Cystic Intracranial Hemangiopericytoma; Case report

Hemangiopericytomas is a rare malignant tumor of the central nervous system having an incidence of 1-3.8% of all primary intracranial meningeal tumors, and the occurrence of cystic hemangiopericytomas is even rarer. We report our recent experience of a case of cerebral hemangiopericytoma associated with a large cyst in a 38 year-old man. The patient presented with 1-month history of headache. Computerized tomography(CT) and magnetic resonance image(MRI) showed a huge-sized, cystic tumor in the left frontal region. Histopathological report of the excised tumor confirmed cystic hemangiopericytoma. Over the years, the issue of classifying hemangiopericytoma as a form of meningioma has been controversial. Since hemangiopericytoma differs from that of ordinary meningiomas because of its extremely malignant behavior and different histological and ultrastructural properties, the author suggest that hemangiopericytoma classified not with meningiomas. Regardless of classification, total surgical removal of this tumor is crucial due to its tendency for local recurrence despite aggressive resection.

A case of laryngeal cleft

Laryngotracheoesophageal cleft is a rare congenital anomaly characterized by a midline defect of variable length between the posterior larynx and trachea and the anterior wall of the esophagus which was first reported by Richter in 1792. The male, birth weight 2780 gm, was born our hospital, After birth the infant breathed spontaneously, cried immediately but weak and did well initially but after minutes appeared moderate amount of mucus in the mouth, and sterile water was given but immediately vomited with chocking, cough and cyanosis. A nasogastric tube was inserted through the esophagus without resistance and kinking. Esophagogram was showed spillage of contrast media simultaneously into trachea and esophagus. In direct laryngoscopy, there appeared to be small laryngeal cleft posteriorly, to the level of vocal cord. But bronchoscopy could not be performed due to narrow tracheal orifice. So we confirmed the laryngeal cleft by means of CT and MRI of neck. CT and MRI scan of neck demonstrated a cleft in interarytenoid lesion and connection between esophagus and laryngeal lumen.
