“…Les schwannomes sont en règle des tumeurs isolées de taille modérée et de croissance lente, palpables lorsqu'ils sont volumineux ou superficiels. Le délai d'apparition des premiers signes est généralement long; souvent plusieurs années [ 7 , 8 ]. Les douleurs à type de paresthésie sont souvent les premières et uniques manifestations [ 7 , 8 ] comme le cas de nos patients.…”

“…Le délai d'apparition des premiers signes est généralement long; souvent plusieurs années [ 7 , 8 ]. Les douleurs à type de paresthésie sont souvent les premières et uniques manifestations [ 7 , 8 ] comme le cas de nos patients. Les déficits sensitifs et moteurs objectifs sont rares en raison du caractère non infiltrant de la tumeur, ce qui explique que l'exploration électromyographique soit généralement normale.…”

Les tumeurs primitives des nerfs périphériques représentent 1 à 2% des tumeurs des tissus mous. Les schwannomes sont en règle des tumeurs isolées de taille modérée et de croissance lente. Il convient de distinguer le schwannomes bénin et le neurofibrome des tumeurs malignes survenant généralement au cours d'une maladie de Recklinghausen. L'IRM permet d'orienter le diagnostic en mettant en évidence une tumeur de même signal que le tissu musculaire. Le traitement idéal de ces tumeurs consiste en une énucléation chirurgicale avec dissection soigneuse des faisceaux nerveux avoisinants. Nous rapportons deux cas d'un schwannome bénin développé aux dépens du nerf grand sciatique.

“…Though there were differences in both groups, the distinction was of little clinical value 10. In addition, it is important to note that differentiation of SCTs of the TLJ from other conditions (such as IVDs) is difficult when based only on clinical features 4,5,7,13. Symptomatic similarities may cause diagnostic delays of four months to three years in conus and cauda equina tumors.…”

“…Early diagnosis is important for reducing surgical invasion and aiding adequate recovery from symptoms, but is often disturbed 3-5,12. More than half (61%) of the sample reported pain as the presenting symptom, with leg pain appearing more frequently than back pain in both groups.…”

PurposeA retrospective review of medical records and imaging studies. To investigate characteristic clinical features and surgical outcomes of spinal cord tumors (SCTs) of the thoracolumbar junction (TLJ). The spinal cord transitions to the cauda equina in the TLJ. The TLJ contains the upper and lower motor neurons of the spinal cord and cauda equina. As a result, the clinical features of lesions in the TLJ vary, and these anatomical characteristics may affect surgical outcome.Materials and MethodsPathological diagnosis, clinical features, neurological signs, and surgical outcomes were investigated in 76 patients surgically treated at our institute for SCTs arising from T11 to L2. The patients were divided into epiconus (T11-12, n = 18) and conus groups (L1-2, n = 58).ResultsPatients in the epiconus group had hyperactive deep tendon reflexes (DTRs), while those in the conus group had hypoactive DTRs (p < 0.05). Nine patients were misdiagnosed with intervertebral disc diseases (IVDs) before correct diagnoses were made. It was impossible to definitively determine the exact cause of symptoms in four patients who had both SCTs and IVDs.ConclusionAmong SCTs of the TLJ, the epiconus group displayed upper motor neuron syndrome and the conus group displayed lower motor neuron syndrome. SCTs of the TLJ were frequently misdiagnosed as IVDs due to symptomatic similarities. SCTs of the TLJ should be included in differential diagnosis of back and leg pain, and it is highly recommended that routine lumbar magnetic resonance imaging include the TLJ.
