Cavernous hemangioma of the parietal bone. A case report.

Intraosseous cavernous hemangiomas are a rare finding in the calvarium. It is a benign tumors arising from the intrinsic vasculature of the bone. We report one case observed in a 31 year-old female, presented with a progressive left parietal mass. A plain X-ray of the skull and cranial CT-scan showed a osteolytic lesion in the left parietal bone. Surgery consisted of total resection of the lesion and cranioplasty. The postoperative course was uneventful. Histological study revealed a cavernous hemangioma of the diploe. In view of this observation and the literature review, clinical; radiological and therapeutic aspect of this rare entity are discussed.

[Chronic lumbar pain considered to be "nephretic colic" after 7 years, due to a thoracic disc herniation at T10-11].

The authors report the case of a 35-years-women with a thoracic disc herniation, who presented with seven years history of episodic acute ureteric colic. An early diagnosis of a spinal disc herniation was made difficult by the absence of neurological findings. Imaging studies showed no lesion in the genito-urinary tract. Magnetic resonance imaging demonstrated a postero-lateral disc herniation at T10-T11 level. The pain disappeared immediately after surgery decompression. A literature search showed that acute ureteric colic associated with a lower thoracic disc herniation has not been previously reported.

Cerebellar liponeurocytoma (lipomatous medulloblastoma).

Liponeurocytoma (lipomatous medulloblastoma) is an uncommon clinicopathologic entity. We report a case of cerebellar liponeurocytoma in an adult and attempt to better characterize this uncommon lesion. A 43-year-old woman presented with symptoms and signs of increased intracranial pressure and cerebellar dysfunction. CT and MRI showed a heterogeneous well-circumscribed mass in the left cerebellar hemisphere with hydrocephalus. Complete surgical excision of the tumor was accomplished through a suboccipital craniotomy. Pathological examination with immunohistochemical study revealed a medulloblastoma with neuronal, astrocytic and lipomatous differentiation. Postoperative radiation therapy was given. After surgery, the patient was followed up for a 16 month-period; symptoms improved dramatically and no evidence of tumor recurrence was found. Careful analysis of the histopathological and immunohistochemical studies correctly identifies liponeurocytoma (lipomatous medulloblastoma). To our knowledge, only 16 cases have been reported. Although this lesion appears to have a better prognosis than the conventional form of adult medulloblastoma, complete surgical removal with postoperative radiation therapy is recommended.

[Giant epidermoid cyst of the skull with extra and intracranial extension. A case report].

Intradiploic epidermoid cyst of the skull is a rare clinical entity that can exceptionally grow to a large size with intracranial extension. The authors report the case of a 38-year-old man with a giant epidermoid cyst of the parietal bone with extra and intracranial extension, presenting with focal neurological symptoms. The diagnosis was suggested at imaging (skull radiographs, CT and MRI), and confirmed at histology. Complete removal of the cyst and its capsule was performed followed by cranioplasty. Postoperatively, the patient was discharged free of symptoms. CT scan provides good evaluation of the bony lesion and may suggest intracranial extension. MRI is superior for evaluation of cerebral compression. The pathogenesis, clinical presentation, diagnostic evaluation and therapeutic management of these rare lesions are reviewed.

[Sphenotemporal aneurysmal bone cyst. A new case and review of the literature].

Aneurysmal bone cysts (ABC) are benign tumors of the bones, formed by multiple cysts filled with blood and eroding the bone. They are rarely located at the skull. We report a case of a right temporal ABC in a 5-year-old girl. On admission, the physical examination showed a tough and fixed tumor, with no inflammatory signs nor vascular characteristics. The neurological examination was normal. Imaging studies showed an heterogeneous extracerebral mass, eroding the temporal bone and the greater wing of the sphenoid bone. The treatment consisted in an extensive tumor resection, associated with reconstructive surgery. The outcome was uneventful (follow-up 27 months). We underline the pathogenetic, diagnostic and therapeutic features of this condition.

[Multiple cerebral hydatic cysts of cardiac origin. A case report].

The hydatic cyst is a pathology observed in developing countries. Multiple cerebral localizations with a cardiac origin are exceptional and are sometimes diagnosed only after onset of complications. We present the case of a 22-year-old male student: the diagnosis of multiple cerebral hydatic cysts caused by rupture of a cardiac hydatic cyst was established after an episode of ischemia of the limbs with cerebral hemorrhage induced by heparin. One year later, the clinical situation consisted in intracranial hypertension, hemiplegia and convulsive seizures. We observed no cardiac symptoms. The brain CT showed 9 hydatic cysts and echocardiography showed a myxomatous cystic tumor. Abdominal CT detected renal and splenic hydatic cysts. The patient underwent total ablation of the cerebral and abdominal cysts and made a full recovery. After surgical removal of the cardiac cyst, the patient has been lost to follow-up. Cerebral hydatidosis of cardiac origin is highly exceptional and, due to nonspecific symptomatology, may go undiagnosed. In general, prognosis is good in case of a cerebral localization but the cardiac localization is associated with high mortality.

[Anterior approach of cervical spine in Pott's disease. Apropos of 7 cases].

