ABSTRACT

INTRODUCTION: Depressed skull fractures are common and frequent among neurosurgical diseases of whose danger stem from the associated intracranial lesions. The aims of this study were to describe the epidemiological characteristics of depressed skull fractures, to determine their etiology, to describe the clinical signs, to highlight the complications and sequelae and to evaluate care management. PATIENTS AND METHODS: It was a retrospective and descriptive study from January to December 2013 including 72 patients admitted to the neurosurgical department of the Gabriel Toure hospital. RESULTS: The frequency was 14.7% and the male to female ratio was 13.4. The peak frequency of these injuries occurred in the 16-to 25-year-old age group accounting for 38.9% of cases. Road traffic accidents were the most common causes of depressed skull fractures (59.7%). Neurosurgical treatment was performed in 25 (34.72%) patients and the most common surgical technique performed was the craniectomy in (64%). Infection of the wound was found in 15.3% and the mortality rate was 1.39%. CONCLUSIONS: Depressed skull fractures are a frequent neurosurgical disease in the Gabriel Touré hospital. Young people are most affected and road traffic accidents involving motorbikes are the main cause the fractures. The infection of the wound is a poor prognostic factor. Therefore, an early management is required to expect a good outcome.

ABSTRACT

INTRODUCTION: Lumbar stenosis is a disease caused by a conflict between the neural structures (spinal cord and nerve roots) and spinal structures (bones and ligaments). The objectives of this study were to highlight the frequency, the diagnosis and therapeutics options, and to evaluate the treatment outcomes. PATIENTS AND METHODS: It was a retrospective study from January 2012 to December 2012 including 24 patients admitted to the neurosurgical department of the Gabriel Touré Hospital. RESULTS: The frequency of lumbar stenosis was 6.19% of all neurosurgical diseases. The sex-ratio was 0.71. The age ranged from 28 to 81 years with an average of 52 years. The neurogenic claudication was found in 87.5%. The straight leg raising test was positive in 41.7% of cases. The most vertebras involved were L4 and L5. Lumbar disc herniation was associated in 70.83%. Degenerative lumbar stenosis was the most common form, found in 66.67% of cases. Surgical treatment was performed in 29.17% of cases. The outcome was good in 85.6% of cases. CONCLUSIONS: Lumbar stenosis is a prevalent disease that occurs typically occurs around 50 years of age. The diagnosis was confirmed by myelography and a post myelographic CT scan. Good outcomes are achieved with both surgical or medical treatments.


INTRODUCTION: Le canal lombaire étroit (C.L.E.) est une pathologie liée à un conflit entre le contenant (ostéo-discoligamentaire) et le contenu (moelle épinière et ses composantes). Les objectifs de ce travail étaient de déterminer la fréquence du CLE, de déterminer les méthodes de diagnostic et de traitement, d'évaluer les résultats du traitement. PATIENTS ET MÉTHODE: Il s'agissait d'une étude rétrospective portant sur 24 cas de canal lombaire étroit colligés entre le 1er Janvier 2012 et le 31 Décembre 2012% dans le service de Neurochirurgie du C.H.U Gabriel Touré. RÉSULTATS: le CLE constitue 6,19% de nos patients opérés. Le sexe féminin prédominait avec 58%. L'âge moyen était 52 ans avec les extrêmes de 28 ans et de 81 ans. La claudication était retrouvée à l'interrogatoire chez 87,5% des cas. le signe de Sonnette était retrouvé chez 41,7% des patients. Les vertèbres L4 et L5 étaient les plus touchés. La hernie discale était associée dans 70 .83%. Le CLE acquis représentait 66,67% des cas, la forme constitutionnelle,25% et celle congénitale, 8,33%. Le traitement a été médical dans 70,83% des cas et chirurgical 29,17%. Les résultats étaient bons dans 85,6%. CONCLUSION: le CLE est une affection fréquente se manifestant vers l'âge de 50 ans. La confirmation du diagnostic était faite par la saccoradiculographie couplée au myéloscanner. Le traitement médical ou chirurgical donne des bons résultats.

