11/67. cauda equina syndrome due to an intra-dural sacral cyst in type-1 gaucher disease.

    The authors report a rare case of type-1 gaucher disease with neurological and haematological involvement. The first onset was epilepsy, the diagnosis of GD1 was then confirmed and the patient experienced parkinsonism. The biological analysis revealed monoclonal gammapathy and factor-II mutation. The patient's condition worsened due to cauda equina syndrome. magnetic resonance imaging and surgery revealed an intra-thecal sacral cyst which, to our knowledge, has not been reported previously; therefore, when confronted with the fractures commonly observed in GD1, other unusual causes of spinal cord and root compression should not be overlooked.

12/67. neck mass after catheterization of a neck vein in a child with ventriculoperitoneal shunt.

    There have been many reports on various mechanical complications after shunt operations in children with hydrocephalus such as catheter fracture, obstruction, disconnection, dislocation and so on. However, there are no previous reports regarding subcutaneous mass formation due to cerebrospinal fluid (CSF) pseudocyst from direct puncture injury. The authors report with a review of the literature a case of a child with ventriculoperitoneal shunt who developed a neck mass after catheterization of the neck vein. The authors also advocate that percutaneous procedures in the vicinity of shunts be avoided whenever possible to prevent the possibility of CSF leakage resulting in pseudocyst formation.

13/67. Parapharyngeal neuroglial heterotopia presenting as a growing single locular cyst: MR imaging findings.

    Heterotopic brain presenting as a giant, growing, single locular cyst at the parapharyngeal space has not been reported before, to our knowledge. We present such a case, with MR imaging findings, in a 13-month-old girl. A well-demarcated giant cystic mass was noted in the left parapharyngeal space from the skull base to the submandibular region. Airway compression and deformity of the left mandible with subluxation of the temporomandibular joint were noted. The cyst contained a clear fluid that was isointense to CSF with all pulse sequences. Wall enhancement was noted on contrast-enhanced T1-weighted images. No connection to intracranial structures was noted. Histologic findings were compatible with neuroglial heterotopia.

14/67. Paget disease and sensorineural hearing loss associated with spiral ligament degeneration.

    HYPOTHESIS: Previously unreported cystic degeneration of the spiral ligament in cases of Paget disease. BACKGROUND: About 70% of cases of Paget disease involve the skull, with hearing affected in approximately 50% of these. The hearing impairment may be sensorineural, mixed, or, rarely, only conductive. The etiology and pathogenesis of the hearing loss are not yet understood, and reports in the literature are inconsistent regarding the pathologic changes responsible for sensorineural hearing loss. Of six pairs of temporal bones from patients with Paget disease in the temporal bone collection of a research institution, two pairs have abnormalities not previously associated with sensorineural hearing loss or Paget disease. We report the histopathologic findings in these temporal bones. methods: The temporal bones were fixed in formalin, decalcified in ethylenediaminetetraacetic acid, embedded in celloidin, and sectioned in the horizontal plane at a thickness of 20 microm. Every 10th section was stained with hematoxylin-eosin and mounted on glass slides. The sections were examined by light microscopy. RESULTS: Cystic degeneration of the spiral ligament, primarily in the basal segment, was found in both cases. endolymphatic hydrops and a small endolymphatic sac with calcification of the perisaccular tissue were found in one case. CONCLUSIONS: Cystic degeneration of the spiral ligament has not been previously reported and may be unique to Paget disease. This is consistent with recent literature showing a previously unsuspected role of the spiral ligament in sensorineural hearing loss.

15/67. Retroperitoneal lymphocele associated with lumbar spine fracture: report of an unusual case.

