심장과 대혈관 기원의 원발성 종괴는 매우 드물다. 그중에서도 악성 말초신경초종은 더 드물게 보고되었다. 76세 남성에서 발견된 흉수의 원인 평가를 위해 시행한 조영증강 컴퓨터단층촬영에서 우폐정맥과 좌심방을 침범하는 저음영의 종괴가 발견되었고 초음파상 우폐정맥에서 기인한 종괴로 의심되었다. 종괴는 수술적 절제를 통해 폐정맥 기원의 악성 말초신경초종으로 최종 진단되었다. 저자들은 국내에서 보고된 바가 없는 드문 증례인 폐정맥 기원의 원발성 악성 말초신경초종을 보고하고, 종괴가 폐정맥 기원임을 시사하는 영상의학적 소견에 대해 고찰하고자 한다.

Intraneural hematoma is a rare disease that results in an impaired nerve function because of bleeding around the peripheral nerve, with only 20 cases reported. Trauma, neoplasm, and bleeding disorders are known factors for intraneural hematoma. However, here we report atypical features of asymptomatic and spontaneous intraneural hematoma which are difficult to diagnose. A 60-year-old woman visited our clinic with the complaint of a palpable mass on the right calf. She reported no medical history or trauma to the right calf and laboratory findings showed normal coagulopathy. Ultrasonography was performed, which indicated hematoma near saphenous vein and sural nerve or neurogenic tumor. We performed surgical exploration and intraneural hematoma was confirmed on sural nerve. Meticulous paraneuriotomy and evacuation was performed without nerve injury. Histological examination revealed intraneural hematoma with a vascular wall. No neurologic symptoms were observed. In literature review, we acknowledge that understanding anatomy of nerve, using ultrasonography as a diagnostic tool and surgical decompression is key for intraneural hematoma. Our case report may help establish the implications of diagnosis and treatment. Also, we suggested surgical treatment is necessary even in cases that do not present symptoms because neurological symptoms and associated symptoms may occur later.

Schwannomas are tumors which originate from the neuroectodermal Schwann cell of cranial, intraspinal, peripheral and autonomic nerve sheaths, and they are solitary, benign, slow growing and well encapsulated neoplasm. Schwannomas are usually asymptomatic. No strong gender or age predominance exists. The incidence of extracranial schwannomas in the head and the neck region varies from 25~45%. In addition, schwannomas are rare in the maxillary sinus or buccal space. In this paper, it diagnosed and treated a 54-years old female patient, who had schwannoma in the maxillary sinus derived from infraorbital nerves, the branch of the left trigeminal nerve, and a 19-years old male patient, who had schwannoma arose in the buccal space derived from the buccal branch of the right facial nerve. There was no particular complication except sensory extinction of the nerve in the female patient and paralysis by the nerve in the male patient. It is determined those two cases of schwannoma in the rare portion is valuable and herein, it reports those with literature discussions.

Riedel's thyroiditis is an uncommon disorder of unknown etiology that is characterized by an invasive process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation as a stonyhard, poorly defined enlargement over the thyroid gland and local compression of the trachea, esophagus and recurrent laryngeal nerve can mimic invasive thyroid carcinoma and mask the accompanied thyroid neoplasm. A case of Riedel's thyroiditis in a 59-year-old female patient, admitted with a previous diagnosis of adenomatous goiter, is reported. So, we present this case with the review of literatures.

이 보고서에서는 최근에 저자 등이 5-100단백질을 함유하고 있는 아주 드문 폐 실질안의 신경종양을 경험하 였기에 보고하고자 한다. 이 환자는 47세 남자로 평소 증상은 없었으나, 신체검사에서 우연히 발견된 좌측 폐문의 종피를 주소로 내원한 자이다 이 종괴의 정확한 진단 및 치료를 위하여 수술을 시행하였으며, 병리 조직학적 검사에서 원발성 폐실질내 신경초종으로 판명되었다. 특수염색검사에서 종양안의 5-100단백질의 존재를 확인할 수 있었다.

