Spinal MRI (spinal + mri)
Selected AbstractsParaplegia as the presenting manifestation of extramedullary megakaryoblastic transformation of previously undiagnosed chronic myelogenous leukemiaAMERICAN JOURNAL OF HEMATOLOGY, Issue 2 2007Barbara J. Bryant Abstract Extramedullary tumors, also known as granulocytic sarcomas (GS), occur most frequently in acute myelogenous leukemia (AML). They may signal the onset of the accelerated phase of chronic myelogenous leukemia (CML) or the blastic transformation of a myeloproliferative disorder. Occasionally, a GS may be the presenting sign of undiagnosed AML, and rarely the presenting sign of undiagnosed CML or aleukemic leukemia. Paraplegia due to a spinal cord GS is an extremely rare presentation of undiagnosed leukemia. This is the first case report of paraplegia as the presenting manifestation of extramedullary megakaryoblastic transformation of previously undiagnosed CML. A 53-year-old woman reported back pain for 6 days, rapidly progressing to paraplegia. Physical examination noted a large abdominal mass and flaccid paralysis in both lower extremities. Spinal MRI revealed a T4,T6 vertebral mass causing spinal stenosis and cord compression. Tumor debulking and laminectomy were performed emergently. The tumor consisted of noncohesive blast cells. The CBC revealed a leukocyte count of 238,300/,l and a differential consistent with CML. Reexamination of the patient found that the abdominal mass was a giant spleen. Further immunohistochemical studies of the tumor were consistent with extramedullary acute megakaryoblastic blast transformation of CML. Although extramedullary blast crises herald the accelerated phases in ,10% of CML cases, megakaryoblastic blast transformation of CML accounts for less than 3% of these cases. The combination of acute paraplegia and megakaryoblastic transformation in a previously undiagnosed patient with CML is extremely rare and may pose a diagnostic dilemma. Am. J.

[source] Peripheral nervous system involvement as presenting symptom of systemic B-cell lymphomaJOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 2 2004C Casellato Peripheral nervous system involvement has been reported in systemic B or T cell lymphoma and may result from intraneural localization of lymphoma resulting in meningo-radiculopathy or mononeuropathies, or manifest as a sensory-motor polyneuropathy sometimes mimicking chronic inflammatory demyelinating polyneuropathy. We report two patients with a previously unknown NHL presenting in both with a stepwise progressive asymmetric multiradiculoneuropathy initially misdiagnosed as inflammatory radiculopathy. A 58-year-old man presented with a 2 year history of stepwise progressive peroneal sensory loss, impotence, and lower limb painful asymmetric neuropathy. Lumbosacral MRI was normal. Electrophysiological studies were consistent with an axonal multiradiculoneuropathy while CSF examinations repeatedly showed increased protein levels (80,91 mg/dl) with slightly increased white cells (<10 mm3) but no malignant cell. The patient repeatedly failed to respond to steroids although he consistently deteriorated at their suspension. An MRI performed 2 years later when multiple cranial nerve palsies appeared showed bilateral T1 and T2 hyperintensities in the brain and cervical spinal cord. An extensive investigation for neoplasm was negative. The patient died from an intracranial hemorrhage during anticoagulant therapy for deep vein thrombosis. Autoptic studies revealed a widespread non-Hodgkin's type B lymphoma with massive systemic and neural involvement including cauda equina and spinal cord. A 54-year-old man presented with a 1 year history of impotence, urinary incontinence, progressive asymmetric painful distal sensorimotor impairment at four limbs and prominent weight loss. Four previous CSF examinations revealed increased protein levels (80,100 mg/dl), and slightly but inconsistently increased white cells (1,11/mm3) but no malinant cells. Steroids were repeatedly ineffective although the patient consistently deteriorated whenever steroids were discontinued. On admission electrophysiological studies showed an axonal asymmetric polyradiculoneuropathy. Brain and spinal MRI was normal while bone marrow biopsy and aspiration disclosed a B cell lymphoma. [source] ANTI-SULFATIDE IgM ANTIBODIES DETECTED IN A PATIENT DIAGNOSIS OF MOTOR NEURON DISEASEJOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 1 2002Article first published online: 11 MAR 200 D'Avino C., Del Corona A., Bacci A., Calabrese R., Siciliano G. Department of Neuroscience-Clinical Neurology-University of Pisa-Italy Case report. The patient, a 66-year-old man with a 5-year diagnosis of diabetes mellitus, in Sep. 2000 started complaining of language disturbances as rhinolalia. In Jan. 2001, because of generalized fatigue and difficulties in walking, he was hospitalized in Internal Medicine and a diagnosis of diabetic angiopathy and neuropathy was made. Since discharge patient clinical conditions gradually deteriorated and a neurological evaluation showed tongue atrophy, dysarthria, dysphagia, fasciculations in the four limbs, increased deep tendon reflexes with bilateral foot clonus and paraparetic spastic deambulation. He underwent spinal MRI that showed mild arthrosic abnormalities in cervical spinal cord and limb EMG that showed denervation spontaneous activity with neurogenic MUAP modifications, with normal sensory and motor conduction velocity. MEP showed bilateral pyramidal track involvement. A significantly increased anti-sulphatide IgM antibodies titer (1:32,000) in the serum was detected. The diagnosis at discharge was "probable motor neuron disease" and the patient is under riluzole therapy at the moment. Discussion. Anti-sulfatide IgM antibodies are currently associated with several subtypes of peripheral neuropathy. In most cases it is a chronic dysimmune sensory or sensorimotor neuropathy in which electrophysiological and morphological studies are usually con- sistent with a predominant demyelination frequently associated with prominent axonal loss. Although rare, an association between motor neuron disease and IgM anti-sulfatide has been described in a recent paper by Latov and coworkers that reviewed electrophysiologic, morphologic and laboratory data of 25 patients with elevated antisulfatide antibodies. It seems interesting to follow-up the clinical course of the patient, the response to therapy and its correlation to antibodies titer, while the opportunity of high dose IVIg therapy is under discussion at the moment. [source] High prevalence of restless legs syndrome in multiple sclerosisEUROPEAN JOURNAL OF NEUROLOGY, Issue 5 2007M. Manconi Despite the fact that multiple sclerosis (MS) patients often include leg restlessness as a sensory symptom, MS is not mentioned amongst symptomatic restless legs syndrome (RLS) forms. The aim of this study was to estimate RLS prevalence in a large population of MS patients, comparing clinical and MRI findings between patients with and without RLS. Each of the 156 MS patients (100 females, 56 males, mean age 40.7 ± 10.4) enrolled in a prospective study underwent a medical history interview, a neurological examination with the assessment of the Expanded Disability Status Scale (EDSS), and a structured questionnaire to verify the presence and features of RLS. Conventional brain,spinal MRIs of 99 subjects were also evaluated and compared between patients with and without RLS. Fifty-one subjects (32.7%) (mean age 43.8 ± 12.8) met the criteria for RLS. In a few patients (8.5%), the RLS preceded clinical MS onset, whilst in the remaining cases the RLS was followed by or was simultaneous with clinical MS onset. Comparing the RLS group with the group without RLS, no significant differences were found in MS duration, gender, and referred sleep habits. The primary progressive MS course was more represented in the RLS group, which also showed a higher EDSS score. RLS is a very common finding in MS patients and should be considered amongst the symptomatic RLS forms. RLS is also associated with higher disability. [source] |