ABSTRACT

INTRODUCTION: The cervical disc hernia is uncommon. Its diagnosis is usually easy. But his surgery known controversy between discectomy with or without graft associated or not osteosynthesis. Accordingly we report our experiment of this surgery through a small serie of 9 patients operated by anterior approach. MATERIALS AND METHODS: This was a retrospective study of nine (9) patients supported by an anterior cervical disk herniation between 2001 and 2006 at the General Hospital of Grand Yoff in Dakar. The diagnosis was made on clinical and cervical myéloscanner. The postoperative decline was between 1 and 5 years. RESULTS: The average age of patients was 43 years ranging from 20-68 years. A male prevalence (2/1) was noted. The majority of hernias was degenerative. It was mostly soft disc hernia that prevailed on floors C4-C5 and C5-C6. We always operated on the right side of the patient. We performed a discectomy of a floor in 8 cases and 2 floors in 1 case. The vertebral posterior longitudinal ligament was opened routinely. Graft with osteosynthesis was used in 4 cases. The outcome was good. A spontaneous fusion was noted in 7 cases. CONCLUSION: The surgical treatment of cervical disc hernia is usually anterior approach. It is usually associated with good postoperative results.


INTRODUCTION: La hernie discale cervicale est une pathologie peu fréquente. Son diagnostic est en général facile. Cependant sa prise en charge connaît des controverses entre discectomie avec ou sans greffe associée ou non à une ostéosynthèse. Dans cette optique nous rapportons notre expérience de cette chirurgie à travers une petite série de 9 patients opérés par voie antérieure pré-sterno-cléido-mastoïdienne. MATÉRIEL ET MÉTHODES: Il s'agissait d'une étude rétrospective portant sur 9 patients pris en charge par voie antérieure pour hernie discale cervicale entre 2001 et 2006 à l'Hôpital Général de Grand Yoff de Dakar. Le diagnostic avait été fait sur la clinique et le Myelo-scanner cervical. Le recul post-opératoire était compris entre 1 et 5 ans. RÉSULTATS: L'âge moyen des patients était de 43 ans avec des extrêmes de 20 à 68 ans. On notait une prédominance masculine (sexe ratio de 2/1). La majorité des hernies était d'origine dégénérative. Il s'agissait essentiellement des hernies discales molles qui prédominaient aux étages C4-C5 et C5-C6. Tous les patients ont été opérés par la droite. Nous avons réalisé une discectomie d'un étage dans 8 cas et de 2 étages dans 1 cas. Le ligament longitudinal vertébral postérieur était ouvert systématiquement. Une greffe avec ostéosynthèse a été utilisée dans 4 cas. L'évolution a été bonne. Une arthrodèse spontanée a été notée dans 7 cas. CONCLUSION: Le traitement chirurgical de la hernie discale se fait généralement par voie antérieure. Il est généralement associé à de bons résultats post-opératoires.

ABSTRACT

Human schistosomiasis is the second endemic disease after malaria. About 200 millions people are concerned, particularly in Africa, South America and Asia. Schistosomal spinal cord compression is under reported in Africa and not well known. Authors present the case of a 10-year-old boy with no suggestive past-medical story, admitted for spinal cord compression. MRI shows tumor like intra dural lesion. Schistosomal granuloma was found after lesion removal by posterior approach. Treatment was completed by praziquantel. Controversies of the treatment are presented.

ABSTRACT

From January 2005 to December 2009, 20 patients have been treated for bilateral chronic subdural hematoma at the Grand Yoff General Hospital in Dakar, Senegal. This was a retrospective study concerning clinical, imaging, and therapeutic issues faced and comparing them to unilateral chronic subdural hematoma issues recorded during the same time period.Median age was 71 years old, ranging from 35 to 95 years old. 17 patients were male and were 3 female. Previous head trauma had been reported for 55% of the patients, high blood pressure - associated or not with diabetes mellitus - had been recorded in 45% of the patients.Clinical symptoms were marked by high intracranial pressure and motor deficits in 70% of cases and 40% showed a mental confusion.Brain CT scans were the key diagnostic tools; all patients undertook a scan and results demonstrated blood subdural collection with variable density in the right brain hemisphere (in 30% of cases).The focus of the surgical treatment was a bilateral burr hole, evacuation of the hematoma and no more than 3 days of postoperative drainage. The medical treatment consisted of an adapted hydro-electrolytic rehydration. The outcome of treatment was positive for 17 patients (85%), 2 patients suffered from subsequent hematoma and 1 patients passed away.