Background: Neuroblastoma is the third most common malignancy of chidhood, and is the most common mediastinal mass in children under the age of 2 years. However, the results of surgical treatment have been seldomly reported in Korea. Therefore, we analyzed the results of surgical treatment in children with neuroblastoma and its influencing factors. Material and Method: We studied the clinical characteristics and prognosis of 12 children, 11 makes and 1 female, whose primary thoracic neurobalstomas or ganglioneuroblastomas were diagnosed and operated between 1977 and 1997. Men age at presentation was 29.9 months. Result: Respiratory symptoms were the modes of performed in 9 patients. Complete excision, partial excision, and biopsy only were performed in 9, 2, and 1 patients respectively. Ten patients of thoractic neuroblastomas survived (83.3%) during follow-up period. Conclusion: The postoperatve 5-year survival of thoracic neuroblastoma was 76.4% and the prognosis was related to the stage of neuroblastoma. We suggest that complete resection should be considered as preferential method in the treatment of thoracic neuroblastoma in children, especially with early stage.

Sclerosing polycystic adenosis (SPA) is a rare, asymptomatic disease that occurs mainly in the salivary glands. We report the case of a 51-year-old man who presented with trismus and pain upon mouth opening. Magnetic resonance imaging revealed a 2-cm mass located in the anterior portion of the left parotid gland. SPA was diagnosed based on histopathological examination of the surgical specimen. In pathologic findings, there was a well-circumscribed multicystic nodule in the parenchyma. Dense fibrosis and chronic non-specific inflammatory cells were observed in the stroma. In 13 previous reports on SPA, the most preferred treatment was superficial or total parotidectomy. This report suggests that simple excision of SPA preserves facial nerve function and facial volume.

A traumatic or amputation neuroma can develop as a result of nerve injury caused by hemorrhage, infection, ischemia, trauma, etc. A traumatic neuroma can be considered as the attempted regeneration of the amputated nerve rather than a true neoplasm. Occasionally, a traumatic neuroma will develop after oral or maxillofacial surgery. Here, we report a case of traumatic neuroma after mandibular angle reduction in a 24-year-old woman.

Subarachnoid-pleural fistula after routine thoracotomy is a rare complication but a very serious problem. Twenty one cases have been reported in the literature. We report a care of subarchnoid-pleural fistula that dveloped after the esecation of posterior mediastinal neurogenic tumor. The patient presented with large amount of clear pleural fluid with mild headache and dizziness. Surgical intervention following a trial of conservative therapy was undertaken because we strongly suspected subarachnoid-pleural fistula. A dural tear was found at the level of resected intercostal nerve root. The dura was closed by way of direct suture and fibrin glue. In this case, the recognition of subarachnoid-pleural fistula formation is difficult because the patient had not presented any neurologic deficit.

Nasopharyngeal cancer is malignant tumor of nasopharyngeal area that is characterized of lymphadenopathy, pain, otitis media, hearing loss and cranial nerve palsy and may present symptoms similar to temporomandibular disorder such as facial pain and trismus. In this case, the patient with symptoms similar to temporomandibular disorder after surgery for otitis media presented with facial paresthesia and masticatory muscle weakness. Examinaion of trigemimal nerve was shown sensory and motor abnormaility. The patient was referred to a neurologist. Nasopharyngeal cancer was suspected on computed tomography and magnetic resonance imaging and was confirmed by biopsy. If the patient presenting with paresthesia and muscle weakness the cranial nerve examination should be performed regardless of typical temporomandibular disorder symptom. The neurologic symptom can be caused by neoplasm such as brain tumor and nasopharyngeal cancer. Nasopharyngeal cancer on rosenmuller fossa can develop otitis media. Therefore, the patient with otitis media history should be consulted to otorhinolaryngologist to examin the nasopharyngeal area.
