Concurrent meralgia paresthetica and radiculopathy of the left leg: A case report

Meralgia paresthetica (MP) is a painful mononeuropathy of the lateral femoral cutaneouse nerve (LFCN) characterized by localized symptoms of numbness, tingling, pain and paresthesia along the anterolateral thigh area. L4 and L5 radiculopathy is set of symptoms that include sharp, burning or shooting pain, which is usually localized to anterolateral leg area and along the dermatomal distribution. When symptoms of MP and lumbar disc disease occur together it is not easy to diagnose MP. We report a case of synchronous post-traumatic MP and radiculopathy due to intervertebral disc herniation at L3–4 and 4–5. A 59-year-old male patient was admitted to the emergency room with symptoms of low back pain with left severe L4, L5 radiculopathy. This patient also complained of numbness and paresthesia in the left anterolateral thigh. After detailed history taking and lateral femoral cutaneouse nerve block, he was diagnosed with MP.

Perioperative anesthetic management of a patient with catecholamine-secreting paraganglioma: A case report

Paraganglioma is an uncommon neuroendocrine tumor of cells that originate in the autonomic nervous system. Some paragangliomas have the ability to secrete catecholamines, similar to secretions in pheochromocytoma. For this reason, paragangliomas may cause malignant hypertension in patient, upon being administered anesthesia, or during surgery, this may lead to a life-threatening condition, despite the tumor having been diagnosed before conducting the procedure. Therefore, it is important to take adequate actions for reducing the occurrence of morbidity and mortality during surgery. Here, we describe a successful anesthetic management in a patient diagnosed with retroperitoneal paraganglioma invading the iliac bone.

A brief report on a technical description of ultrasound-guided lumbar sympathetic block

The lumbar sympathetic ganglion block (LSGB) is widely used for diagnosing and treating sympathetically maintained pain disorders. The LSGB has been conventionally carried out under fluoroscopy or computed tomography guidance. However, as ultrasound technology improved, ultrasound-guided interventions have been expanding their territory to deeper structures. Ultrasound guidance provides many benefits including protecting vascular injection, shortening procedure time in some cases, and reducing the emission of radiation. In this report, we describe a successful case of a US-guided LSGB without major complications. We expect that US-guided LSGBs can be implemented and furnished in the daily outpatient clinical setting by highly trained pain physicians.