Nous rapportons une série rétrospective de 20 cas consécutifs d'hématomes sous-duraux bilatéraux recensés de Janvier 2005 à Décembre 2009 à l'Hôpital Général de Grand Yoff (HOGGY) de Dakar.Nous avons étudié les aspects étiologiques, cliniques, radiologiques, thérapeutiques et évolutifs et nous les avons comparés aux formes unilatérales recueillies pendant la même période.L'âge moyen de nos patients est de 71 ans avec des extrêmes de 37 à 95 ans, nous avons retrouvé 17 hommes soit 85% pour 3 femmes soit 15%.Les antécédents de traumatismes crânio-encéphaliques (TCE) ont été retrouvés dans 55% des cas, les antécédents d'hypertension artérielle (HTA) et/ou Diabète ont été retrouvés dans 45% des cas.Les signes cliniques sont marqués par l'hypertension intracrânienne dans 70% des cas, des troubles moteurs à type d'hémiparésie surtout dans 70% des cas, des troubles confusionnels dans 40% des cas.La Tomodensitométrie (TDM ou Scanner) a constitué la clef de voûte du diagnostic, elle a été pratiquée dans 100% des cas; elle a mis en évidence l'hématome avec une légère prédominance volumétrique à droite (30 %).Le traitement chirurgical a consisté en une tréphination ou une trépanation élargie à la gouge avec mise en place d'un drain de chaque côté dont la durée n'excède pas dans tous les cas 72 heures.Le traitement médical a consisté en une réhydratation hydro électrolytique adaptée.L'évolution a été favorable chez 17 patients (85 %); On note cependant deux (2) cas de récidive et un (1) décès.

ABSTRACT

The cerebral tuberculoma is an expansive process of slow evolution of the tuberculous bacillus. Bacteriological diagnosis is rarely made. It is usually radiological or histological. The treatment is medical and surgical. We conducted a retrospective study from March 2007 to February 2010 which focused on three cases of cerebral tuberculoma. Two of our patients were male, 75% against 25% female: The age of our three patients was respectively 47, 23, and 4 years. The history of extrapulmonary tuberculosis was found in one case. The heaviness of the head was the pattern in a patient operated on for Pott's disease. The diagnosis was suspected by neuroradiology in 3 patients and histological confirmation was made in 2 cases. The polychimiotherapy of 12 months was established and the improvement has been obtained from the third month of treatment.

ABSTRACT

Nous rapportons ainsi une serie retrospective de 88 cas de patients porteurs d'hematomes sous-duraux chroniques recenses de Janvier 2000 a Decembre 2005 a l'hopital general de grand Yoff (HOGGY). Nous nous sommes proposes d'etudier les particularites cliniques; diagnostiques; therapeutiques et evolutives a l'ere du scanner. L'age moyen est de 67ans avec des extremes de 23 a 95 ans. Nous avons note 77 hommes soit 87;5pour 11 femmes soit 12;5. Les antecedents de traumatismes cranio-encephaliques (TCE) ont ete retrouves dans 56;91des cas; ceux d'hypertension arterielle et/ou diabete ont ete notes dans 40; 85des cas. Nous n'avons pas retrouve de notion d' ethylisme chronique avoue par nos patients La symptomatologie clinique etait dominee par le syndrome deficitaire moteur dans 77;64des cas; les troubles psychiatriques a type de desorientation temporo-spatiale; d'amnesie; de delire onirique rencontres dans 40;58des cas; les formes pseudo-tumorales avec hypertension intracranienne (HIC) suivie ou non de baisse de l'acuite visuelle (BAV) dans 59;26des cas. Le diagnostic d'hematome sous-dural chronique (HSDC) a ete etabli par la tomodensitometrie (TDM). Cet examen retrouve 68 cas d'HSDC unilateral soit 72;27et 20 cas d'HSDC bilateral soit 27;72. Le traitement chirurgical a consiste en une vidange de la collection apres trepanation suivie d'un drainage n'excedant pas 72 heures. La rehydratation hydro electrolytique abondante a constitue le traitement medical. Sur le plan evolutif; nous notons une mortalite de 3;97et un taux de recidive a 10. L'HSDC est une affection geriatrique frequente mais tres peu connue en medecine omnipraticienne. Le traitement chirurgical est simple. Son evolution souvent benigne pourrait etre greffee d'une morbimortalite appreciable en l'absence d'un diagnostic precoce

