  • Organized hematoma of the maxillary sinus is a rare, nonneoplastic benign lesion with locally destructive behavior that may mimic a malignancy. Clinically, symptoms do not usually occur while the lesion remains localized to the maxillary sinus. Because there is gradual enlargement of the lesion causing erosion and displacement of the adjacent bony structures, symptoms such as epistaxis, cheek swelling, nasal obstruc-tion, headache, and exophthalmos become manifest. Radiologically, unilateral cases are much more fre-quent than bilateral, and Waters' view shows complete opacity of the expanded maxillary sinus and some masses. CT scan shows a large heterogeneous enhancing mass causing considerable expansion of the max-illary sinus with bony erosion. On MR imaging, the mass usually has a variable signal intensity on T1- and T2- weighted images, ranging from low to high. After contrast administration, discrete areas of enhance-ment are present within the mass. Although the disease is essentially benign and nonneoplastic, differen-tial diagnosis from neoplastic disease including malignancy both clinically and radiologically has been always problematic. Accurate preoperative diagnosis of organized hematoma of the maxillary sinus is important to avoid unnecessary extensive surgery, because this condition is curative with a simple, conservative surgical approach and rarely recur. Organized hematoma of the maxillary sinus should be included in the differential diagnosis when patients have recurrent epistaxis, slow-growing mass of the cheek, nasal obstruction, and expansile mass in the maxillary sinus. A 33-year-old man was referred to the department of oral and maxillofacial surgery with a three-month history of slowly growing painful swelling of the left cheek. The mass of the maxillary sinus was resected by a Caldwell-Luc approach. Histopahtoly showed only a fibous encapsulated organized hematoma. To our knowledge, organized hematoma of the maxillary sinus has not been previously described in the Korean literature of the oral and maxillofacial surgery. We report a case of organized hematoma of the maxillary sinus presenting with an enlarging maxillary sinus mass.

  • Organized hematoma is a pseudo-tumorous lesion mostly occurs at sinonasal cavity and often confused with malignant neoplasm. The initiation of this lesion is blood accumulation, probably due to trauma, and this hematoma develops into organized hematoma as it encapsulated with fibrous band and neo-vascularized. Since it is uninformed at temporomandibular joint (TMJ) region, imaging diagnosis might be challenging. Also, delayed detection of mass involving TMJ is not uncommon due to confusion with joint disorder. Thus, this report introduced the rare pathology, organized hematoma on TMJ with advanced imaging features. Also, diagnostic point for early detection was described for the TMJ tumors and pseudo-tumors considering complexity of surgical intervention in this region.

  • 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, It necessary, should apply more diagnostic modalities than magnetic resonance images before deciding management plans.

  • Organized hematoma of maxillary sinus is a rare pathologically benign mass in which pressure in the hematoma increases as it undergoes a process of organization, causing the deformation of the surrounding tissue, mimicking malignancies. The midfacial degloving approach can be used when extensive exposure is required in the treatment of lesions or traumas in the midfacial area with intranasal and intraoral incisions. We report a surgical excision case of organized hematoma of maxillary sinus using midfacial degloving approach without major complications and recurrence after one-year follow up.

  • The authors present a case in which an organized chronic subdural hematoma(CSDH) was incidentally found in a 9-year-old boy with no significant medical history after a pedestrian traffic accident. Preoperative magnetic resonance(MR) imaging showed calcification on the inner membrane and an irregular heterogeneous structure in the hematoma cavity. The findings from the preoperative brain computed tomogram(CT) and MR image were very useful for making the preoperative diagnosis and surgical decision. In choosing the proper surgical strategy for removing the organized CSDH, it was thought that burr hole trephination would present unnecessary difficulties. Thus, craniotomy was selected and the organized CSDH was successfully removed with no complications.

  • The authors report a case of massive spontaneous intracerebral hematoma in a infant, caused by bleeding from cryptic vascular malformation associated with vitamin K dependant factor deficiency. The bleeding was initiated by vitamin K dependant factor deficiency, then 3 weeks later hematoma was expanded by rebleeding from malformed vessel after PT and PTT had been returned to normal values. The well circumscribed organized old hematoma with fresh expanded bleeding component within a huge rusty colored cystic fluid cavity was recognized in operative field and pathological ground.

  • Organized hematoma is a rare complication that can develop following gamma knife radiosurgery (GKS) for cerebral arteriovenous malformation (AVM). Here, we describe 5 patients with growing organized hematomas that developed from completely obliterated AVMs several years after GKS. The patients were 15, 16, 30, 36, and 38 years old at the time of GKS, respectively, and 3 patients were female. Four AVMs were located in the lobe of the brain, and the remaining AVM were in the thalamus. Between 2-12 years after GKS, patients developed progressive symptoms such intractable headache or hemiparesis and enhancing mass lesions were identified. Follow-up visits revealed the slow expansion of the hematomas and surrounding edema. Steroids were ineffective, and thus surgery was performed. Histology revealed organized hematomas with a capsule, but there was no evidence of residual AVMs or vascular malformation. After surgery, the neurological symptoms of all patients improved and the surrounding edema resolved. However, the hematoma continued to expand and intraventricular hemorrhage developed in 1 patient whose hematoma was only partially removed. GKS for cerebral AVM can be complicated by growing, organized hematomas that develop after complete obliteration. Growing hematomas should be surgically evacuated if they are symptomatic. Radical resection of the hematoma capsule is also strongly recommended.

  • Blunt abdominal trauma is commonly encountered in the emergency department. The lack of historical data and the presence of distracting injuries or altered mental status, from head injury or intoxication, can make these injuries difficult to diagnose and manage. We experienced a case of traumatic organized hematoma misdiagnosed as intra-peritoneal tumor with intestinal obstruction. A 52-year-old homeless male patient who have chronic alcoholism was admitted via emergency room with infra-umbilical abdominal pain. At admission, he was drunken status and so we could not be aware of blows to the abdomen. He had a unknown large operation scar on mid abdomen. A computed tomography (CT) scan showed the intestinal obstruction of the ileum level with 5.5cm sized mesenteric tumor. We performed adhesiolysis and widely segmental resection of small bowel including tumor with side-to-side anastomosis due to great discrepancy in size. He stated later that he was a victim of the violence before 3 weeks. A final pathologic report revealed well encapsulated, traumatic mesenteric hematoma with organizing thrombi, ischemia and abscess formation with multiple adhesion bands. Finally, the patient was discharged without complications on postoperative day 14.

  • 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.

  • Objectives : The aim of this study is to survey adverse events of acupuncture in the course of peripheral facial palsy treatments. Methods : The prospective observational study included patients hospitalized to receive acupuncture treatments for peripheral facial palsy. All patients were surveyed daily for adverse events associated with the acupuncture treatments applied the day before. Results : A total of 50 patients received $37.68{\pm}20.37$ acupuncture treatments in average. 36 patients reported experiencing at least one adverse event. Total 163 adverse events were reported. Common adverse events were bleeding(62), bruise(33), pain(30), tiredness(11), hematoma(7). The others were paresthesia(4), erythema(3), delay of removing needles(2), edema(2), aggravation of symptoms(2), declining of appetite(2), pruritus(1), drowsiness(1), anxiety(1), sweating(1), headache(1). Conclusions : Acupuncture has adverse events, like any therapeutic approaches. However, it is a relatively safe treatment. In future study, organized large scale prospective survey should be carried out to fully prove that acupuncture is safe.
