1/189. peroneal nerve palsy caused by intraneural ganglion.

    A case of peroneal nerve palsy caused by an intraneural ganglion is presented. The cystic mass was located posterolateral to the lateral femoral condyle and extended along the common peroneal nerve distal to the origin of the peroneus longus muscle. The nerve was compressed in the narrow fibro-osseous tunnel against the fibula neck and the tight origin of the peroneus longus muscle. The nerve was decompressed by complete tumor excision and transection of the origin of the peroneus longus muscle. Full recovery of nerve function was obtained in 6 months.

2/189. Posterior fossa epithelial cyst: case report and review of the literature.

    A 49-year old woman with progressive cranial nerve signs and hemiparesis was found at MR imaging and at surgery to have a cyst at the foramen magnum. immunohistochemistry and electron microscopy showed an epithelial cyst of endodermal origin. MR findings were of an extraaxial mass, with short T1 and T2 times. Unless immunohistochemistry and electron microscopy are used in the final diagnosis of such cysts, all posterior fossa cysts lined by a single layer of epithelium should be described simply as epithelial cysts.

3/189. Sacral nerve root cysts: A review on pathophysiology.

    Nerve root cysts of the sacral region are generally asymptomatic but are known to cause neurogenic claudication. In this paper we present an elderly lady who presented with claudication, whose MR imaging showed a sacral cyst. She underwent lumbo-sacral laminectomy, partial excision of the cyst wall with plication. A review of the possible pathophysiology of such a lesion is discussed.

4/189. Congenital intraorbital optic nerve cyst. Case report.

    Congenital cystic lesions of the optic nerve are exceedingly rare; only one case is reported in the world literature. The authors describe a case of congenital simple glial cyst in the intraorbital portion of the optic nerve with a brief review of the literature and comment on its histogenesis. A 45-day-old male infant was admitted to the hospital because of progressive proptosis and hypotropia in the left eye, which had been present since birth. magnetic resonance imaging of the left orbit revealed an ovoid, well-demarcated, homogeneous cystic mass in the intraconal retrobulbar area. The mass compressed the left eyeball with downward and lateral displacement. The wall of the cystic mass was very thin, and a needle puncture of the cyst released clear, colorless, watery fluid. The cystic wall was lined by loose astroglial nerve fibers with some scattered glial cells.

5/189. ehlers-danlos syndrome associated with multiple spinal meningeal cysts--case report.

    A 40-year-old female with ehlers-danlos syndrome was admitted because of a large pelvic mass. Radiological examination revealed multiple spinal meningeal cysts. The first operation through a laminectomy revealed that the cysts originated from dilated dural sleeves containing nerve roots. Packing of dilated sleeves was inadequate. Finally the cysts were oversewed through a laparotomy. The cysts were reduced, but the postoperative course was complicated by poor wound healing and diffuse muscle atrophy. ehlers-danlos syndrome associated with spinal cysts may be best treated by endoscopic surgery.

6/189. An unusual site for the AV node tumor: report of two cases.

    Atrioventricular (AV) node tumors are very uncommon primary cardiac tumors located exclusively in the AV nodal region. The nomenclature has been diverse according to different histogenetic theories proposed since the first description in 1911. Histochemical, ultrastructural, and immunohistochemical studies have demonstrated its endodermal origin. patients with these tumors can develop complete heart block or sudden death, but the tumor can also be an incidental finding at autopsy. We present two accidental deaths cases in which multiple foci of atrioventricular node tumor (Case 1) and an isolated cyst (Case 2) were observed in the atrial septum, sparing the conduction system.

7/189. Cystic schwannomas of the jugular foramen: clinical and surgical remarks.

    OBJECTIVE: The goals of this report were to outline the clinical presentation, radiological characteristics, surgical techniques, postoperative morbidity, and long-term follow-up results for cystic jugular foramen (JF) schwannomas and to describe their differences, compared with solid schwannomas involving the JF. methods: A retrospective analysis of radiological studies and surgical records identified five primarily cystic tumors among 21 cases of JF schwannomas that had been surgically treated at our institution. RESULTS: Two types of cystic JF schwannomas were observed, i.e., Type 1 lesions, which are single large cysts with thin ring-like enhancement of the tumor wall, and Type 2 lesions, which are multiple cysts with very irregular, thick enhancement of the cyst wall. The most common symptoms were hearing loss, ataxia, and headaches. Total surgical removal could be performed in all cases. The immediate postoperative findings indicated hearing improvement in three cases. No deterioration of lower cranial nerve function was observed. All patients were independent in the immediate postoperative period and in the long-term follow-up period (Karnofsky Performance Scale score, 90). CONCLUSION: Surgical treatment of cystic JF schwannomas can be very demanding because of generally stronger adhesion of the tumor capsule to the surrounding structures, fragile tumor capsules, and difficulty in identification of the arachnoidal planes in some cases. Early identification of the arachnoidal planes without opening of the cyst and sharp dissection may be useful. Careful intradural opening of the JF should be performed to achieve total removal of the last tumor portion within the JF. A comparison of these lesions with solid schwannomas involving the JF indicated that cystic tumors affected a younger population, with less preoperative swallowing impairment (P < 0.05). The immediate postoperative course in both types of cystic JF schwannomas was usually better than for solid lesions, because of minor postoperative cranial nerve morbidity, especially involving lower cranial nerve function, in the latter cases. Long-term follow-up data failed to demonstrate any significant differences in final patient outcomes, however.

8/189. Congenital cystic tumors of the atrio-ventricular node: successful demonstration by an abbreviated dissection of the conduction system.

    Pathologists are dissuaded from the pathological study of the conduction system by the high cost and complexity of a traditional complete study. However, a simplified, low-cost approach can produce concrete information when performed in carefully selected cases of atrioventricular block, as demonstrated in the two cases of congenital cystic tumor of the atrioventricular node described in this report.

9/189. A benign parathyroid cyst presenting with hoarse voice.

    Parathyroid tumours and cysts are rare and, when presenting as neck masses, can be clinically misdiagnosed as thyroid lesions. Symptoms may be caused by compression of the surrounding structures or hormonal overactivity. This paper describes a patient with recurrent hoarseness owing to the pressure effects of a parathyroid cyst on the recurrent laryngeal nerve.

10/189. optic nerve coloboma with retinal degeneration associated with cystic microphthalmia of the other eye.

    In a seventy-five-year old man an optic nerve coloboma with generalised retinal degeneration associated with a cystic microphthalmia of the other eye is described. The MR imaging revealed the existence of a left microphthalmic eye with a lower lid cyst. From the other eye an optic nerve coloboma with a cystic ectasia of the coloboma area freely open to the vitreous cavity was apparent. The ERG recorded from this eye was extinguished.
