Intracranial Solitary Fibrous Tumour Management: A French Multicentre Retrospective Study.

Background: Intracranial solitary fibrous tumour (iSFT) is an exceptional mesenchymal tumour with high recurrence rates. We aimed to analyse the clinical outcomes of newly diagnosed and recurrent iSFTs.

Methods: We carried out a French retrospective multicentre ( = 16) study of histologically proven iSFT cases.

[Epithelioid hemangioendothelioma of the spine: A case report].

Epithelioid hemangioendothelioma is a rare vascular tumour, with features between hemangiomas and angiosarcomas. Evolution remains mainly local but may also metastasize. Here, we report a case of a patient with a spinal epithelioid hemangioendothelioma.

Secondary metabolites from Eryngium species.

From the seed and leaf extracts of Eryngium species, two new compounds were isolated, along with an aliphatic ketone and several known terpenoids reported from a member of Umbelliferae for the first time. Their structures were elucidated by chemical methods and spectroscopic analysis.

A new irregular diterpenoid from Opopanax chironium.

The ethereal extract of the roots of Opopanax chironium yielded peucelinenoxide acetate (1), a new natural product with an irregular diterpene skeleton, besides the known coumarins gaudichaudin, columbianadin, peucedanin and officinalin isobutyrate.

Germacranolides from seeds of the endangered Umbelliferae species Rouya polygama.

From the etheral extract of Rouya polygama Coincy seeds (Umbelliferae) six new germacranolides 1-6 were isolated. The structures were elucidated by chemical methods and spectroscopic analysis. Compounds 1 and 4 exhibited activity against Artemia salina larvae.

[Giant sacral schwannoma with pelvic extension. Therapeutic strategy. Apropos of a case].

A 48-year-old woman was admitted for acute urinary retention. Clinical pelvic examination disclosed a voluminous retro-rectal mass. Plain X-rays, pelvic echography, computerized tomography and MRI were all consistent demonstrating the presence of a 15cm-diameter lesion in the pelvic space with sacral erosion at S3-S4 and extension in the sacral canal up to S2.

[Thoracic spondylotic myelopathies. Apropos of 4 new cases].

Four cases of thoracic spondylotic myelopathy are reported, one man and three women, respectively 61, 66, 67 and 76 years old. Clinical presentation was numbness and weakness in the lower limbs in two cases, weakness alone in one and numbness alone in the last one. Diagnosis was settled by both myelography and CT-myelogram in three cases, by both MRI and CT-scan in the other one.

[Meningeal melanocytoma or multiple pigmented meningioma of the spinal canal. Report of a case. Review of the literature].

In a 64-year-old male with pain and weakness of the right lower limb, investigations disclosed a cervical tumor, several dorsal tumors, and tumoral infiltration of the lumbosacral area. Histological and, above all, immunohistochemical and ultrastructural features were suggestive of meningeal melanocytoma. Before the use of immunohistochemical and electron microscopy techniques, meningeal melanocytoma was designated by the term pigmented meningioma because its histological features bear some resemblance to those of meningioma.

[Ependymoma of the intradural filum terminale in adults. 20 cases].

Twenty cases of ependymomas of the intradural filum terminale in adults have been reviewed. Their pathology was quite uniform, of a myxopapillary type, similar to the low grade ependymoma described by Kernohan, which represent about 23% of the tumours of cauda equina. Mean age of the patients was 35.

[Recurrent intracranial hematomas disclosing Rendu-Osler disease in a pregnant woman].

The authors report on the case of a young woman, seven months gone, with an history of sudden onset of successive lobar intracerebral hematomas. They revealed a Rendu-Osler-Weber disease. The mechanism is discussed.

[Myelo-radicular involvement in a lumbar foramen disk hernia].

The authors report a case of L4-L5 foraminal disc herniation revealed by symptoms of bi-radicular and medullary lesions. Anatomical study allows to understand such association of symptoms.

[Acute intracranial subdural hematoma after accidental dural puncture in epidural anesthesia].

A case is reported of an acute intracranial subdural haematoma following an accidental dural puncture during an epidural anaesthesia. A seventy-year old man, class ASA I, was operated on for prostatic adenoma under epidural anaesthesia. Dural puncture occurred during the first introduction of the needle into the L4-L5 epidural space.

[Neurinoma of the oculomotor nerve. Apropos of a case].

A case of a surgically verified neurinoma of the oculomotor nerve is presented. The diagnostic difficulties due to the parasellar localisation are discussed. Computed tomography scan data rarely allow to distinguish the nature of the tumor and in all cases are insufficient to distinguish a trigeminal nerve neurinoma of the oculomotor nerves.

[Intracranial hypertension and hydrocephalus caused by spinal cord tumors. Apropos of 3 cases].

Three cases of spinal cord tumor, revealed by hydrocephalus, are reported. Two patients showed symptoms of increased intracranial pressure and the third one presented himself with ataxic gait without intellectual impairment nor incontinence. In two cases ventriculo atrial shunt was initially inserted and the correct diagnosis was made only later on myelogram because lombosciatalgia or syndrome of the cauda equina.

[Deglutition disorders caused by an injury to the foramen lacerum posterior].

Dysphagia due to a traumatic lesion of the foramen lacerum posterior is relatively rare. Two cases are described in which swallowing troubles were perceived when the post-traumatic coma improved; these were ascribed to a traumatic lesion of the foramen lacerum posterior injuring the cranial nerves. Treatment involves preventing inhalation and nasogastric feeding whilst starting active and early rehabilitation of swallowing.
