[Syphilitic spinal cord gumma].

Syphilitic spinal cord gumma Syphilitic gummas of the central nervous system are exceptional and are in general described in the brain. We report the case of a Brown-Sequard syndrome in a 25-year-old patient. The cervical myelography and the brain CT as well as the vertebro-occipital junction were normal. The diagnosis of multiple sclerosis was evoked and corticosteroid therapy was initiated. The patient experienced clinical improvement. Two years later, the patient was readmitted. Immunological reactions for syphilis were positive, in serum and CSF. Tests for HIV were negative. The MRI showed a cervical spinal cord process at the C3 level with adhesive spinal associated arachnoiditis. Penicillin therapy was started prior to surgery for the spinal process. The syphilitic nature was confirmed by pathology. To our knowledge, the MR appearance of a syphilitic gumma of the spinal cord has not been described previously in the scientific literature.

[Contribution of spiral CT scan and MRI in spinal tuberculosis].

Spinal tuberculosis is the most frequent skeletal involvement in tuberculosis. The purpose of this study was to demonstrate the importance of the MRI and the helicoidal CT scan in the diagnosis of spinal tuberculosis. A retrospective study was conducted in 23 patients with spinal tuberculosis. The methods of investigation were helicoidal CT scan in 15 patients and MRI in the other eight patients. In the all cases with helicoidal CT scan, the features of the spinal tuberculosis were seen as an anterior vertebral body destruction with a paraspinal or epidural extension in 12 cases and a sequestrum formation in 5 cases. The analysis with helicoidal CT scan showed a gibbous deformity in 5 cases, a disk space narrowing in 14 cases and evaluated the extension very well. The MR imaging features showed one case in an early stage without features on the plain radiographs, and detected 3 cases of intramedullary lesions. A disruption of the longitudinal posterior vertebral ligament was found in one case and skip lesions at the granulomatous stage in 2 cases. MRI is superior to CT scan even helicoidal CT at the early lesion stage, skip lesions and the ligamentous or medullary lesions. For other lesions (bone, disk, extension), the MRI and CT scan are the same with an advantage for CT scan in osseous lesions.

[Dermoid cyst of the conus medullaris revealed by chronic urinary retention. Contribution of imaging].

We report a case of congenital dermoid cyst of the conus medullaris without associated dysraphic lesion treated surgically. An 18-year-old man had a one-year history of bladder sphincter disorders and more recent acute renal failure with urinary tract infection. The diagnosis of intramedullary tumor was provided by myelo CT and MRI confirmed by histology. At 10-month follow-up, the postoperative course was good.

[Vertebral body exocytosis and spinal cord compression].

Osteochondroma is a cartilaginous tumor, the most common benign tumor of bone. It may involve solitary or multiple exostoses (or osteochondromatosis) usually in hereditary multiple exostosis. The authors report a case of 13-year-old girl with a family history of hereditary multiples exostoses who presented with bilateral sciatica and cauda equina compression. The MRI showed a tumor of the L1 vertebral body. After surgery, pathologic specimens revealed the lesion to be an osteochondroma. Involvement of the vertebral column has been estimated from 1.3 to 4%. Spinal cord compression is rare. CT provides the analysis of the components of the tumor and clearly demonstrates it's intracanalar extension. MRI is superior in visualizing spinal cord compression. The prognosis is favorable after a surgical decompression.

[Primary osteosarcoma of the skull. Apropos of 2 cases].

Primary tumors of the skull are rare and are estimated approximately in about 2.4% of all bone primary tumors. Primary craniofacial osteosarcoma accounts for 2 to 9% of cases in published series. The pure cranial location are estimated in the range of 0.7 to 3%. Spreading lesions to the central nervous system is uncommon, in addition plain film features are misleading due to the lock of evidence of osseous involvement of the calvaria. CT scan is more sensitive to demonstrate bone lesion as well as brain extension. MRI depict the soft tissue components even more clearly. We report two cases of skull osteosarcoma in two female patients without any preexistent affection. The particularity of these observations is that the intracranial extension presented as the brain tumor.

[Neck-tongue syndrome: a case caused by atlanto-axial osteoarthritis of tuberculous origin].

The neck-tongue syndrome involves paroxystic pain in the nape of neck associated with sensitive disorders of the ipsilateral hemitongue aggravated by movements of the nape of neck. It is attributed to relating fibers of proprioceptive origin which pass through the great nervus hypoglossus from the second cervical stria. The lingual pseudoathetosis is also reported to a proprioceptive deafferentation of the tongue. In most of cases, no etiology has been found. We report a case of neck-tongue syndrome with pseudoathetosis, related to an atloaxoid osteoarthritis of tuberculous origin.

