  • Brain injury causes persistent disability in survivors, and epidural hematoma(EDH) and subdural hematoma (SDH) resulting from cerebral hemorrhage can be considered one of the major clinical diseases. In this study, we attempted to automatically segment and hematomas due to cerebral hemorrhage in three dimensions based on computed tomography(CT) images. An improved GVF(gradient vector flow) algorithm was implemented for automatic segmentation of hematoma. After calculating and repeating the gradient vector from the image, automatic segmentation was performed and a 3D model was created using the segmentation coordinates. As a result of the experiment, accurate segmentation of the boundaries of the hematoma was successful. The results were found to be good even in border areas and thin hematoma areas, and the intensity, direction of spread, and area of the hematoma could be known in various directions through the 3D model. It is believed that the planar information and 3D model of the cerebral hemorrhage area developed in this study can be used as auxiliary diagnostic data for medical staff.

  • The treatment modalities of the intramural hematoma (IMH) remain controversial. Nowadays, the IMH of the descending thoracic aorta is generally classified in the medical treatment category. We describe a patient with IMH of the descending thoracic aorta who received the medical treatment. During the follow-up, we speculated that the IMH had been aggravated leading to an aortic rupture including hemothorax. Therefore, we performed an emergency operation. Contrary to our expectations, operative findings showed a well-organized aortic wall and serous pleural effusion. The exact diagnosis was IMH of the descending thoracic aorta with penetrating atherosclerotic ulcer (PAU). This case reminded us of the importance of accurate diagnosis and proper treatment.

  • 목적: 뇌내혈종이 발생한 경우 원인질환의 파악은 환자의 치료방법을 결정하는 데 아주 중요한 요소이다. 특히 악성 신생물에 의한 뇌내혈종의 발생을 파악하는 것은 초기 치료 방법의 결정 뿐 아니라 환자 예후의 결정에도 중요하다. 본 연구에서는 뇌내혈종 주위의 부종과 병변의 크기비를 이용한 원인질환 감별방법의 유용성에 대해 알아보고자 하였다.

  • Spinal hematomas are a rare but serious complication that is typically observed in the epidural space. Spinal subdural hematomas are a dangerous clinical situation because of their potential to cause significant compression of the neural elements and can be mistaken easily for spinal epidural hematomas. This paper reports a case of a severe whole lumbar subdural hematoma after a simple epidural injection that was treated with surgical decompression with excellent clinical results.

  • A pulmonary artery periadventitial hematoma is a rare complication of a Stanford type A intramural hematoma. As the proximal ascending aorta and pulmonary artery share a common adventitial layer, extravasated blood from the intramural hematoma in the ascending thoracic aorta may extend to beneath the adventitia of the pulmonary artery. The authors describe a case involving a 66-year-old male with acute chest pain who presented with a pulmonary artery periadventitial hematoma associated with a Stanford type A intramural hematoma.

  • Intramural hematoma of the aorta (IMH) is the precursor or a variant of a classic aortic dissection where hemorrhage occurs within the aorta wall in the absence of an initial intimal tear. IMH has a high rate of mortality and morbidity. The optimal therapy for IMH is uncertain, yet the involvement of the ascending aorta is usually considered as an indication for surgery due to the associated risk of rupture or cardiac tamponade. We report here on a case of a 71-year-old man who presented with syncope. Because of misdiagnosis, he underwent computed tomography (CT) after 5 hrs from arriving to the ER. Computed tomography of the aorta revealed intramural hematoma of the ascending aorta with cardiac tamponade. He also had vascular complications such as acute renal failure and visceral ischemia. We performed emergency graft replacement of the total arch and ascending aorta. He was discharged without complication on postoperative day 14.

  • Acalculous hemorrhagic cholecystitis is a rare complication of acute cholecystitis and is associated with a high mortality rate. We present a case of acalculous hemorrhagic cholecystitis with hematoma in the gallbladder lumen, which was diagnosed using magnetic resonance imaging (MRI). The T1- & T2-weighted MRI revealed gallbladder distension with a hypointense intraluminal hematoma. The excellent tissue contrast provided by MRI is useful for detecting hematomas in the cases of hemorrhagic cholecystitis.

  • Dissection intramural hematoma of the esophagus (DIHO) is a rare, but well-documented condition that is part of the spectrum of, acute esophageal injuries; these include the more common Mallory-Weiss tear and Boerhaave's syndrome. This disorder is predominantly seen in women during their sixth or seventh decade and the disease has various etiologies, but the pathogenesis has yet to be clarified. The triad of symptoms for this disorder includes retrosternal pain, hematemesis and odynophagia. It is important to differentiate esophageal submucosal dissection form other disorders that have a similar appearance, such as Mallory-Weiss syndrome and esophageal perforation because the prognosis of DIHO is excellent with conservative therapy and these other diseases require surgical treatment. We report here on a case of a dissecting intramural hematoma of the esophagus that was preoperatively misdiagnosed as the submucosal tumor of the esophagus preoperatively, and it was confirmed by Video-assisted thoracic surgery.

  • 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.
