Femoral nerve compression secondary to a ganglion cyst arising from a hip joint: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Femoral nerve compression due to a cystic lesion around the hip joint is rare and only a few cases have been described in the literature. Among these, true ganglion cysts are even more rare.</p> <p>Case presentation</p> <p>We report the case of a 57-year-old woman with femoral nerve compression caused by a true ganglion cyst of the hip joint.</p> <p>Conclusion</p> <p>A high index of suspicion is required to predict a non-palpable cystic lesion around the hip joint as it may mimic different disorders and should be kept in mind in the differential diagnosis of unusual groin pain, radicular pain and peripheral vascular disorders.</p

Femoral neuropathy caused by an iliopsoas bursal cyst

✓ This case presents a rare occurrence of femoral neuropathy due to iliopsoas bursitis as a consequence of hip osteoarthritis. A computerized tomography scan of the hip revealed a smooth-walled nonenhancing cystic mass adjacent to the hip joint and elevating the components of the homolateral femoral triangle. The differential diagnosis and operative management of this entity are reviewed.</jats:p

Limitations of diazoxide reversal of vasospasm

Diazoxide failed to safely relieve cerebral vasospasm by intracisternal injections in dogs and by intracarotid injections in monkeys despite in vitro documentation of arterial relaxation with this agent. Administration of the drug frequently produced hypotension and, in the presence of vasospasm, was associated with a high mortality rate

Reversal of experimental cerebral vasospasm by intravenous nitroprusside therapy

Cerebral vasospasm was induced in dogs by intracisternal injection of blood. After angiographic demonstration of spasm, sodium nitroprusside was infused intravenously and its effect on the diameter of the basilar artery was studied angiographically. Ten experiments were performed within 90 minutes of the induction of spasm and nine experiments were performed 24 or 48 hours later. Significant dilatation of the basilar artery was achieved in all cases and it persisted for as long as the infusion of nitroprusside continued. The drug produced a modest degree of systemic hypotension. In six experiments it was possible to avoid hypotension by a simultaneous infusion of dopamine

Does the CO2 laser spread viable brain-tumor cells outside the surgical field?

✓ The viability of debris containing C6 rat tumor cells generated by the CO2 laser was investigated using standard tissue culture techniques. No evidence of cell viability was found in the plume of laser smoke.</jats:p
