Spontaneous thoracic epidural hematoma occur rarely. We present a case of spontaneous thoracic epidural hematoma without any identified etiology and discuss the symptoms, signs and pathophysiology of this disorder. Early diagnosis and treatment by surgery can result in good recovery.

A prospectively study were conducted in 77 cases of delayed intracranial hematomas after head injury (male 59 cases, female 18 cases, aged from 17-60) in the Neurosurgery Department of Cho Ray Hospital from October 2001 to August 2002. The mainly reason of admission was traffic accident. Methods of surgery were wide decompressive craniotomy and removal of hematoma without bone flap. The results: good outcomes: 62 cases, moderate outcomes: 9 cases, death: 6 cases, reoperation: 3 cases. The development of intracerebral hematomas after head injury is very complex. It can occur immediately after injury or delay although initial CT scan is normal or shows slight contusion. Therefore, the doctors must examine closely head injuries to find out delayed intracerebral hematomas for prompt operation to lessen later sequellas and mortality

Review 39 patients with chronic post-traumatic subdural haematoma, who were treated at the 103 Hospital between January 2000 and July 2003. CT scan is a good method of diagnosis and select surgery. The methods of surgery concluded: Burr-hole cranniostomy for haematoma evacuation and irrigation and closed-system drainge are safe and effective method for treatment. Results: 92.3% patients with good outcome, recurrence occurred in 2 cases, airway injection in 2 cases, there wasn't death.

An organized hematoma in the maxillary sinus can be formed by organizing procedure of hematoma in the unaerated maxillary sinus. It is a rare disorder of unknown etiology. Clinical symptoms, signs, and radiologic appearance of the hematoma mimick tumors at the initial diagnosis. An expansile organized hematoma in the maxillary sinus may induce erosion or destruction of the maxillary bony wall. Therefore, it may be difficult to distinguish such lesion from malignant tumors. We report two cases of an organized hematoma in the maxillary sinus presenting with erosion of the maxillary sinus wall with a brief review of the literature.

OBJECTIVE: The goal of this study is to assess the prognostic factors of patients with chronic subdural hematoma. METHODS: A series of 150 patients with chronic subdural hematoma was reviewed. The hematoma was surgically removed in all patients. We analysed possible prognostic factors such as, age, sex, causes, preoperative radiologic findings, and preoperative neurological condition(Bender grade). RESULTS: The most important prognostic factor of chronic subdural hematoma was preoperative neurological condition. Patient's age and sex, causes and preoperative radiologic findings(hematoma thickness) do not have significant influences on the outcome. CONCLUSION: The neurological condition of the patients at the time of diagnosis and treatment are the only significant prognostic factor. Early diagnosis of chronic subdural hematoma before neurological deterioration is important.

Traumatic hematomas in the posterior fossa is relatively rare (only 2.8% in the total cases of hematomas in the cranium), but dangerous because clinical symptoms are not specific and sudden suspension of breathing may lead rapidly to mortality. The author had analysed these cases to find out experiences in the diagnosis and treatment of this disease. The rate of mortality after surgery and medical treatment was 14.3%.

An organizing hematoma with tumor-like presentation in association with a chronic subdural hematoma(CSDH) has not been reported. Most reported cases of an intracranial mass in association with a CSDH have been associated with primary or metastatic neoplasm. A 72-year-old man presenting with an intracranial contrast-enhancing mass in association with a CSDH in magnetic resonance images is reported. Operative exploration revealed the mass to be an organized hematoma adjoining cortical draining veins between the outer and inner membranes of a chronic subdural hematoma. This report adds another important differential diagnosis to various primary and metastatic neoplasms that have been reported in the literature when encountering an intracranial mass in association with a CSDH. Neurosurgeons should be aware of the possibility and, if necessary, should apply more diagnostic modalities than magnetic resonance images before deciding management plans.

A series of 89 patients diagnosed between 1988 and 1993 with computerized tomography(CT) as having subdural hematoma was studied retrospectively in order to evaluate the age of the subdural hematomas according to its appearance on CT scans. In all the patients, the interval from onset of injury to performance of CT scans was more than 2 days. The patients were divided into 4 groups based on the difference in density of the hematoma as seen on the CT scans;hyperdensity(16.9%), isodensity(30.3%), hypodensity(19.1%), and mixed-density(33.7%) groups. The mean interval from onset of injury to diagnosis in hyperdensity, hypodensity, mixed density, and isodensity groups was 15.7+/-18.3 days, 18.8+/-27.9 days, 35.6+/-62.1 days, and 47.6+/-52.1 days, respectively. The configuration of the hematomas on CT scans was crescentic in 74.2%, planoconvex in 12.4%, and biconvex in 13.5%. As the interval became longer, the hematomas tended to take on a planoconvex or biconvex shape rather than the crescentic shape;when the interval from onset of injury to diagnosis was within 7 days, crescentic shape was observed in 91%, within 8 to 21 days, 69%, and over 21 days, 58%. It is concluded from these findings that subdural hematomas undergo a progressive change in their attenuation as the hematomas age, changing from the initial hyperdense stage, go through a hypodense stage, and eventually to an isodense stage. These changes of attenuation values correlates fairly well with the rebleeding theory. The appearance of the hematomas as seen on CT scans also tended to change from the initial crescentic shape to the planoconvex or biconvex shape with time. However, given the possible variations of attenuation values and shapes of subdural hematomas, assumption of the age of the hematomas based on CT findings alone should be made with caution.

Diagnosis of arachnoid cyst has often been delayed and uncertain in the past, but development of computerized tomography has greatly improved the ease and accuracy of their identification, helping to provide for earlier surgical treatment and better care of patients. Arachnoid cysts of the middle cranial fossa may be associated with a unique complication, namely subdural hematoma. The hematoma with its membrane may be located either superficial to the cyst or within the cyst. Recently we have experienced two cases of arachnoid cyst of the middle cranial fossa with chronic subdural hematoma. We present the cases and their pathogenesis will be reviewed.

Spinal epidural and subdural hematomas are uncommonly recognized conditions. These conditions can result in severe irreversible neurologic deficits, if left untreated. Like intracranial lesions, these hematomas can expand rapidly and cause sudden spinal cord and/or cauda equina compression. This case is very rare in which is a concurrence of cervical spinal epidural and subdural hematoma after motor vehicle accident without spine fracture. The pathophysiology of these entities are discussed and the radiologic diagnosis focused on MR findings are reviewed. The importance of prompt surgical treatment is emphasized to facilitate good postoperative outcome.
