Nerve Entrapments in the Pelvis and Hip.

Semin Musculoskelet Radiol 2022 Apr 24;26(2):153-162. Epub 2022 May 24.

Division of Musculoskeletal Radiology, Department of Radiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.

Clinical symptoms of pelvic entrapment neuropathies are widely variable and frequently nonspecific, thus rendering it difficult to localize and diagnose. Magnetic resonance imaging (MRI), and in particular MR neurography, has become increasingly important in the work-up of entrapment neuropathies involving the pelvic and hip nerves of the lumbosacral plexus. The major sensory and motor peripheral nerves of the pelvis and hip include the sciatic nerve, superior and inferior gluteal nerves, femoral nerve, lateral femoral cutaneous nerve, obturator nerve, and pudendal nerve.

Acute bilateral ureteropelvic junction obstruction as a rare cause of hypertensive crisis: a case report.

J Med Case Rep 2022 May 23;16(1):220. Epub 2022 May 23.

Department of Medicine, Einstein Medical Center Philadelphia, Philadelphia, PA, USA.

Background: Bilateral ureteropelvic junction obstruction is a common cause of secondary hypertension in the pediatric population, often due to congenital malformation. On the other hand, it is less frequently encountered in the adult population and is usually due to an acquired condition, most commonly by a bilaterally obstructing nephrolithiasis causing hydronephrosis and subsequent hypertension. The aim of this study was to investigate and highlight the underlying mechanisms by which acute bilateral ureteropelvic junction obstruction causes hypertensive crisis and why early detection and prompt treatment are necessary to mitigate the effects of elevated blood pressure on target organs.

Institute for Radiology, Kantonsspital Frauenfeld, Switzerland.

The treatment success of catheter-based ovarian vein embolization due to peripheral varicose veins and ovarian vein reflux (OVR) should be investigated in this clinical investagtion. For this study, 95 female patients were identified over a 5-year period (beginning of 2006 to end of 2011) after catheter-based coil (+/- chemical) embolization of the ovarian vein due to peripheral primary or recurrent varicose veins and proven reflux in the ovarian vein. Treatment success was retrospectively assessed in 2014 by means of a structured telephone interview (n=60), clinical examination (n=56), duplex ultrasound (n=56) and magnetic resonance imaging (n=51) in patients who were willing to participate in the study.

Pouch Volvulus - Why Adhesions Are Not Always the Enemy.

Colorectal Dis 2022 May 18. Epub 2022 May 18.

Department of Colon & Rectal Surgery, Cleveland Clinic, Cleveland, OH, USA.

Aim: Minimally invasive approaches to proctocolectomy with ileal pouch anal anastomosis (IPAA) have become standard of care with one benefit being the reduced risk of adhesion-related complications. However, a lack of pouch adherence to the pelvis can lead to increased mobility as well as volvulization, placing pouch viability at risk.

Guidelines to diagnose and treat peri-levator high-5 anal fistulas: Supralevator, suprasphincteric, extrasphincteric, high outersphincteric, and high intrarectal fistulas.

World J Gastroenterol 2022 Apr;28(16):1608-1624

Department of Statistics, Indian Council of Medical Research,New Delhi 110029, India.

Supralevator, suprasphincteric, extrasphincteric, and high intrarectal fistulas (high fistulas in muscle layers of the rectal wall) are well-known high anal fistulas which are considered the most complex and extremely challenging fistulas to manage. Magnetic resonance imaging has brought more clarity to the pathophysiology of these fistulas. Along with these fistulas, a new type of complex fistula in high outersphincteric space, a fistula at the roof of ischiorectal fossa inside the levator ani muscle (RIFIL), has been described.

Malignant pelvic paraganglioma: A case report.

Radiol Case Rep 2022 Jul 6;17(7):2342-2345. Epub 2022 May 6.

Service de Radiologie, CHU HASSAN II de Fès, Fez, Morocco.

Pheochromocytomas arising from outside the adrenal glands are called paragangliomas and constitute a rare disease and can occur in the pelvic retroperitoneum. Symptoms of excess catecholamine production, as well as elevated urine vanillylmandelic acid levels and serum and urine norepinephrine levels, are highly diagnostic for paraganglioma. Imaging can be helpful for the diagnostic of these pelvic tumors, differentiating them from other pelvic masses. Read More
