Cardiovascular Manifestations of Erdheim-Chester's Disease: A Case Series.

Arq Bras Cardiol 2018 Dec;111(6):852-855

Instituto do Câncer do Estado de São Paulo, São Paulo, SP - Brazil.

Erdheim-Chester Disease is a rare entity, classified as an inflammatory myeloid neoplasm, with an unknown incidence, occurring preferentially in men after 50 years of age. Classically, it has a multisystemic presentation, with the skeletal system being the most frequently affected (90% of the patients), followed by genitourinary involvement in 60% of cases and central nervous system in the pituitary and diabetes insipidus in 25% of the cases. Cardiovascular manifestations are present in more than half of the patients, with aortic infiltration and atrial pseudotumor being the most common forms. Read More

Cytomegalovirus (CMV) is the most common cause of severe opportunistic viral disease among patients with acquired immunodeficiency syndrome, and colitis is the most frequent manifestation of CMV infection. Nevertheless, the development of a colonic pseudotumor is a rare benign entity that can be easily misdiagnosed as a colonic neoplasm if the radiologist is not aware of this condition. We present a case of a 42-year-old male with a CMV pseudotumor of the colon. Read More

Department of Imaging and Medical Information Sciences, Division of Radiology, Geneva University Hospitals, Geneva, Switzerland.

Retroodontoid pseudotumor (ROP) is a nonneoplasic lesion of unknown etiology, commonly associated with inflammatory conditions, and the term of pannus is usually used. Less frequently, ROP formation can develop with other noninflammatory entities, with atlantoaxial instability as most accepted pathophysiological mechanism for posttraumatic or degenerative ROP. As it can clinically and radiologically mimic a malignant tumor, it is paramount for the radiologist to know this entity. Read More

Immunoglobulin G4 (IgG4)-related disease can affect the cardiovascular system, including the coronary arteries and pericardium and especially the walls of large and medium-sized vessels. The presence of coronary involvement is critical, as this condition can cause myocardial ischemia or sudden cardiac death. Although histopathologic examination remains the reference standard for detecting organ involvement and diagnosing IgG4-related disease, obtaining biopsy or surgical specimens from the vessel wall is still challenging.

Many studies report the adverse responses to metal-on-metal (MoM) hip prostheses, with tissues surrounding failed MoM hip prostheses revealing abundant tissue necrosis and fibrosis. These local effects appear to be initiated by metal ions released from the prosthesis causing the secretion of inflammatory mediators. However, little is known about the effect of the metal ions on tissue remodelling and pseudotumor formation, which are also associated with the failure of MoM hip prostheses. Read More

The epidural blood patch (EBP) is commonly used to treat postdural puncture headaches (PDPHs) from spinal anesthesia, dural puncture with epidural anesthesia, and diagnostic and therapeutic lumbar puncture. We present a case of a patient with pseudotumor cerebri (idiopathic intracranial hypertension) who had a lumboperitoneal shunt placed for persistent headaches and subsequently developed symptoms similar to a PDPHs that were successfully treated with an EBP. While the exact mechanism by which our patient was experiencing PDPH symptoms is unknown, the EBP administration proved to be both therapeutic and diagnostic by ruling out shunt catheter malfunction through a resolution of symptoms.

The role of lumboperitoneal shunts in managing chronic hydrocephalus with slit ventricles.

J Neurosurg Pediatr 2018 Sep 21:1-6. Epub 2018 Sep 21.

Departments of Neurosurgery and Pediatric Neurosurgery, Wayne State University School of Medicine and Children's Hospital of Michigan, Detroit; and.

Objective: Lumboperitoneal (LP) shunts have a role not only in pseudotumor cerebri, but also in patients with slit-like ventricles who are treated with CSF shunting on a chronic basis. Hesitation to utilize LP shunts is based on previous conventional beliefs including the tendency for overdrainage, difficulties accessing the shunt to tap or revise, and risk of progressive cerebellar tonsillar herniation. The authors hypothesized that the use of horizontal-vertical (HV) valves may reduce the risk of these complications, particularly overdrainage and development of Chiari malformation. Read More

Dural venous sinus stenting for idiopathic intracranial hypertension: An updated review.

J Neuroradiol 2018 Sep 13. Epub 2018 Sep 13.

Department of Neuro Interventional Surgery, Christiana Care Hospital, Newark, Delaware, USA. Electronic address:

Background: Dural venous sinus stenting (DVSS) is an accepted treatment option in selected patients with medically refractory idiopathic intracranial hypertension and obstructive venous outflow physiology prior to cerebrospinal flow diversion (CSFD) surgery. There are no randomized controlled studies focusing on outcomes and complication rates for dural venous sinus stenting.

Purpose: We present the largest comprehensive meta-analysis on DVSS for idiopathic intracranial hypertension (IIH) focusing on success rates, complications, and re-stenting rates to date. Read More
