Objective : The authors present three cases of brain tumors in which epidural hematomas(EDHs) were developed postoperatively in the remote areas from craniotomy sites. The preventive tactics as well as possible mechanisms of development of remote EDH are discussed. Material and Methods : The magnetic resonance imagings of three patients revealed a left lateral ventricular mass located just aside of foramen Monro in a 27-year-old male, a large cystic mass in the temporal lobe in a 35-year-old male, and a partially calcified pineal mass in a 27-year-old male patient. The surgical removals of these tumors were performed without any noticeable events during surgery via left frontal transcortical transventricular approach for lateral ventricular tumor, left temporal craniotomy for cystic temporal tumor, and right occipital transtentorial approach for pineal tumor. Results : Postoperative EDHs remote from the sites of craniotomy were detected by the immediate postoperative computerized tomographic scans. We obtained good outcomes without any morbidity in all three patients with emergent evacuation of the hematoma. The pathologic diagnoses were lateral ventricular ependymoastrocytoma, temporal craniopharyngioma and mixed germinoma of the pineal region. Conclusion : It is postulated that a sudden reduction of intracranial pressure(ICP) at the time of tumor removal may strip the dura from the inner table of the skull to cause EDH from the remote site of craniotomy. Gradual reduction of ICP with slow drainage of cerebrospinal fluid before tumor removal as well as lowering the head position of patient during surgery might be helpful for preventing this unusual complication.

Nonsurgical management of four cases of the parasagittal epidural hematoma were experienced. Patients were mildly symptomatic or minimal neurological disturbances on admission. Patients were treated conservatively because of stable neurologic sign. All patients had who diastatic fracture and/or suture have become a complete neurological recovery with satisfactory absorption of EDH over a period of 5 to 12 weeks.

Spinal epidural hematoma (SEH) can occur naturally or traumatically and is most common in patients with an underlying disease of the vascular structure or coagulation disorder. Most SEHs occur naturally for no apparent reason, and epidural hematoma caused by trauma is less common, comprising 1.0%-1.7% of total spinal injuries. Few reports of SEH induced cauda equine syndrome resulting from low-energy injury caused by osteoporotic vertebral compression fractures are available. The authors experienced a case of delayed SEH after hemorrhage due to a low-energy injury in an elderly patient. No cases in Korea have been reported; therefore, this case is reported with a review of the relevant literature.

The purpose of this study was to investigate the importance of continuous and detailed follow-up of patients after spinal surgery by reviewing the literature on epidural hematoma and the lower court ruling on lumbar MRI during the judgment on the negligence of postoperative follow-up. In the case of neglecting MRI examination or cooperation after surgery, delaying MRI examination after pain and symptom appeal after surgery, and returning home immediately after neurological symptom development after surgery, negligence in progress observation was recognized. In the case of the case where the negligence was not recognized even after the occurrence of the aftereffects by taking measures against the symptoms, and the case where the scope of the doctor's discretion for the execution of the test was recognized, It is hoped that this study will help prevent medical accidents and disputes related to follow-up after spinal surgery by increasing awareness of the importance of prompt MRI examination, diagnosis, surgical treatment, and power, especially in the case of new neurological symptoms.

One of the most serious complications of regional anesthesia is a neurological deficit. Although such a problem is very rare, obstetric patients may develop paresthesia and motor dysfuntion during the postoperative period in association with number of other factors, including direct nerve trauma, equipment problems, adhesive arachnoiditis, anterior spinal artery syndrome, epidural hematoma or abscess and adverse drug effect. We experienced a case of unilateral paraparesis following epidural anesthesia with 20 ml of 0.75% ropivacaine and $25{\mu}g$ of fentanyl in an obstetric patient.

The trigger point injection technique is widely used in pain clinics for the treatment of acute and chronic pain. Yet it has a variety of complications such asvasovagal syncope, total spinal anesthesia, paralysis, root block, pneumothorax, needle breakage, skin infection, and hematoma formation. Among them, the simultaneous occurrence of psoas and epidural abscesses is extremely rare. We report here on a patient who was diagnosed with epidural and psoas abscesses after paravertebral trigger point injection.

Epidural adhesiolysis is a convenient and safe method for the management of back pain. However, we experienced a case where a patient developed sensory change to S2 area after epidural adhesiolysis. Male patient, 43 years old, was admitted to our pain clinic for epidural adhesiolysis for back pain. Patient was experiencing pain radiating to left thigh, and sensory change and motor disturbance to the S1 area. Patient's symptoms and signs were much improved on the first day of epidural adhesiolysis. Patient, however, complained of numbness of perineal and S2 areas after the next day of injections. We postulated the cause of this complication was due to: compression of nerve root by the large volume of injectate and hematoma, and the side effect of local anesthetic, hypertonic saline and steroid.

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.

Ventriculoperitoneal [VP] shunt is a common treatment for hydrocephalic patients. However, complications, such as shunt tube occlusion, infection, intracranial hemorrhage, seizure can occur. Of these, intracranial hemorrhage may occur due to intracranial vascular injury or a rapid decrease of intracranial pressure [ICP]. Most of these hemorrhages are subdural hematomas [SDH] while a few are epidural hematomas [EDH]. It is extremely rare for an intracranial hemorrhage to occur due to an extension of the bleeding from an injured extracranial vessel. We report two cases of EDH due to occipital artery injury following VP shunt and extraventricular drainage [EVD].

Objective: Symptomatic chronic subdural hematoma(CSDH) is a well-known neurosurgical entity and most of the lesion is managed by surgical treatment. The authors analyze the surgical indication and the treatment results of twist drill craniostomy with closed-system drainage(TDD) for the symptomatic CSDH. Methods: From March 2001 through December 2003, 31 patients who were treated with TDD for the symptomatic CSDH and followed more than 6months were included. The radiologic criteria of TDD in this study were 1) homogeneous density of hematoma on computed tomography(CT), 2) no septation of hematoma on magnetic resonance imaging(MRI), and 3) thicker hematoma more than twice thickness of skull. Surgical procedures were performed on the maximum thickness of hematoma on CT/MRI. Short and long Steinman pins were used to penetrate the skull and hematoma membrane. As the 5L catheter was inserted through the drill hole, it was kept for 1 - 7days for the drainage of CSDH. The patients of CSDH were followed with clinical symptoms and CT studies. Results: Most of all the 31 patients were improved. However, one patient was suffered from postoperative epidural hematoma and the other patients have received the secondary operation because of the recurrence of CSDH on 3 months after initial surgery. Conclusion: TDD is safe procedure for the symptomatic CSDH if the patients are selected appropriately.
