A Rare and Challenging Presentation of Empyema Necessitans/Necessitasis Leading to Brachial Plexopathy.

Cureus 2020 May 24;12(5):e8267. Epub 2020 May 24.

Hematology and Oncology, Hamad General Hospital, Doha, QAT.

Empyema necessitasis (EN) also referred to as empyema necessitans (EN) is a rare complication of empyema that can involve soft tissues outside the pleural cavity and can lead to brachial plexus injury. Although, brachial plexus injury most commonly occurs as a result of trauma, inflammation, or malignancies, but it has been rarely seen in EN. We are reporting a rare and challenging case of empyema necessitasis (EN) causing impingement of brachial plexus in a 42-year-old, type 2 diabetic patient, who initially presented to the hospital with left-sided pleuritic chest pain and acute onset of left upper limb weakness.

Post-amputation neuroma of radial nerve in a patient with ephitelioid sarcoma: case report and literature review.

Acta Biomed 2020 03 19;91(1):122-127. Epub 2020 Mar 19.

Radiology Department, National Cancer Institute Pascale Foundation, via M. Semmola 53, I-80131Naples Italy.

Neuroma, also known as traumatic neuroma or amputation neuroma or stump neuroma, is a focal non neoplastic area of proliferative hyperplastic reaction secondary to peripheral nerve damage that commonly occurs after a focal trauma (acute or chronic) or surgery, such as amputation or partial transection. Neuromas are more commonly located in the lower limbs, followed by head and neck; other extremely rare sites include the ulnar nerve followed by the radial nerve and the brachial plexus. A radiologic plan is necessary to recognize soft tissue lesions with a neural origin and whether they are a true tumor or a pseudotumor such as a neuroma, fibrolipoma, or peripheral nerve sheath ganglion.

MR neurography of the brachial plexus in adult and pediatric age groups: evolution, recent advances, and future directions.

Expert Rev Med Devices 2020 Feb;17(2):111-122

Department of Radiology, UT Southwestern Medical Center, Dallas, Texas, USA.

: MR neurography (MRN) of the brachial plexus has emerged in recent years as a safe and accurate modality for the identification of brachial plexopathies in pediatric and adult populations. While clinical differentiation of brachial plexopathy from cervical spine-related radiculopathy or nerve injury has long relied upon nonspecific physical exam and electrodiagnostic testing modalities, MRN now permits detailed interrogation of peripheral nerve anatomy and pathology, as well as assessment of surrounding soft tissues and musculature, thereby facilitating accurate diagnosis. The reader will learn about the current state of brachial plexus MRN, including recent advances and future directions, and gain knowledge about the adult and pediatric brachial plexopathies that can be characterized using these techniques.

Distal Cervical Spondylotic Amyotrophy: Case Reports Demonstrating Clinical/Imaging Segmental Discrepancy.

J Clin Neuromuscul Dis 2019 Dec;21(2):107-111

Division of Neurology, Department of Medicine, The Ottawa Hospital and University of Ottawa, Ottawa, ON, Canada.

Monomelic pure motor amyotrophy may seem to be an ominous syndrome as it leads to consideration of motor neuron disease. We present a series of 3 very similar cases where unilateral pure distal lower motor neuron paresis and atrophy was limited to the C8-T1 myotomes, without long-tract signs. Electrodiagnostic studies were in keeping with a restricted anterior horn cell disorder. Read More

Image-Guided Percutaneous Management of Skull and Spine Giant Cell Tumors: Case Report of 2 Challenging Cases Successfully Treated with Doxycycline Sclerotherapy.

World Neurosurg X 2020 Jan 25;5:100061. Epub 2019 Sep 25.

Department of Radiology, Nationwide Children's Hospital, Columbus, Ohio, USA.

Background: A giant cell tumor (GCT) of bone is a benign, locally aggressive tumor that is often challenging to treat. When complete resection is not possible, curettage with or without adjuvants is the most common treatment. The high frequency of local recurrence and risk of injury to adjacent structures can limit this surgical approach, especially with skull and spine lesions. Read More
