OBJECTIVE: To evaluate the clinical, endocrinological, and radiological presentation of nine cases of surgically verified intrasellar arachnoid cysts and to discuss the physiopathological mechanisms of formation of these cysts. METHODS: Among 1540 patients presenting with pituitary lesions, nine presented with an intrasellar arachnoid cyst. Their charts were retrospectively reviewed. RESULTS: Presenting symptoms included headache (n = 2), visual symptoms (n = 3), menstrual irregularities (n = 2), rapid weight gain (n = 1), vertigo (n = 1), and/or confusion (n = 1). Two cysts were discovered incidentally. T1-weighted magnetic resonance imaging scans showed an intrasellar cystic lesion in all cases, with a huge suprasellar extension in six cases. The cyst was of the same intensity as the cerebrospinal fluid (CSF) in only two patients. A transsphenoidal approach allowed the transdural aspiration of fluid and injection of a water-soluble contrast agent under mild pressure. In three patients, the contrast infiltrated along the pituitary stalk toward the subarachnoid spaces; in the other patients, it remained in the intrasellar compartment. Cyst membranes were removed as completely as possible with fenestration toward the subarachnoid spaces in communicating cysts. In spite of tight packing of the sella and sphenoid sinus, CSF fistulae requiring reoperation developed in two patients. CONCLUSION: The clinical picture of an intrasellar arachnoid cyst resembles that of a nonfunctional pituitary adenoma. Magnetic resonance imaging scans typically show a cystic intrasellar lesion with suprasellar extension, containing isointense or, more often, hyperintense fluid on T1-weighted sequences. In spite of the risk of CSF fistulae, the preferred surgical approach is transsphenoidal. A physiopathological mechanism is proposed according to anatomic variations of the sellar diaphragma allowing penetration of subarachnoid spaces into the sellar compartment and their enlargement by a ball-valve mechanism.

We retrospectively analyzed 32 cases of primary central nervous system lymphoma (PCNSL). Five cases were diagnosed in the period 1987-1994, for 27 cases in the period 1995-2002. There were 17 men and 15 women whose median age was 69 years. Three patients were immunodeficient. The commonest symptoms were focal deficit (16 patients) and cognitive/behaviour disturbances (14 patients). Radiologically, a total of 47 contrast-enhancing lesions were observed in 32 patients; 18 patients had deep-seated lesions. All but two patients underwent histological diagnosis following craniotomy (11 patients) and/or stereotaxic biopsy (22 patients); diagnosis was obtained on CSF cytology in one patient with a third ventricle tumour. In the last patient, the diagnosis was based on the finding of marked tumour shrinkage under corticotherapy, despite two negative histological examinations. Treatment included surgical resection (10 patients), chemotherapy (25 patients) and/or radiotherapy (12 patients). According to the therapeutic recommendations of the GELA (Groupe d'Etude des Lymphomes de l'Adulte), 19 patients received at least two courses of high-dose methotrexate; intrathecal chemotherapy was used in 20 patients with methotrexate and/or cytosine arabinoside. Radiation therapy consisted of whole brain irradiation followed by a boost on tumour site. Nine patients received a combined treatment of chemotherapy and radiotherapy. Twelve patients showed rapid progression to death. At the time of last contact, 28/32 patients (88%) had died, all from PCNSL disease or from complications due to its treatment. The median Survival time was 13.9 months. We conclude that PCNSL is an increasingly frequent tumour. The diagnosis is obtained by stereotactic biopsy in the majority of cases. The prognosis appears dismal despite an intensive multidisciplinary therapeutic approach. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

Thoracic outlet syndrome (TOS) is due to compression/irritation of brachial plexus elements ("neurogenic TOS") and/or subclavian vessels ("vascular TOS") in their passage from the cervical area toward the axilla. The usual site of entrapment is the interscalenic triangle. TOS is a highly controversial subject in regard to its incidence, diagnostic criteria and optimal treatment. Constitutional factors--osseous or more often fibromuscular--and external factors such as trauma predispose to the development of TOS. Various clinical pictures include pain in the cervical region and arm, paresthesias, aggravated by overhead positions of the arms, hand intrinsic muscle deficit/atrophy, easy fatiguability, paleness, coldness of hand. The clinical examination may be entirely normal or show cervical and scapular muscle spasm, tenderness of supraclavicular area, radial pulse attenuation upon positional maneuvers, sensory and/or motor deficit, usually of C8/T1 distribution. The diagnosis is based on clinical evaluation and absence of other relevant pathology. Sometimes TOS can enhance symptoms consecutive to cervical or supraclavicular lesions. Cervical spine and distal peripheral nerves are investigated by radiological and electrophysiological studies. Unless there is significant motor deficit or subclavian artery compression, the treatment should be kept conservative as long as possible, by adapted physical therapy. In case of neurological deficit or symptoms unresponsive to medical treatment, the patients will--like in other nerve entrapment syndromes--be helped by decompressive surgery, nowadays preferably performed via an anterior supraclavicular approach.

This study analyses the interest of isologous venous grafts filled with saline or with Schwann cells versus nerve grafts as guides for regeneration of the sciatic nerve in 35 Wistar rats. Electrophysiological parameters (conduction velocities and distal latencies of motor responses) and the functional index of De Medinacelli were measured several times from 1 month to 1 year after surgery. An histological analysis was performed on 2 control rats and on 3 rats killed 6 or 12 months after surgery: the total number of fibers was counted on a montage photoprint of the whole nerve, and the diameters of axons and the thickness of the myelin sheath were measured on digitized images. With a portion of nerve as guide, the regeneration is faster than with a vein. However, regeneration after 6 months is at least as good with a venous graft filled with Schwann cells, as assessed by electrophysiological, functional, and histological analysis. The addition of Schwann cells in grafted veins allows the nerve to regenerate through longer gaps than previously described (25 vs 15 mm). In order to assess the quality of nerve regeneration, functional, electrophysiological, and histological analysis are complementary. [less ▲]
