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 case of cervical radiculomyelopathy was caused by calcification of the ligamentum flavum of the cervical spine. A 63-year-old woman with dysesthesia on both upper extremities and gait disturbance was transferred to our hospital. Neurologic examimation revealed only mild right hemiparesis, while a plain cervical X-ray and a computed tomogram revealed nodular calcification in the posterior paramedial portion of the spinal canal at the level of C3-4. A well-defined low signal intensity mass on T1- and T2-weighted MR images demonstrated severe posterior compression of the spinal cord. The nodular mass together with the ligamentum flavum was removed by partial inferior laminectomy of C3 and partial superior laminectomy of C4. The calcified mass, confined within the ligamentum flavum, was composed of numerous fine amorphous particles and chalky white substances with a paste-like consistency, and caused marked underlying spinal cord compression. It had no connection, however, with the lamina or dura mater. The patient's neurological deficits were resolved two weeks after surgery. A clinical summary of the case and review of the corresponding literature are presented

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.
