Posterior femoral cutaneous nerve mononeuropathy: A case report

Isolated posterior femoral cutaneous neuropathy following intragluteal injection

“…Only one report has discussed the outcome of PFCN, but the patient was followed up for only 6 months and her symptoms were stable. 1 In our case, the patient's symptoms were unchanged for the 3 weeks that preceded her initial hospital visit. At her first follow-up visit after 6 weeks, the sensory changes in her buttock persisted, and follow-up NCS showed no SNAP in the right posterior femoral cutaneous nerve.…”

“…5 Tong and Haig first confirmed isolated PFCN neuropathy electrophysiologically using the Dumitru and Nelson technique in a patient who developed symptoms after an intragluteal injection. 1 Isolated PFCN neuropathy is known to occur in situations that promote compression of this nerve, such as hematoma or tumor formation in the presacral regions, prolonged bicycling, and falls on the buttock.…”

“…Despite its gluteal location and close proximity to the sciatic nerve, there have only been 9 reported cases in the modern literature. A Medline search covering the period from 1968 to 2008 found 3 cases caused by injection, 1 5 caused by compression, 2,3 and 1 with unknown etiology. 4 Four cases were documented clinically by electrophysiological testing.…”

Treatment of acute abdominal pain in the emergency room: A systematic review of the literature

“…In cases of acute abdominal pain in which compromised enteric absorption is suspected, intravenous analgesic administration should be achieved in order to bypass the gastrointestinal system and attain rapid onset of effect (Feifel, 1985;Stork and Hofmann-Kiefer, 2009). Alternative parenteral administration routes, such as intramuscular injection, should be avoided given the potential risks of neural and vascular injury, but may be necessary for prompt pain relief if intravenous access cannot be obtained (Greenblatt and Koch-Weser, 1976;Müller-Vahl, 1983;Tong and Haig, 2000; Deutsche Interdisziplinäre Vereinigung für Schmerztherapie (DIVS) et al, 2008).…”

High-resolution ultrasound of the posterior femoral cutaneous nerve: visualization and initial experience with patients

“…Most reports of nerve injuries regarding the PFCN are caused by intramuscular injections, although there are also reports of injuries to the PFCN due to hematoma, tumor formation, prolonged cycling, falls on the ground, entrapment of the PFCN in the facia lata, abnormal venous formations, and compression of the nerve against the sciatic tuberosity [3][4][5][6][7][8][9][10][11].…”
