A 65-year-old woman had been conservatively treated as idiopathic trigeminal neuralgia for over 25 years, because conventional computed tomography (CT) and magnetic resonance imaging(MRI) showed no abnormality in the cerebello-pontine(CP) angle cistern. She received a detailed MRI by constructive interference in steady state and diffusion weighted image(DWI) sequences. Those sequences on MRI well demonstrated a epidermoid tumor in the CP angle cistern, and the removal of the tumor completely resolved the neuralgia. Since a small epidermoid in the CP angle cistern seems to be unrecognized by conventional CT and MRI, detailed evaluation by DWI sequence, which has been widespread recently, is required for patients with trigeminal neuralgia.

When a patient presents with persistently unilateral head or face pain, cluster headache and trigeminal neuralgia should be considered. Diagnosis is based on the patient's history; anatomical studies are performed only to rule out problems other than tumor or stroke. A patient who presents with pain in the pharynx, tonsils, and ear--particularly if it is initiated by swallowing, yawning, or eating--may have glossopharyngeal neuralgia. Treatment with carbamazepine is indicated; if the patient does not respond to this drug, the diagnosis is doubtful. Several effective treatments are available for these conditions. Oxygen, drug therapy, or surgery may be indicated depending on the course of the disease.

This case report first reviews the intracranial tumors associated with symptoms of trigeminal neuralgia (TN). Among patients with TN-like symptoms, 6 to 16% are variously reported to have intracranial tumors. The most common cerebellopontine angle (CPA) tumor to cause TN-like symptoms is a benign tumor called an acoustic neuroma. The reported clinical symptoms of the acoustic neuroma are hearing deficits (60 to 97%), tinnitus (50 to 66%), vestibular disturbances (46 to 59%), numbness or tingling in the face (33%), headache (19 to 29%), dizziness (23%), facial paresis (17%), and trigeminal nerve disturbances (hypesthesia, paresthesia, and neuralgia) (12 to 45%). Magnetic resonance imaging with gadolinium enhancement or computed tomography with contrast media are each reported to have excellent abilities to detect intracranial tumors (92 to 93%). This article then reports a rare case of a young female patient who was mistakenly diagnosed and treated for a temporomandibular disorder but was subsequently found to have an acoustic neuroma located in the CPA.

Recent advances in optics, video systems and endoscopic operating instruments have led to increasing application of thoracoscopic surgery, as it has become easier to perform and more accurate. We performed 586 video-assisted thoracic surgical procedures for diagnosis and treatment (May 1992-Dec. 1998) 127 were for diagnostic thoracoscopy and 79 for pleurodesis. 380 cases of operative thoracoscopy included pulmonary wedge resection (for interstitial lung disease, benign and malignant pulmonary tumors and pulmonary metastases) bullectomy, management of empyema, pleural tumor biopsy, thoracic sympathectomy, pericardial window formation, thoracic spinal procedures and resection of posterior mediastinal cysts. Recently we have had good experience in evacuating blood and blood clots from the thorax which accumulated after cardiac and thoracic surgery. Patients were placed in the lateral thoracotomy position and were ventilated with a double-lumen endotracheal tube, enabling collapse of the operated lung. The operating approach was through 1-3 thoracic ports. Mean operation time was 55 minutes, chest-tubes remained for 2.2 days (mean) and mean hospitalization was 3.3 days. There were no wound infections or significant postoperative complications. 5 patients had air leaks longer than 7 days; none required further surgical intervention. There was intercostal neuralgia and Horner's syndrome after thoracic sympathectomy (1 each) In cases in-which localizing the parenchymal lesion was difficult, the lung was palpated directly by inserting a finger through a small incision or a mini-thoracotomy. Conversion to thoracotomy was performed when primary malignancy of lung was diagnosed by frozen section. Only 2 patients had thoracotomy for uncontrolled bleeding. Thoracoscopy is a minimally invasive surgical technique with very low morbidity and high diagnostic accuracy. Postoperative recovery is brief and uneventful.

The clinic association between tumors in the neck and syncopal attacks has been well documented but uncommon. The pathogenesis of this type of syncope has been attributed to an specific sinus node disfunction and several diseases that affect pacemaker activity, cardiac output and blood supply to the brain are able to produce it. The most common reflex cardiovascular sindromes linked to the IX nerve are carotid sinus syndrome and glossopharyngeal neuralgia-asystole syndrome. Some patients with a pathological involvement of the parapharyngeal space also suffers from syncope but the clinical picture of these patients differs so greatly from the other two syndromes, which suggests specific aetiological, clinical and therapeutical features so the term "parapharyngeal space lesiones syncope-syndrome" has been proposed for this entity. We report a case of a patient with a neck tumor in the parapharyngeal space with syncope as the major symptom.

This report describes a case of metastatic meningioma involving the first thoracic vertebral body in a 63-year-old woman. The patient was treated surgically 10 years earlier for a benign meningioma of the right parietal vault. Local recurrence was diagnosed in 1992. Despite the gamma-knife radiosurgery, recurrence required surgical treatment in 1999. Histological findings were compatible with atypical meningioma (grade II WHO). One year later, the patient presented left C8 cervicobrachial neuralgia. Investigation led to discovery of a D1 tumor that was a metastasis of the atypical intracranial meningioma. A resection of the vertebral T1 body with C7-T2 osteosynthesis was performed with an excellent recovery and no postoperative complication.

A retroperitoneal cystic mass compressing the right psoas muscle was found incidentally by ultrasonography in a 67-year-old woman. The radiological findings and a history of costal caries led us to suspect a psoas cold abscess. Ultrasound-guided needle aspiration was done to establish the diagnosis and to drain the content, but only a small amount of sterile fluid was obtained. The patient complained of neuralgia in her right leg at the time of puncture. Under the preoperative diagnosis of a neurogenic tumor, the mass was surgically resected, and found to be filled with old blood. The solid region consisted of a proliferation of fusiform cells, leading to a diagnosis of benign schwannoma. Retroperitoneal schwannoma is often misdiagnosed as an adjacent anatomical structure. Thus, we conclude that both microbiological and cytological examination of an aspiration specimen is important when psoas abscess is considered in a differential diagnosis.

Primary central nervous system lymphoma of non-Hodgkin's type are distinguished from systemic non-Hodgkin's lymphoma because of their different pathobiological behaviour. Predisposing factors are pharmacologically induced immunosuppression and those referring to diseases. We present the case of a patient who was sent to hospital in case of emergency due to pain of one half of the face. The symptoms corresponded essentially to neuralgia of the trigeminal nerve. During course other neurological symptoms showed up. The right diagnoses of a primary central nervous system lymphoma of non-hodgkin's type was finally made post mortem. The case especially reveals the difficulties of diagnosis - including negative and confusing MRI-findings - and the variety of differential diagnosis of this also in not immunosuppressed persons more and more frequent kind of tumor.

The article presents a case of 42-year-old patient with Recklinghausen disease treated in the outpatient clinic for 5 years for hyperaesthesia of a thumb. On physical examination the thumb was painful but smooth, soft with no features of infection. Neuralgia and Raynaud syndrome were suspected. Additional investigations did not show significant abnormalities, however, successive forms of conservative treatment (including denervation of the thumb) were not successful. Instant, persistent pain caused by even a slight touch or thermal changes suggested glomus tumor of the thumb. Physical examination did not confirm a lump typical in this disease. Finally partial resection of the digital pulp was performed, which led to complete recovery. Histopathological examination confirmed glomus tumor of the thumb.
