INTRODUCTION: Intracranial colloid cysts are rare benign tumors located in the region around the foramen of Monro or around the third ventricle with an annual incidence of 3 of 1,000,000. The common clinical picture is a progressive headache due to the rapid enlargement of the cyst, resulting in hydrocephalus as it obstructs the cerebrospinal flow; brain herniation may ensue, leading to death. OBJECTIVES: The objectives of this report are to (1) present a case of intracranial colloid cyst in a young female with neurofibromatosis type 1, (2) emphasize the importance of early diagnosis by clinical signs and symptoms and (3) highlight the importance of neuroimaging in arriving at a neurologic diagnosis. CASE REPORT: A nineteen-year-old female was seen due to a three-month history of progressive headache, with associated signs of increased intracranial pressure and with a medical history of neurofibromatosis type 1, inherited from her mother. Neurologic findings revealed papilledema and 6th cranial nerve palsy. By radiographic imaging with clinical correlation, patient was diagnosed with a colloid cyst obstructing the foramen of Monro. Surgical intervention was done and patient improved without complications. DISCUSSION Neurofibromatosis is a hereditary neurocutaneous syndrome in which the skin, nervous system, bones, endocrine glands and sometimes other organs are the sites of a variety of congenital abnormalities, often taking the form of benign tumors. Intracranial colloid cyst was seen in this case report. Colloid cysts have an incidence of 0.5 – 1% of all primary brain tumors and are the most common masses in the third ventricle and in the Foramen of Monro. They cause obstruction of CSF flow, resulting in hydrocephalus. No published case of neurofibromatosis type 1 patients with a symptomatic intracranial colloid cyst has been reported yet. Surgical resection is the treatment of choice for colloid cyst.

Neurogenic tumors are common in posterior mediastinal tumors and neurilemmoma represents approximately 40% of neurogenic tumors arising in the mediastinum. It is usually asymptomatic, and is generally diagnosed incidentally. In some cases, they presented with symptoms of nerve or airway compression. However, a solitary neurilemmoma, particularly not associated with von Recklinghausen disease, with spontaneous hemothorax is quite rare. We report a case of spontaneous massive hemothorax associated with a solitary neurilemmoma.

The incidence of multiple meningiomas found prior to the introduction of CT was 1~2%, the incidence since the introduction of CT was 8.9%. The authors report a case of multiple meningiomas without evidence of von Recklinghausen's disease. The possible presence of more than 1 tumor in a patient with an intracranial meningiomas must always be kept in mind. The pathogenetic factors related to true multiple meningiomas in unknown. We report a patient with multiple meningiomas which was confirmed by operation.
