Lumbar disc herniation associated with scoliosis in a 15-year-old girl: case report

Intervertebral disc herniation is a rare condition in childhood and adolescence, although some cases have already been reported in the literature. We present the case of a 15 year-old-girl with low back pain and scoliosis. She had no previous history of trauma or collagen diseases. MRI showed L4-L5 and L5-S1 disc herniations and no further bone and structural changes. After two level discectomy, pain ceased and scoliosis improved, without further treatment. Based on her evolution and on what has already been reported in literature, we consider that scoliosis associated with disc herniation in young patients is most likely to be only an anthalgic position, not indicative of further structural changes.     

Moyamoya disease in early infancy: case report and literature review

Moyamoya disease is a progressive, occlusive, cerebrovascular arteriopathy, characterized by bilateral stenosis of the distal internal carotid arteries or branches, with the development of compensatory collateral vessels. It is infrequently reported during infancy. We describe a 2-month-old boy presenting with stroke secondary to moyamoya disease, successfully treated with revascularization surgery at age 3 months. To our knowledge, this report represents the youngest such patient. This case and a review of the literature regarding moyamoya disease during infancy suggest that these patients are at significant risk for further ischemic events and respond well to prompt revascularization surgery.     

Calcified disc herniation in childhood

Calcification of intervertebral discs is a rare occurrence in children. Although the etiology of the calcification remains uncertain, it is no related with degenerative diseases. The clinical picture is non specific with neck pain, muscle contractures and, sometimes, low-grade fever. These symptoms generally disappear spontaneously, and surgery rarely becomes necessary. In our review of the literature, we have found only seventeen cases requiring surgical management. Two of these children had been previously diagnosed with calcified intervertebral discs, but at the time no herniation had been ruled out with magnetic resonance imaging (MRI). We report the case of a girl who was diagnosed, when she was ten years old, with intervertebral idiopatic calcifications. Four years later she presented with radiculopathy caused by the posterolateral displacement of a calcified cervical disc, which required operative management. We think that this case supports the theory of Heinrich et al. that considers that the calcified hernia is a complication of a previous pathology, namely intervertebral calcification. Clinical and therapeutic aspects of this entity are discussed.     

Chronic uncal herniation secondary to posterior fossa shunting: case report and literature review

Introduction  

Chronic herniation syndromes other than tonsillar herniation are not well-recognized. Transtentorial uncal herniation in its chronic form has been reported in only few case reports (Horowitz et al., J Neuroimaging 12:78–79, 2002; Naidich et al., Radiology 158:431–434, 1986; Ng and Valiante, J Clin Neurosci 16:944, 2009; Ng and Valiante, J Clin Neurosci 16:984, 2009). We hereby illustrate a case with this rare finding, including MR imaging, and analyze this phenomenon.     

Intraradicular extruded disc herniation as a rare cause of failed back surgery - case report and review of the literature

We report an unusual case of intradural intraradicular lumbar disc herniation, in which an extruded fragment of disc was found within the sheath of the left S1 nerve root. Previous surgery of our patient in another medical centre was not beneficial. The diagnosis of intraradicular extruded disc herniation was made at the time of surgery during exploration of the L5-S1 disc space. Although magnetic resonance imaging is a useful diagnostic tool in all patients with lumbar disc herniation, preoperative correct diagnosis is usually difficult, as occurred in our patient. A careful observation of the root during surgery is indicated to detect such an anatomical abnormality, especially in cases with recurrent disc herniation.     

Idiopathic intervertebral disk calcification in childhood: a case report and review of literature

Purpose  

Pediatric idiopathic intervertebral disk calcification (PIIVDC) is an uncommon entity affecting the intervertebral disks and adjacent vertebral body and musculoligamentous structures. More than 300 cases have been reported so far, but knowledge of PIIVDC is still fragmentary. The purpose of the study was to summarize the demographic and clinical characteristics of PIIVDC, and consider its treatment and natural history.     

Spontaneous intracranial hypotension in childhood: a case report and review of the literature

Spontaneous intracranial hypotension results from 1 or more spontaneous spinal cerebrospinal fluid leaks, and generally presents with severe and persisting orthostatic headache. Diagnosis can be difficult as spontaneous intracranial hypotension is very rare in childhood and has a wide spectrum of clinical features and neuroimaging findings. Lumbar autologous epidural blood patch can be helpful for confirmation of diagnosis and symptom relief. We report a 15-year-old female with spontaneous intracranial hypotension who experienced immediate resolution of her symptoms following lumbar autologous epidural blood patch on 2 occasions, and review the literature on this well-recognized but probably underdiagnosed headache syndrome in childhood.     

Transoral resection of retro-odontoid disc sequestration: case report and review of the literature

A rare case of retro-odontoid disc sequestration causing significant cord compression and progressive neurological deterioration is presented. The clinical history, radiology, treatment and pathogenesis of the case are described, along with a review of the relevant literature.     