    DESIGN:To describe a case of retroperitoneal lymphocele as an extremely rare complication after lumbar spine fracture.OBJECTIVE:To discuss the possible mechanism of development of retroperitoneal lymphocele following blunt trauma to the ureter and lumbar spine.SETTING:Fukui University Hospital, Fukui, japan.RESULTS:A 71-year-old man presented with severe intractable low back pain caused by a huge retroperitoneal lymphocele, which was considered to be related to an occult L4 vertebral fracture and a blunt ureteral injury. The retroperitoneal lymphocele also caused significant instability at L3-4 level, thus requiring surgical resection followed by interbody fusion.CONCLUSION:physicians should be aware that such unusual retroperitoneal lymphocele might develop even after a blunt ureteral injury or a minor lumbar spine fracture.

16/67. Pelvic insufficiency fracture related to autosomal dominant polycystic kidney disease.

    We report the case of a patient with autosomal dominant polycystic kidney disease (ADPKD) and an insufficiency-type fracture of the pelvis. A 60-year-old Japanese woman was admitted because of pain in the right ischium and pubis that began suddenly with no precipitating cause. Computed tomography showed the bony pelvis to be compressed by enlarged dependent kidneys and an enlarged liver. We relieved compression on the pelvic bones by means of transarterial embolization (TAE) to the kidneys and liver after initiation of hemodialysis therapy. The fracture healed gradually after TAE, and the patient could walk 4 months later. In an iliac bone specimen obtained before TAE, cancellous bone was intact, but periosteal and endosteal surfaces of cortical bone showed marked resorption and were irregular. Normally, many ligaments are connected tightly to the periosteal surface, supporting the cortical bone. However, because of extensive surface resorption associated with pressure from enlarged kidneys, connections between ligaments and the periosteal surface presumably became fragile, promoting an insufficiency fracture from unapparent external forces. Thus, ADPKD is a potential cause of insufficiency fracture owing to abnormalities of cortical bone.

17/67. Posttraumatic cerebrospinal fluid cyst of the orbit.

    A 41-year-old woman had a motor vehicle accident and sustained a fracture of the left temporal bone with anterior and middle skull base involvement. After 10 months, she developed persistent right-sided exophthalmus. Orbital computed tomography scans showed a soft tissue mass in the roof of the right orbit with an inferior calcified border. The surgery revealed a cerebrospinal fluid cyst with intracranial communication through the fistula in the posterior orbital roof.

18/67. Retroperitoneal cysts: a case report.

    Retroperitoneal cysts are rare lesions, variable from asymptomatic cases with incidental discovery to case with acute or chronic abdominal discomfort. A 50-year-old female after a car crash refered chronic abdominal pain. An X-ray revealed the presence of sternal and multiple costal fractures. Abdominal ultrasonography (US) and computed tomography (CT) lead to the discovery of a retroperitoneal cyst too. As the patient was well after fractures solution, we decided to control the cyst in the time. In symptomatic cases surgery is the treatment of choice. The advent of laparoscopic surgery allows resection of these cysts to be achieved without full laparotomy.

19/67. Orbital cysts lined with both stratified squamous and columnar epithelia: a late complication of silicone implants.

    Two patients presented with orbital cysts 5 and 7 years after orbital blowout fracture repair with silicone plate implants. The orbital cysts caused significant exophthalmos and restriction in ocular motility. Surgical excision revealed thick-walled cysts that were displacing the globe and encapsulating the silicone implant. On histopathologic examination, the cysts were lined with both stratified squamous and ciliated columnar (respiratory) epithelia. We propose that squamous and respiratory epithelial cells may have been deposited during surgery from the conjunctival and sinus epithelia, respectively. This case series illustrates that although an uncommon complication, epithelium-lined inclusion cysts may develop several years after orbital fracture repair with a silicone implant. A transconjunctival surgical approach is a possible risk factor.

20/67. Unusual posttraumatic porencephaly--case report.

    An unusual case of posttraumatic porencephaly preceded by neither overt cerebral contusion nor hemorrhage is reported. The cerebral cortex just above the porencephalic cyst was found intra-operatively to be partially herniated into a fracture line, while the cortex elsewhere was completely intact. The porencephalic cyst communicated with the lateral ventricle. Apparently, brain herniation and the cyst-ventricle communication can be causative factors in the occurrence and growth of posttraumatic porencephaly.
