SummaryA 1.6 kg, six-week-old Tibetan Terrier was admitted with a 12-hours history of acute onset of progressive tetraparesis following insertion of a microchip to the dorsal cervical region. Neurological examination indicated a lesion to the Ce1 to Ce5 spinal cord segments. Radiographic examination confirmed the intra-spinal location of a microchip foreign body at the level of the second cervical vertebra. Microchip removal was achieved following dorsal hemi-laminectomy; significant intra-operative haemorrhage was encountered. The puppy was ambulatory at day seven. Follow-up telephone interview 18 months postoperatively confirmed that the patient had made a good recovery although it had a mild residual right- sided torticollis.

Cervical Spine Myelopathy

     A Civilian gunshot wound associated with metallosis in the cervical spine region was an extremely rare case; hence, the clinician had difficulty with diagnosis and surgical treatment.      A 57–year-old gentleman had a history of a gunshot wound injury going back 30 years. He presented with neck pain, progress of paresthesia of upper extremities and progressively difficult ambulation for 3 months. Radiographic and pathological diagnosis from tissue of the 7th paravertebral of the cervical spine showed foreign bodies consistent with metallosis. The patient showed improvement of symptoms after posterior cervical spine fixation and decompression. He had full recovery at 1 year follow up.      Metallosis can occur in cases of chronic exposure to lead and metals. The results of this chronic process of metallosis will develop to metalloma, which then compresses the spinal cord and develops into myelopathy. The patient had a bullet, or piece of metal at the cervical spine, so surgical removal was performed to prevent further compression of the spinal cord from metalloma.

Objective: To report a case of young male with stroke and bilateral internal carotid artery (ICA) dissection. Background: Cervical Artery Dissection in Stroke Study trial has provided some insight on management of patients with ICA dissection. However, there is a need to modify the management strategies as per specific clinical scenario. Design/Methods: Case report and literature review. Results: A 45-year-old male presented with 1 month old history of acute onset numbness of right half of the body with slurring of speech. Computed tomography angiography showed complete occlusion of left cervical ICA just beyond origin with presence of fusiform dilatation and spiral flap in right extracranial cervical ICA. The patient was started on antiplatelets and taken for endovascular procedure using 2-mesh-based carotid stents. Patient was discharged after 3 days on antiplatelet therapy. At 1-year follow-up, there were no fresh symptoms. Conclusion: This case emphasizes the role of successful endovascular management of carotid dissection in a young male. These clinical situations may not be fully represented in trials, and a case-based approach is required.

Abstract Background To explore central nervous system (CNS) involvement in this disease, from the perspectives of diagnosis, treatment, and misdiagnosis Methods Twenty-eight patients with CNS echinococcosis were included in this retrospective study, including 18 males (64.3%) and 10 (35.7%) females. The average age of all the patients were 23.5 years (ranged 4–60 years). Twenty-three (23) patients (82.1%) received the first surgical resection in our hospital. Five (5) patients (17.9%) gave up surgical treatment for multiple-organ hydatidosis and previous surgery history at other hospitals, and albendazole was applied for a long-term (3–6 months) adjunct therapy for the 5 patients. The average follow-up time was 8 years. Results For the 28 patients, 23 cases received surgical treatments, and the diagnosis was confirmed by pathological examinations. The diagnosis of 4 cases of brain echinococcosis and 2 cases of spinal cord echinococcosis could not be confirmed, resulting in a misdiagnosis rate of 21.4% (6/28). For the pathological examination, a total of 17 cases were infected with Echinococcus granulosus (including 2 cases of spinal cord echinococcosis), and 6 cases were infected with Echinococcus alveolaris. Conclusion The diagnosis should be specifically considered in endemic regions. The clinical features of CNS hydatidosis were intracranial space-occupying lesions. For the treatment, the surgical removal of cysts should be necessary. In addition, the adjuvant therapy with drug and intraoperative prophylaxis is also suggested. The misdiagnosis may have resulted from atypical clinical features and radiographic manifestations, as well as the accuracy of hydatid immunologic test.

Abstract BACKGROUND: Reports of cervical perimedullary arteriovenous shunt (PMAVS) are limited, and treatment strategies have not been established. OBJECTIVE: To describe angioarchitecture and optimal treatment strategies for cervical PMAVS. METHODS: We treated 22 patients with cervical PMAVS between 2000 and 2012 (8 women and 14 men; age, 9-80 years). According to the classification, our patients included type IVa (4 patients), type IVb (16 patients), and type IVc (2 patients). Seventeen patients presented with subarachnoid hemorrhage. RESULTS: A total of 41 shunting points were localized in 22 patients, of which 34 points were located ventral or ventrolateral to the spinal cord. The anterior spinal artery (ASA) contributed to the shunts in 16 patients. Aneurysm formation was identified in 8 patients. Endovascular treatment was attempted in 3 patients, resulting in complete obliteration in 1 patient (type IVc). Overall, 21 patients underwent open surgery. An anterior approach with corpectomy was elected for 2 patients; the other 19 patients underwent the posterior approaches using indocyanine green videoangiography, intraoperative angiography, endoscopy (8 patients), and neuromonitoring. Twenty patients were rated as having a good recovery at 6 months after surgery. No recurrence was observed in any patients during the follow-up (mean, 59.7 months). CONCLUSION: Shunting points of the cervical PMAVS were predominantly located ventral or ventrolateral to the spinal cord and were often fed by the ASA. Even for ventral lesions, posterior exposure assisted with neuromonitoring and endoscopy, and intraoperative angiography provided a view sufficient to understand the relationships between the shunts and the ASA and contributed to good surgical outcomes.