Lumbar disc herniation and tight hamstrings syndrome in adolescence

BACKGROUND: Lumbar intervertebral disc herniation is infrequently encountered in children and adolescents. Additional signs and symptoms such as postural deformities and abnormal gait accompany the classical findings of lumbar root irritation. These unusual signs have been described in the literature as "tight hamstrings syndrome". Waddling gait with flexed knees is considered as pathognomonic for this condition and may be masked by the signs of root irritation due to prolapsed intervertebral disc material. CASE REPORT AND DISCUSSION: We report an adolescent patient with lumbar disc herniation in whom gait abnormality and limitation of lumbar movements persisted after surgical intervention. A review of the literature on tight hamstrings is presented.     

Hemihydranencephaly: case report and literature review

Hydranencephaly is a severe brain condition characterized by complete or almost complete absence of cerebral cortex with preservation of meninges, basal ganglia, pons, medulla, cerebellum, and falx. It has been ascribed to different causes (infections, irradiations, fetal anoxia, medications, twin-twin transfusion), all leading to vascular disruption. Hemihydranencephaly is an extremely rare condition in which the vascular anomaly is unilateral. We report on a patient who was suspected to have hydrocephalus in utero; a brain magnetic resonance imaging scan showed left-sided hydranencephaly with preservation of basal ganglia. The patient developed signs of right hemiparesis but notably has only mild language delay. The available literature on hemihydranencephaly is reviewed.     

Ossified thoracic spinal meningioma in childhood: A case report and review of the literature

Spinal ossified meningiomas are extremely rare. This is a report of a study on a 15-year-old boy with thoracic spinal ossified meningioma. The meningioma was resected totally. Histopathological examination revealed a transitional meningioma (psammomatous+meningothelial). Immunohistochemically, Ki 67 antibody was applied but no positive staining was present. The surgical and pathological aspects of spinal ossified meningiomas were reviewed.     

Transcranial cerebellar herniation following craniotomy: Case report and literature review

To report a case of post-surgical encephalocele through craniotomy burr holes following the resection of a meningioma of the posterior fossa. A 49-year-old female presented in the emergency room with cephalea. The MRI showed a meningioma of the convexity of the posterior fossa. A resection was performed and the bone flap replaced. The patient recovered uneventfully and was discharged. After 30 days the patient consulted referring cephalea, vomiting and imbalance. Brain MRI revealed a trans-cranial cerebellar herniation through the craniotomy burr holes. An urgent surgery was performed to repair the encephalocele. Post-surgical brain MRI was performed and did not show complications.Post-surgical encephalocele is an uncommon complication after the resection of a posterior fossa lesion. To avoid this complication, it is recommended thorough dural and bony closure, particularly in the posterior fossa surgeries and in high-risk patients.     

Acquired neuromyotonia in childhood: case report and review

Recently characterized as an immune-mediated channelopaty, Isaacs' syndrome (also known as acquired neuromyotonia) was first described in 1961 in two men with persistent, generalized muscle stiffness, in addition to spontaneous, rapid discharges of motor-unit potentials on electromyography. In the peripheral nervous system, antibodies targeted to voltage-gated potassium channels induce hyperexcitability of motor axons, resulting in signs of muscle stiffness or of pseudomyotonia. A spontaneous burst of single motor-unit activity, and myokymic and neuromyotonic discharges, are the most characteristic features found in electromyography studies. This report describes Isaacs' syndrome in a child, in whom the diagnosis was made by clinical features of acquired, spontaneous muscle overactivity and typical electromyographic findings.     

Familial occurrence of intracranial aneurysms in childhood: a case report and review of the literature

This report describes three individuals belonging to one family, who were affected with ruptured intracranial aneurysms (IAs) at a rather young age, 4, 15 and 23 years respectively. Familial IAs at this young age have not been described before. The evidence for a developmental, eventually inherited origin of familial IA in childhood is discussed with reference to the low occurrence of non-familial IA in childhood, IA-features in non-familial cases (localisation, multiplicity, size) and the association with (other) congenital malformations in the 0-5 years group.     

腰椎小关节方向性与腰椎间盘突出症

背景：腰椎小关节及其对称性与腰椎间盘突出之间是否存在关系,文献报道争议很大。 目的：测量分析腰椎小关节方向性与腰椎间盘突出的关系。 方法：收集因腰腿痛行CT检查的169例患者,L4/5 腰椎间盘突出35例,L5/S1腰椎间盘突出67例,无间盘突出对照组67例。在CT终端机上选取L3~S1椎间隙的远侧椎体上终板层面,测量3个节段的腰椎小关节角。 结果与结论：① L4/5和L5/S1腰椎间盘突出组L3/4、L4/5、L5/S1每个节段腰椎小关节角左侧均大于右侧(P < 0.05);各组小关节前内侧角和后外侧角两侧相比差异均无显著性意义(P > 0.05)。②各节段腰椎小关节角、前内侧角、后外侧角3组之间比较没有显著性差异(P > 0.05)。③各组腰椎小关节角、后外侧角自L3/4至L5/S1节段均逐渐增大(P < 0.05);而前内侧角L4/5节段最大,L3/4节段最小(P < 0.05)。提示腰椎间盘突出与腰椎小关节角左右侧不相等有关;腰椎小关节角和后外侧角自L3/4至L5/S1逐渐更偏向冠状位,而内侧角在L4/5节段更偏冠状位,可能与腰椎管狭窄的发病有关。
