A 42-year old male patient was referred to the Department of Oral Medicine, Kyungpook National University Hospital due to the chief complaint of limite mouth opening. Three years ago, the patient was diagnosed as an infarction of both cerefellar hemispheres, acute obstructive hydrocephalus and acute epidural hematoma of frontal lobe at the department of neurosurgery.Both of the infarcted cerevellar hemispheres and the epidural hematoma of frontal lobe were removed with suboccipital and frontal craniectomu. After the brain surgery jaw opening range was decreased progressively and ultimately mouth opening became almost impossible. Spasmodic and rhythmic contractions of the masseter muscles occurred intermittently during daytime as well as sleeping. Food intake was available only through Levin -tube. Actibe jaw opening exercise was prescribed with the aids of tongue blades. A moist hot pack and indomethacin phonophesis were also applied 20 minutes three times a day to decrease discomfort muscle activities. After a month of treatments, the opening range was increased to 5mm at the premolar area and oral food intake was possibel. The L-tube was removed and the patient was discharged.

Angiosarcoma of the brain, either primary or metastatic is extremely rare. Moreover, angiosarcoma metastazing to the brain is also highly unlike to occur when comparing with metastases to the other organs. Thus, an ideal treatment strategy has not been established. A 67-year-old man with past surgical history of a scalp angiosarcoma underwent surgical resection of intracranial invasion. Because of wide scalp flap excision and resultant poor vascularity of the scalp flap, additional radiation was not provided. Because adjuvant therapy is impossible due to poor scalp condition, more careful but ample resection of the primary lesion is essential to conduct initial operation.

Diagnosis of cerebral syphilitic gumma is frequently determined at the time of surgery, because imaging and laboratory findings demonstrate the elusive results. A 59-year-old woman presenting dysarthria showed a mass on her brain computed tomography. She was first suspected of brain tumor, but histological results from surgical resection revealed cerebral gumma due to neurosyphilis. After operation, she presented fever and rash with an infiltration on a chest X-ray. Histological assessment of skin was consistent with syphilis. Fluorescent treponemal antibody absorbed test IgG in cerebrospinal fluid was positive. She was successfully treated with ceftriaxone for 14 days.

Hypothalamic hamartoma (HH) is a benign indolent lesion despite the presentation of refractory epilepsy. Behavioral disturbances and endocrine problems are additional critical symptoms that arise along with HHs. Due to its nature of generating epileptiform discharge and spreading to cortical region, various management strategies have been proposed and combined. Surgical approaches with open craniotomy or endoscopy, stereotactic approaches with radiosurgery and gamma knife surgery or radiofrequency thermos-coagulation, and laser ablation have been introduced. Topographical dimension and the surgeon's preference are key factors for treatment modalities. Endoscopic disconnection has been one of the most favorable options performed in treating HHs. Here we discuss presurgical evaluation, patient selection, surgical procedures, and complications.

Recently, evaluation of brain transport of taurine which is possible to effect on Alzheimer's disease has investigated in rats. Also, internal carotid artery perfusion (ICAP) method is very useful for measuring of blood-brain barrier (BBB) permeability in rats. But ICAP has difficulties to evaluate of BBB permeability in mice especially. In the present study examines neuropharmaceutials permeability through the BBB in mice by common carotid artery perfusion (CCAP) method that modify ICAP method and require simple surgery. The external carotid artery (ECA) is cannulated with coagulating pterygopalatine artery (PPA) on ICAP method, while CCA is cannulated without coagulating PPA on CCAP method. The CCAP method require 4-5 fold higher infusion rate than ICAP method because an additional factor of 2 must be incorporated to adjust for fluid loss to the extracerebral circulation.

A mucocele is an epithelium-lined, mucus-filled cavity in the paranasal sinuses. Mucocele may develop due to scarring and obstruction of the sinus ostium caused by midface sinus trauma, such as orbital bone fracture or endoscopic sinus surgery. The authors report two cases of orbital mucocele as complications following midface sinus injury (endoscopic sinus surgery in one case, and orbital fracture repair in the other). In both cases, imaging studies showed a large orbital mucocele accompanied by bony erosion and orbital wall remodeling, compressing the ocular muscle. Using an open approach, the lesion was excised and marsupialized. The symptoms resolved, and the postoperative eyeball position was normal. Orbital mucocele may cause serious complications such as ocular symptoms, orbital cellulitis, osteomyelitis, and the formation of an abscess with the potential to invade the brain. Therefore, surgeons should consider the possibility of mucocele as a late complication of surgery and initiate an immediate work-up and surgical treatment if needed.

Primary pulmonary meningioma is a rare disease, and chordoid meningioma is an uncommon variant of meningioma in the central nervous system (CNS) with a high recurrence rate. We report a case of primary pulmonary chordoid meningioma that presented as a solitary pulmonary nodule (SPN). The SPN was resected by thoracoscopic wedge resection and was revealed to have characteristics of chordoid meningioma. After confirming the absence of a meningioma in the CNS by brain imaging, the nodule was diagnosed as a primary pulmonary chordoid meningioma. The patient remained disease-free after 26 months postoperatively. To our knowledge, this is the third case of primary pulmonary chordoid meningioma to be reported.

A 67-year-old man visited our plastic surgery clinic complaining of a palpable protruding mass (2.0×2.5 cm) in the right occipital region. To establish an appropriate treatment plan for the cystic mass, brain magnetic resonance imaging was performed. A 2.2 cm nodular lesion with peripheral enhancement in the right occipital region of the scalp was confirmed. In addition, two rim-enhancing nodular lesions up to 9 mm with marked perilesional edema in the right frontal lobe were confirmed. The findings suggested metastasis from cancer. After further evaluations, a mass in the right lower lung field was identified as adenocarcinoma of the lung. Histological examination characterized the excised lesion as a cutaneous metastasis from lung adenocarcinoma. This case report shows that a cystic mass, which commonly occurs in the scalp, may indicate lung cancer. In particular, if a cystic mass of the scalp is identified in a person at high risk for lung cancer, appropriate evaluation and urgent treatment should be performed.

Pneumocephalus after thoracoscopic excision of a mediastinal mass is a very rare complication. It presumably occurs due to dural injury near the spinal root and development of a subsequent subarachnoid-pleural fistula. A 60-year-old woman complained of nausea and headache after thoracoscopic excision of a posterior mediastinal mass. She was diagnosed with pneumocephalus by brain CT and recovered with supportive management.