Rathke's Cleft

Rathke's cleft cysts (RCCs) are benign cysts typically located in the sellar or suprasellar region; ectopic isolated lesions are extremely rare. The authors describe the case of a 25-year-old man with a giant symptomatic RCC arising primarily at the cerebellopontine angle (CPA), only the second case reported thus far. The patient presented with a 2-year history of right hearing impairment and tinnitus accompanied by vertigo and headache and a 2-week history of right facial numbness. Subsequently, he underwent total cyst removal via retrosigmoid craniotomy with a good recovery. He experienced no recurrence during a 64-month follow-up period. The possible pathogenesis, differential diagnosis, and surgical treatment of such cysts are discussed in this article. Isolated ectopic RCCs can arise from the ectopic migration of Rathke's pouch cells during the embryonic period. It is still difficult to distinguish ectopic RCCs from other cystic lesions of the CPA given the lack of specific imaging features. Aggressive resection of the cyst wall is not recommended, except when lesions do not closely adhere to adjacent structures.

Cysticercosis is an endemic condition in many developing countries. Although it is the most common parasitic disease of the central nervous system, cysticercal involvement of the spinal cord is rare. It may occur as intradural extramedullary, intramedullary, intramedullary associated with intradural-extramedullary or as the vertebral presentation. We report the case of a 53-year-old woman who presented with low back pain of acute onset and no other symptoms. Magnetic resonance imaging (MRI) showed an intramedullary cyst of the conus medullaris region which, at pathological examination, was diagnosed as a cysticercal cyst. She refused anticysticercal agents and steroids postoperatively. After an eight-year follow-up, the patient performs the activities of her daily living with no difficulties, and annual spinal MRIs show no residual signs of the disease. Clinical, pathofisiological, diagnostic and therapeutic aspects of spinal cord intramedullary cysticercosis are discussed.

Subtotal Removal

A series of nine cases of intradural spinal lipomas presenting in childhood or infancy are discussed. In all instances, associated congenital defects and a history of insidious neurological deficit were characteristic findings. In seven of the nine cases a subtotal removal of the intradural lipoma was accomplished, with resulting improvement in the neurological condition. In all instances the pathological interpretation of the lesion was that of an adult type of lipoma. Despite the benign connotations of lipoma, total surgical removal of these lipomas occurring intradurally has often been found not feasible and is probably not necessary. The inclusion of lipoma tissue within the substance of the spinal cord and nerve roots renders manipulation and excision extremely hazardous in terms of retaining the integrity of the nervous structures involved. In these instances subtotal surgical removal and decompression have proven beneficial in all instances in this series. Although exaggeration of neurological deficit may occur postoperatively, if the above surgical principles are adhered to, this deficit is not necessarily of a permanent nature.

The hemolytic-uremic syndrome (HUS) was first described by Von Gasser et al.1 in 1955 as a syndrome of acute renal failure, hemolytic anemia, and thrombocytopenia in children. Follow-up studies on HUS have emphasized hypertension and uremia as late complications.2,3 A review of the literature has revealed no previously reported cases of persistent colitis and bowel stenosis after HUS. We present a child who continued to have intermittent intestinal obstruction and diarrhea until surgical removal of a segment of colon almost seven months after the onset of HUS. CASE REPORT A 26-month-old white boy who had no history of gastrointestinal disturbance had sudden onset of diarrhea with blood and mucus in the stool.

INTRODUCTION: In this study the authors review the outcomes of 22 patients with medically refractory epilepsy and slow growth brain tumors. OBJECTIVES: Evaluate the clinical, electrophysiological, operative, and histopathological features. PATIENTS AND RESULTS: The majority of the tumors were located in the temporal lobe (n = 20) and involved the cortical gray matter. The most frequent tumors were gangliogliomas (n = 9), astrocytomas grade I and II (n = 6), dysembryoplastic neuroepithelial tumors (n = 5) and ganglioneuroma (n = 2). The biological behavior of the tumors was strikingly indolent, as indicated by a long preoperative history of chronic seizures (mean, 14 years). Mean follow-up time after resection was 27 months, and according to Engel’s classification, 85% were seizure-free, 10% showed a reduction of seizure frequency of at least 90%, and 5% had reduction in seizure frequency at least 75%. CONCLUSION: The data indicate that neoplasms associated with pharmacoresistent epilepsy constitute a distinct clinicopathological group of tumors that arise in young patients, involve the cortex, and exhibit indolent biological behavior for many years. Complete surgical removal of these tumors, including the epileptogenic area, can achieve excellent seizure control.

Secondary Invasion

Infantile myofibromatosis, a rare mesenchymal disorder that develops in early childhood, is classified by the number of lesions that occur: solitary or multicentric. Involvement of the CNS is unusual in either type. Infantile myofibromatosis in the spine is exceptional, and most published cases represent a secondary invasion. Here, the authors report on an 8-month-old girl presenting with weakness below the ankle and an intraspinal mass extending from T-6 to the conus. The patient underwent only partial surgical removal of the lesion, and the pathology was confirmed as infantile myofibromatosis. After the operation, weakness in the lower extremities gradually improved; however, she could not walk at the time of the final follow-up. On follow-up MRI performed 19 months after the operation, the residual lesion remained unchanged with decreased enhancement.
