Sciatic nerve compression due to a ganglion cyst around the posterior aspect of the hip joint is not commonly described in literature. We report a rare case of a 63-year-old man with a ganglion cyst around his hip joint, who presented with symptoms of sciatica. After excision of the cyst, the patient was symptom free. A high index of clinical doubt and detailed clinical examination is required for non-palpable cystic lesions in close proximity to the sciatic nerve in patients presenting with symptoms of sciatica and in patients with concomitant of lumbar disk herniation.

“…A T2-weighted MRI may show high signal intensity in the nerve and/or increased nerve diameter. 7 In the present case, we used MRI to localize the precise level of the nerve injury, and MRI results showed bilateral sciatic nerve swelling from the level of the superior gemellus to the level of the quadratus femoris. Although ultrasonographic evaluation may offer some useful information about the site of nerve injury, the ultrasonographic interpretation criteria for identifying traumatic nerve abnormalities have not been clearly defined in the literature.…”

Purpose Sciatic neuropathy is a rare but serious complication of cardiac surgery. Neuropathic pain following nerve injury can be severely debilitating and largely resistant to treatment. We present a case of this complication where ultrasound-guided perineural steroid injection at the site of the sciatic nerve injury provided excellent pain relief and facilitated subsequent rehabilitation. Clinical features A 17-yr-old boy developed bilateral sciatic neuropathy after a nine-hour cardiac surgical procedure in the supine position, resulting in debilitating dysesthesia refractory to neuropathic pain therapies and leading to severe functional limitation. With magnetic resonance imaging of the lower extremities, the location of the lesion was determined to be from the level of the superior gemellus to the level of the quadratus femoris. An ultrasound-guided injection of triamcinolone 20 mg and lidocaine 40 mg around both sciatic nerves at the level of the lesion was administered two months after the surgery, and the pain score (rated on a scale 0-10) at rest decreased from 9-10 to 1 two weeks after the injection. Conclusions There are a limited number of reports in the literature on sciatic nerve injuries associated with cardiac surgery. This case illustrates the efficacy of ultrasoundguided steroid injection around sciatic nerves at the level of superior gemellus in treating our patient's neuropathic pain. RésuméObjectif La neuropathie sciatique est une complication rare mais grave de la chirurgie cardiaque. La douleur neuropathique suivant une lésion nerveuse peut être extrêmement débilitante et très résistante au traitement. Nous présentons un cas de cette complication dans lequel l'injection périneurale échoguidée de stéroïdes au site de la lésion du nerf sciatique a fourni un excellent soulagement de la douleur et facilité la réhabilitation subséquente. É léments cliniques Un garçon de 17 ans a commencé à souffrir de neuropathie sciatique bilatérale après une intervention chirurgicale cardiaque de 9 heures en position dorsale, résultant en une dysesthésie débilitante réfractaire aux traitements contre la douleur neuropathique et entraînant des limites fonctionnelles graves. En réalisant une imagerie par résonance magnétique des membres inférieurs, on a pu déterminer l'emplacement de la lésion, allant du muscle jumeau supérieur au muscle carré fémoral. Une injection échoguidée de triamcinolone 20 mg et de lidocaïne 40 mg autour des deux nerfs Author contributions Jia-Chi Wang authored the first draft of the manuscript. Rai-chi Chan and Tsui-Fen Yang provided guidance and critically reviewed the manuscript. Hong-Jen Chiou, Jen-Her Lu, and Yung-Cheng Hsu were involved in the initial care of the patient, interpretation of the clinical case, and manuscript preparation.
