Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic deficit. The cavernous hemangioma was resected through combined video-assisted thoracoscopy and laminectomy without a fusion procedure. The patient had tolerable operative wound pain with no neurologic deficit after surgery. Based on magnetic resonance imaging findings and a review of the literature, we discuss cavernous hemangioma among the differential diagnosis of paravertebral dumbbell-shaped spinal tumors and the importance of complete resection.

Intraspinal cavernous malformation (CM) accounts for 5% to 16% of all spinal vascular abnormalities. Multiple spinal cord CMs are very rare and only a few cases have been described. We report a patient presented with right chest paresthesia and seizure, and diagnosed as multiple spinal intramedullary CM and intracranial involvement.

Cavernous angiomas represent 5 to 12% of spinal vascular malformations and usually are located at the vertebral body level with possible extension into the extradural space. The intradural intramedullary cavernous angioma occurs in about 3% of cases, whereas extramedullary localization is extremely rare. We report a case of intradural extramedullary cavernous angioma in which the patient presented with low back pain and both leg pain. The magnetic resonance imaging study showed intraspinal mass lesion at L1-2. It was removed totally through laminectomy of L1-2 and confirmed as cavernous angioma. The postoperative course was uneventful without any neurologic deficit. We report this unusual spinal malformation.

A 45-year-old female visited our clinic due to sudden right leg weakness and sensory loss. Brain and spinal cord magnetic resonance imaging showed widespread cavernous malformations. Cavernous malformation in L1 spine area was accompanied by a subacute stage hematoma with perilesional edema. Sensory loss subsided after corticosteroid therapy. Usually, neurologic deficit by spinal cavernous malformation appears more chronically in the adults compared to children. Treatment options are difficult to establish in a case with multiple cavernous malformations. Identifying hemorrhagic lesions by extensive neuroimaging evaluation could be helpful to select the treatment target for cavernous malformation.

Cavernous angiomas are being increasingly well recognized throughout the central nervous system due to the widespread use of magnetic resonance imaging(MRI). However, these malformations are uncommon in the spinal column and rarely occur in the spinal cord. Here, we report a case of a cervical cord intramedullary cavernous angioma in a 49-year-old man. The patient had complained of left upper extremity paresthesia and weakness in the left hand for 5 days prior to admission. A neurological examination showed a left C-6 dermatome paresthesia and a weakness in the left hand grasping power. A MRI demonstrated a mixed signal intensity core at the C-5 level and a surrounding edema on the T-2 weighted image. Conservatively, a laminectomy was performed and slightly hard and well demarcated intramedullary mass was removed. A histological examination confirmed the diagnosis of a cavernous angioma.

Spinal cavernous hemangiomas of the cauda equina are extremely rare vascular malformations. We report a case of intradural extramedullary cavernous hemangioma of the cauda equina with it's clinical, radiologic and surgical findings. This is the twelveth case of cavernous hemangioma of the cauda equina in the literature. The pertinent literatures are reviewed.

A case of intradural extramedullary cavernous angioma is presented with headache, dizziness, and bilateral sensorineural hearing loss caused by an intracranial superficial hemosiderosis. It was incidentally found in a patient with a 3-month history of sustained headache, dizziness and a 3-year history of hearing difficulty. The neurological examination was unremarkable in the lower extremity. MR images showed an intracranial superficial hemosiderosis mostly in the cerebellar region. Myelography and MR images of the thoracolumbar spine revealed an intradural extramedullary mass, which was pathologically proven to be a cavernous angioma. T12 total laminoplastic laminotomy and total tumor removal were performed without any neurologic deficits. The patient's symptoms, including headache and dizziness, have been absent for three years. Intradural extramedullary cavernous angioma can present with an intracranial superficial hemosiderosis as a result of chronic subarachnoid hemorrhage.

Although cavernous angioma itself is not rare, the epidural spinal localization is uncommon and makes preoperative differential diagnosis difficult. An extraordinary case of a thoracic epidural cavernous angioma in very young age, causing sudden paraplegia is presented. Only 79 cases have been reported in the literatures and among them, this kid was the youngest. A 23-month-old boy was referred to us with a 2-day history of sudden both lower limb weakness. Two days before admission, he got up at morning and was unable to stand and even to move the legs. MRI revealed an epidural mass surrounding spinal cord associated with cord compression at the level of the C5 through T3. Through posterior approach with exposure of C6 to T3 level, the hematomatous mass was removed subtotally due to intraoperative bleeding and its ventral location. After the first operation, the weakness of bilateral lower extremities was improved so as to move gainst the gravity. But the next day, the limb weakness was aggravated as same as preoperative status due to mass effect of new hematoma. The second operation was performed to remove the hematoma and to control the bleeding focus. Several weeks later, the limb weakness was improved and he was able to walk. The literatures about spinal cavernous angioma are reviewed.

Cavernous hemangiomas were first reported in 1929 by Globus and Doshay, and are defined as benign vascular structures developed between the neural tissues occurring in the central nervous system, consisting of a dilated vascular bed. Cavernous hemangiomas comprise nearly 5-12% of all spinal vascular malformations; however, existence in the epidural space without bone involvement is rare. Only 4% of all cavernous hemangiomas (0.22/1.000.000) are purely epidural cavernous hemangiomas. In this case report, we removed a hemorrhagic thoracic mass presenting with progressive neurological deficits in a 55-year-old male patient. We found this case to be appropriate for presentation due to the rare occurrence of this type of cavernous hemangioma.

연구계획: 증례 보고 목적: 신경인성 종양과 유사한 흉요추부의 경막외 해면상 혈관종 환자를 보고하고자 한다. 선행 연구문헌의 요약: 뼈에 침습이 없는 경막외 해면상 혈관종은 매우 드문 질환으로 제한된 문헌 보고만이 존재한다. 대상 및 방법: 53세 여자 환자가 내원 한달여 전부터 시작된 좌측 하지의 감각저하를 동반한 저린 느낌을 주소로 내원하였다. 내원시 시행한 신경학적 검진에서 기타 다른 신경학적 이상 소견은 관찰되지 않았다. 자기공명영상에서는 흉추 11-12번간 좌측 추간공에 $2{\times}0.5cm$ 크기의 종괴가 관찰되었다. 수술을 시행하여 이를 완전 적출하였다. 결과: 병리 검사에서 해면상 혈관종이 확진되었다. 수술 부위의 약한 통증을 제외하고, 추적 관찰 2년동안 추가적인 신경학적인 증상 발생 없이 좋은 결과를 보였다. 수술 후 2년째에 촬영한 MRI에서 종양의 재발 소견은 관찰되지 않았다. 결론: 척추의 경막외 해면상 혈관종은 매우 드문 질환이며, 다른 경막외 병변들과 감별하기는 쉽지 않다. 그러나, 수술적 치료의 좋은 예후를 보이는 점을 감안하면, 경막외 병변의 감별진단시 이를 반드시 고려해야 할 것으로 생각한다.