This study reports 7 cases of cervical Pott's disease, gathered during 6 years in the department of neuro-surgery of Ibn Rochd U.H.C. 4 females and 3 males, aged between 9 and 52 years were included. All the patients complained of cervicobrachial pain and weakness of the limbs. Clinical features were: deterioration of general status, rachidian syndrome and neurological impairement with motor and sensitive deficit. Radiological analysis found a destructive and extensive lesion, cervical kyphosis from 10 degrees to 60 degrees, retropharyngeal abscess and intraspinal canal extension of infection. Diagnosis was confirmed by histological study in all cases. In addition to antituberculous therapy and preoperative cervical traction in 4 cases, all the patients had spinal fusion using an anterior approach. Post operative immobilization in a cervical collar varied from 9 to 12 months. All 7 patients had full neurological recovery, 6 patients had an excellent bony fusion and cervical kyphosis was corrected. For the remaining patient, the bone graft was mobilized without neurological disorders. This study confirms anterior arthrodesis efficiency. This procedure in conjunction with preoperative traction, allowed stabilization of the spine and healing of vertebral lesions with excellent kyphosis correction.

[Hydatid cyst of the spine and spinal cord. Study of 24 cases].

In this retrospective study, we report our experience of severe hydatid disease located to the spine and the adjacent spinal cord observed in 24 cases between 1970 and 1994. In our series the sex ratio was predominant for males, and the mean age was 29 years. Clinically, the patients presented predominantly with a motor deficit. The diagnosis was assessed on radiological and biological investigations and was confirmed preoperatively. Hydatid serology was positive in 7 out of the ten cases explored. On standard X rays, the bone lesions were frequent: lysis in 10 cases, vertebral deformation in 3 cases, costal invasion in 5 cases, and paravertebral collection in 2 cases. These lesions were predominantly located at the thoracic level. Myelography confirmed a complete blockade in 8 out of 11 cases. When possible, the CT scan confirmed the bone lesion in all of the 10 cases explored, with an intrathecal cyst in 7 cases and a paravertebral collection in 8 cases. Magnetic resonance imaging was possible in one case only. Medical antihelminthic treatment was indicated as the sole treatment in one inoperable case. All the other patients were operated on, and the adjunctive specific medical treatment was associated in 5 cases. Using a posterior approach in 20 cases, the operative technique consisted in a complete removal (if possible) of the invaded bone and soft tissue, thus achieving a complete relief of the spinal cord compression. Complementary bone fixation was indicated in 2 cases. During the postoperative follow-up, two patients died from infection and trophic ulceration, 11 patients improved and 8 patients remained unchanged. In 5 cases, a reoperation was indicated and performed from 2 to 4 times. Three patients were lost for follow-up. The severity of this affection is confirmed in the literature. A complete recovery is quite exceptional. The best treatment remains an active nationwide prevention of the disease.

[Intradural extramedullary tuberculous abscess. Apropos of a case].

Intradural extramedullary tuberculous spinal abscess is rare and has a poor prognosis if not diagnosed early and treated adequately. We report the case of 13 year-old boy who presented with an 8-month history of paraplegia. MR imaging demonstrated an intradural extramedullary spinal abscess in the mid-thoracic region. At operation, an encapsulated abscess was removed completely. The tuberculous nature was confirmed with microbiological testing. Postoperative antituberculous chemotherapy resulted in complete recovery. MR imaging can prove very helpful in early diagnosis of this condition, which is particular relevant in countries where tuberculosis is endemic.

[Cystic meningioma in children. Apropos of a case].

A case of cystic meningioma in a 9-year old girl is reported. The initial clinical symptom was focal epilepsy, and this was followed by progressive hemiparesis. CT of the brain detected a calcified tumour to which two cysts were attached. The tumour was strongly enhanced by the contrast medium. Histology confirmed that the lesion was a meningioma of the psammous type. A review of the literature showed that this is a rare tumour the pathogenesis of which can be explained in various ways. Nautal's classification into 4 types is the most widely adopted. The diagnosis has been made in only 38% of the 166 cases published.

[Anal migration of ventriculo-peritoneal shunt catheter. Apropos of 3 cases].

Three cases of abdominal catheter migration through the anus following ventriculo-peritoneal shunt are described. Two cases involved hydrocephalus secondary to tuberculous meningitis and the third myelomeningocele. Among the reasons for migration, the length of the abdominal catheter, trauma during the operation and infection must be taken into consideration. One patient was suffering from meningitis at the time of admission, while the two others were asymptomatic. Treatment involved removing the peritoneal catheter in 2 cases and the entire shunt system in the patient with meningitis. The shunt was replaced one to two weeks later. The outcome was favourable in all three cases.

[Intra-orbital hydatid cysts. 10 cases].

Ten cases of intra-orbital hydatid cysts were operated from January 85 to December 91. The aim of this retrospective study is to show the importance of this pathology with regard to other intra-orbital expansive processes and to discuss the efficiency of neurosurgical approaches. The mean age was 25 years, with 5 women and 5 men. The symptoms consisted in progressive unilateral exophthalmia in 8 cases and acute one in 2 cases. Visual deterioration was observed in 7 cases: a reduced vision acuity in 6 cases and blindness in one case. Fundus oculi showed papillary oedema in 4 cases and optical atrophy in one case. Slight disturbance of ocular mobility was observed in 5 cases. CT Scan gave positive diagnosis and predicted the hydatid nature in 9 cases. Fronto-orbital approach, taking away the squamous portion of the frontal bone, orbital arc and roof, was made in 9 cases. It permitted to remove the cyst without rupture of the capsule in all cases. Fronto-temporal approach was used in one case. The evolution was excellent after 8 months to 6 years in 4 patients. Five patients were improved with reduction of exophthalmia, stabilisation of visual acuity and eye movements. Blindness remained unchanged in one patient.
