurred 1–2% of patients. There were no cases of non-conditional lead or generator failure. Inappropriate pacing occurred in <1% of patients. No ICD shocks occurred during MRI. Changes in CIED parameters occurred in 1–4% of patients. Conclusions This systematic review highlights the relative safety of the use of MRI in patients with non-conditional CIEDs. Demonstrated be the fact that no deaths or device shocks have been suffered as a consequence of MRI in any of these studies, and the extremely low incidence of device or lead related complications. Still strict selection and monitoring protocol should be used when imaging these patients. FUNDunding Acknowledgement Type of funding sources: None.

In 5% of cases in the nasopharynx of an adult can be found a neoplasm with benign or malignant nature. Clinical manifestations of such pathology are next: persistent dysfunction of the auditory tubes, nasalness and postnasal drip syndrome. Endoscopy of the nasopharynx, computed tomography of the sinuses and magnetic resonance imaging of the head are the main diagnostic criteria for detecting neoplasms in this area. The tactics of treatment depends on the dysplasia type of the pathological process and varies from endoscopic one-stage resection to chemoradiation treatment. Using the example of two clinical cases, we will consider an algorithm for diagnosis and treatment the patients.