[A new treatment of osteoid osteoma: percutaneous sclerosis with ethanol under scanner guidance].

Osteoïd osteoma is a benign bone tumor, easy to diagnose because of its typical presentation. However, it may be difficult in some cases: peculiar locations (spine, femoral neck...), or lack of visibility during surgery. Numerous removal technics under CT guidance have been proposed during the last few years. We will suggest another therapeutic way to treat a case of osteoïd osteoma, located in the upper extremity of the femur. The complete removal of the nidus was not possible despite two surgical attempts. So, its percutaneous sclerosis under CT guidance was accomplished, allowing the disappearance of the pain without patient immobilization afterwards. We will compare this easy and reliable method to those already described in the literature.

[Cerebral vascular accidents due to hydatid embolisms. Apropos of 2 cases].

Hydatid cysts of the brain are very rare. Exceptionally, signs and symptoms are primarily those of acute cerebral ischaemia. Two cases of acute cerebral ischaemia are reported in a 21 year old and 40 year old women. A computed tomographic scan revealed a middle cerebral artery (MCA) infarct and an abrupt cutoff of the MCA at cerebral angiography. A few months later, a CT scan showed cysts in the territory of the infarct. Hydatid cysts were also found in multiple viscera, particularly in the heart. These two observations and some cases reported in the literature suggested that the myocardial cyst may have ruptured into the ventricular cavity, resulting in widespread intravascular dissemination of embryo and causing an acute cerebral infarction. The interest of these cases lies in the rarity of an acute cerebral ischaemia due to hydatid cyst embolism, and in the early diagnosis of cardiac cysts in young patients.

[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.

[Pure motor hemiplegia with ipsilateral lingual palsy caused by pontine infarction].

A 36 year old diabetic man developed a pure motor hemiplegia (PMH) associated with an ipsilateral lingual palsy. Magnetic resonance imaging revealed a pontine infarct. Lingual palsies have never been reported in patients with PMH so far, but may be associated with other lacunar syndromes such as the "dysarthria-clumsy hand syndrome". This observation supports the hypothesis that corticohypoglossal pathways may have bilateral and assymetrical projections.

[Spontaneous rupture of an intracerebral dermoid cyst].

Dermoid and epidermoid cysts are rare benign tumors arising from ectopic epiblastic inclusions. Dermoid cyst accounts for 0.4 to 1.5% of all tumors. We report the case of a 43-year-old man, who presented with a 6-month history of disturbances of balance and behavioral disorders. X-ray showed two fat-fluid levels in the ventricles. CT scan showed a left frontal mass with fat density, communicating with the left frontal horn. Histological examination after surgical excision confirmed the diagnosis of dermoid cyst. The diagnosis of ruptured intracranial dermoid cyst is based on the finding of an intraventricular and/or subarachnoid space fat-fluid level. MRI and CT scan facilitates the diagnosis of ruptured intracranial dermoid.

[Spinal aneurysmal cyst].

The authors report one case of aneurysmal rachidian cyst who concern a young girl of eleven years old presenting lumbagos with pyramidal irritation on a L2 and L3 lesion. The radiological exploration (CT, MRI) has a double interest: to find again lytical pictures of the rear arch blowing the cortical, liquids levels, logets which remind the macroscopical appearance of the aneurysmal rachidian cyst; to specify the regional extension of preoperative interest. The histological confirmation of the aneurysmal rachidian cyst after a surgical treatment and the conformity of anatomo-radiological descriptions, confirm the predictive value of the semeiology described in case of aneurysmal rachidian cyst.

[Alexia without agraphia in the Arabic language. Neurolinguistic and and MRI study].

A 33 year-old woman developed an alexia without agraphia, a color anomia, a right hemianopia, an aphasic amnesia and a verbal amnesia. The brain MRI showed the lesions in the left splenium of corpus callosum, forceps major, optic radiations and anterieur temporal lobe. The fact that she measured writing comprehension and had complete recovery of reading impairment despite the persistence of anatomic lesions plead in favour of an active participation of the right hemisphere (RH) on reading; this capacity of the RH may be due to the linguistic particularities of arabic writing.

[Thrombosis of the upper longitudinal sinus and syphilitic cranial osteitis].

A 33-year old man developed progressive intracranial hypertension with papilloedema due to thrombosis of the superior sagittal sinus (SSS) by extension of a skull osteitis. Serological tests for syphilis were positive in blood, CSF and synovial fluid. Under treatment with penicillin and corticosteroids signs of intracranial hypertension and CT scan abnormalities disappeared. SSS thrombosis persisted at angiographic control.