ABSTRACT

The posterior cerebral fossa is an uncommon location for cerebral abscess. In most cases diagnosis is made at the encapsulation stage with the risk of life-threatening tonsillar herniation. The purpose of this retrospective study was to describe our experience in the management of four cases of abscess located in the posterior cerebral fossa between January 2000 and December 2004. All patients benefited from clinical examination and radiological study (CT-scan). Surgical treatment performed in all cases consisted of trepano-puncture of the abscess. The minimum duration of post-operative follow-up was 6 months. Mean patient age was 38.75 years. All patients presented infectious syndrome and intracranial hypertension. The male:female sex ratio was 3:1. A history of chronic middle ear otitis was noted in two patients. Diagnosis of abscess in the posterior cerebral fossa was confirmed by CT-scan in 2 cases. Cholesteatoma and triventricular hydrocephaly were noted in 2 cases. All patients benefited from trepano-puncture of the abscess. Bacteriologic study of pus was positive for Staphylococcus aureus in 1 case, and Providencia Sp associated with Bactéroïdes fragilis in another. Second-stage radical mastoidectomy was performed in 2 cases. One patient died. The outcome was favorable in 3 cases. Because of the small size of the posterior cerebral fossa, abscess in that location requires emergency treatment. Delay can be life-threatening due to the risk of obstructive hydrocephaly and tonsillar herniation.

ABSTRACT

The encephaloceles belong to dysraphic state abnormalities. Publications on this issue are rare and sparse in Africa. The aim of our study is to describe clinical patterns of occipital encephaloceles, and emphasize on surgery. We collect retrospectively a population of 16 patients. Cranial Ultrasound Echographia has been done for all of them. Only 3 patients got brain CT scan. Medium age was 2 months. The sex ratio was coted 1. The consanguinity was noted in 37% of the cases. The pedicular aspects were more frequent. With neuroimaging studies the diagnosis was reached everytime. It showed hydrocephalus on 3 patients. 15 patients have been operated. One dead before going to surgery. The outcome was good for 13 patients (81%). But 3 patients (18%) deaded, and among them, 2 deaded during post surgery period. A better clinical evaluation showed be done using MRI. The control of epidemiology of these conditions depend on the improvement of the quality of eating in particularly in women bearing child, and performing a genetic counseling.

ABSTRACT

Mycetomas inflammatory-like tumors presenting as fistulas found in the skin and soft tissues. Inoculation, generally in tropical areas, occurs by skin injury. The foot is the main infection site. Other uncommon infection sites include the cranial and cervical areas which are rare. We present three cases of cranial and cervical mycetoma. Clinical sign were dominated by headache, cervical pain and cervico-occipital tumefaction with formation of pus and granules (red in two cases, black in one). A motor deficit was noted in one patient. Radiographic examinations including CT scan showed extensive mass lesions, associated with bone destruction. Laboratory tests identified Leptospheria senegalensis in one patient and Actinomadura pelletieri in two. A medicosurgical procedure was performed. The course was unfavourable in one patient. Several factors are important for treating such infections: early diagnosis, improvement of the social and economic environment, use of new drugs.

