We report 2 cases of a popliteal mass of very unusual origin that induced compression neuropathy. The signs and symptoms could have been mistaken for those of a common Baker's cyst. Several recent studies have shown that the cause of Baker's cyst formation should be sought within the joint because of a communication between the gastrocnemio-semimembranosus bursa and the joint cavity. These 2 cy...

nerve entrapment at the wrist or hand that can cause motor, sensory or combined motor and sensory loss depending on the localization of entrapment along the canal. The most common etiological factor is the compression of the ulnar nerve at the wrist by a ganglion. However, other conditions such as anomalous musculotendinous arches, lipomas, diseases of the ulnar artery, fractures of the hamate,...

Purpose. To present a unique case of Non-Hodgkin's-Lymphoma- (NHL) associated compressive optic neuropathy. Method. An 89-year-old male presenting with acute unilateral visual loss and headache. Results. Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasa...

We present a case of a 69-year-old woman who developed brachial plexopathy and long thoracic nerve palsy secondary to compression from a hematoma while receiving heparin therapy for the treatment of a stroke. The patient was treated conservatively with discontinuation of heparin and had complete resolution of her compressive neuropathy. This is the first report of a patient with long thoracic n...

Carpal tunnel syndrome has a prevalence of 1% to 10%, and while acute carpal tunnel syndrome makes up the minority of cases of this compression neuropathy, it is important to recognize as a distinct entity because prompt surgical treatment can decrease long-term morbidity. The most common causes of acute carpal tunnel syndrome are trauma to the hand or wrist, infection, and disorders of rheumat...

Carpal tunnel syndrome (CTS) is a common focal peripheral neuropathy. Increased pressure in the carpal tunnel results in median nerve compression and impaired nerve perfusion, leading to discomfort and paresthesia in the affected hand. Surgical division of the transverse carpal ligament is preferred in severe cases of CTS and should be considered when conservative measures fail. A through knowl...

Carpal tunnel syndrome is the most common entrapment neuropathy seen in the electrodiagnostic laboratory. Clinical assessment is an important part of the electrodiagnostic consultation and helps to form an appropriate differential diagnosis. Sensory conduction studies are a critical part of the evaluation. Using a summary index, such as the combined sensory index, is preferable to considering s...

Ulnar nerve variations in the wrist are rare but still have clinical importance. In the course of a routine dissection of the right hand of a 67-y-old Caucasian male cadaver an aberrant ulnar nerve at the wrist was found. Its superficial branch bifurcated and formed a complete loop around the hook of the hamate bone. The sensory digital nerves arose from the different parts of this loop. The pr...

Piriformis Syndrome (PS) is an uncommon, controversial neuromuscular disorder that is presumed to be a compression neuropathy of the sciatic nerve at the level of the piriformis muscle (PM). The diagnosis is hampered by a lack of agreed upon clinical criteria and a lack of definitive investigations such as imaging or electrodiagnostic testing. Treatment has focused on stretching, physical thera...

Extracorporeal shock wave lithotripsy (ESWL) is the gold standard treatment for ureteral calculosis. Radial neuropathy related to anesthetic or surgical procedures is a very rare complication and it is generally related to compression factors1. To date and to our knowledge, there are no descriptions of radial nerve lesion after ESWL procedure. A 36 years old female patient (61 Kg) with ureter c...
