Dorsal Root Ganglion Size in Patients With Complex Regional Pain Syndrome of the Lower Extremity: A Retrospective Pilot Study.

Objective: Complex regional pain syndrome (CRPS) is a debilitating chronic condition characterized by severe, nociplastic pain along with various other symptoms. Neuromodulation, particularly electrical stimulation of the dorsal root ganglion (DRG), has emerged as a promising intervention for patients with CRPS unresponsive to conventional treatments. However, little is known about the anatomical characteristics of DRGs in patients with CRPS.

Skull Base-related Lesions at Routine Head CT from the Emergency Department: Pearls, Pitfalls, and Lessons Learned.

Routine non-contrast material-enhanced head CT is one of the most frequently ordered studies in the emergency department. Skull base-related pathologic entities, often depicted on the first or last images of a routine head CT study, can be easily overlooked in the emergency setting if not incorporated in the interpreting radiologist's search pattern, as the findings can be incompletely imaged. Delayed diagnosis, misdiagnosis, or lack of recognition of skull base pathologic entities can negatively impact patient care.

Root Cause Analysis: An Examination of Odontogenic Origins of Acute Maxillary Sinusitis in Both Immunocompetent & Immunocompromised Patients.

Background And Purpose: Dental and periodontal diseases represent important but often overlooked causes of acute sinusitis. Our goal was to examine the prevalence of potential odontogenic sources of acute maxillary sinusitis according to immune status and their associations with sinusitis.

Materials And Methods: A retrospective review of maxillofacial computed tomography studies from 2013 to 2014 was performed.

Curtains.

A 55-year-old immunocompetent man presented with headache, nausea, progressive bilateral upper lid ptosis, and diplopia. Examination showed bilateral asymmetric upper lid ptosis with limited adduction and elevation of both eyes. Cranial magnetic resonance imaging revealed enhancing intra-axial and extra-axial midbrain lesions.

Cerebellopontine angle tumor in a patient with a maternally inherited SDHD gene mutation.

Acoustic neuromas are the most common tumor in the cerebellopontine angle (CPA) but are rare in the general population. Paragangliomas are rarer still and, in a minority of cases (20%), are known to be caused by errors in the SDHD gene. Mutations in this gene are highly penetrant when inherited paternally but not maternally.

Multiple myeloma invasion of the central nervous system.

Background: Although neurologic manifestations often complicate the course of patients with multiple myeloma (MM), direct central nervous system invasion is rare.

Objective: To describe the neurologic symptoms and signs, imaging, cerebrospinal fluid findings, and the clinical course of patients with central nervous system myeloma invasion, all of whom had leptomeningeal myelomatosis.

Design And Participants: Review of 23 patients with MM and leptomeningeal myelomatosis proven by malignant plasma cells in their cerebrospinal fluid.