ABSTRACT

Introduction : L'hématome sous dural est une complication observée lors du traitement chirurgical de l'hydrocéphalie. Avant l'avènement de la tomodensitométrie à Dakar, une incidence de 0,8 % était trouvée. L'objectif de notre travail est de réévaluer cette incidence à la lumière de cet examen et de déterminer les divers facteurs étiologiques. Patients et Méthode : Nos patients ont été opérés par dérivation ventriculo-péritonéale et sont âgés de 8 à 30 ans au moment du diagnostic. Quatre sont de sexe féminin. Le signe le plus fréquent est l'hypertension intra-cranienne. La tomodensitométrie a établi le diagnostic dans tous les cas. Elle montrait dans 4 cas, un hématome unilatéral et dans deux cas, une forme bilatérale. D'importantes calcifications sont retrouvées dans deux cas. Cinq patients ont été opérés et nous notons deux décès. Les valves utilisées sont à débit de drainage fixe. Résultat : Il existe une augmentation de l'incidence par rapport à notre première série datant de 12 ans. Par rapport aux autres systèmes de drainage, nous ne notons pas de différence significative. Aucun facteur étiologique déterminant n'est retrouvé. Conclusion Cette complication pouvant pauci-symptomatique, la réalisation d'examens tomodensitométriques systématiques permettrait de constater une plus grande fréquence de cette complication

ABSTRACT

Meningioma is an uncommon tumor of childhood. In this group, supra tentorial forms predominate. We report the case of a 14 years old boy without any past medical history. He presented headaches, vomiting and cerebellar syndrome. CT scan shows cerebellar tumor, enhanced by contrast and surrounded by edema, looking like tuberculoma. After fail of tuberculosis treatment, the boy is operated by suboccipital approach. Histology and immuno histochemical examination show fibroblastic meningioma. Even if it is rare, meningioma can occur in childhood, without neurofibromatosis disease. It can present many points of likeness with tuberculoma and therefore biopsy is mandatory before tuberculosis drugs giving.

ABSTRACT

In our regions malaria is endemic and intraguteal injection is a common procedure. One unfortunate complication of that procedure appeared to be a sciatic nerve injury. The purpose of our study was to set up the anatomical feature and basis of this post injection lesion. We performed sciatic nerve gluteal dissection on 10 adults black African fresh cadavers on both side. The pathway of the nerve was 19 times in the subpiriformis canal. Only in one cadaver, the outlet of the nerve was above the piriformis muscle. In each case the pathway is identical with an oblique and vertical portion running down through the ischio-trochanteric channel. The nerve was crossed between its two portions by an arteriole coming from the inferior gluteal artery. The cutaneous projection of the sciatic nerve is distant from the upper lateral quadrant of the buttock. Intra-gluteal injections in this area doesn't damage the nerve. The anatomical variations of this nerve pathway are almost nonexistent. So, other hypothesis of sciatic nerve post injection lesion should be considered. We think that the local toxicity of quinine and its diffusion in the neurovascular gluteal area might explain the nerve lesion. Thus, the intramuscular injections should be replaced by the intravenous or rectal administration in children.

ABSTRACT

A retrospective study of 9 cases of fronto-ethmoïdal encephaloceles is reported. Cases have been gathered from the files of Dakar University Neurosurgical Unit. Fronto-ethmoïdal encephaloceles were about 9.8% of all encephaloceles. In all the cases the exit hole from the anterior cranial fossa is at the site of the foramen caecum. The location of the tumor was fronto-nasal in seven patients and naso-ethmoïdal in two. The cranio-facial deformity consisted of increase of local volume and a lateral displacement of medial canthus in six cases, a down ward drift of the tip of the nose in two cases and one case of orbital hypertelorism. Eight cases were meningo-encephaloceles and the last a meningo-encephocystocele. Diola was the most ethnic group involved. All patients have been operated by a simple neurosurgical procedure without obstruction of the cranial defect nor bony displacement. In five cases mental and aesthetic results were good when operation was done during the first year of live. The authors stress early surgical treatment for fronto-ethmoïdal encephaloceles.

ABSTRACT

Arachnoïd cysts are rare. 1% of cranial neoformation. We report the case of a six years old boy who presented an arachnoid cyst impressive by its compressive phenomena. Present complaint are macrocrania and right orbitary tumor. Tomodensitometry reveal a huge liquid collection which starts from the right cerebellopontine angle to the frontal region and invading the orbital cavity. In addition we have a thalamic fusion Its congenital origin is obvious. The associated malformations seem to be related to an anomaly of the centre line. This case point out the primum movens of malformations which are often complex and whose antenatal diagnosis is rare in our countries
