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.

Central neurocytoma is a rare benign tumor of the central nervous system occuring in young adults and typically located in the ventricles. The tumor is composed of small round cells with neuronal differentiation and has a favourable prognosis. We report two cases of giant central neurocytomas with a triventricular extension in two young women. The first case concerned a 26 years old righthanded woman in whom an intraventricular mass was discovered, after a car accident with head trauma. Skull radiography showed an enlargment of the sella turcica. A CT scan performed in order to examine the pituitary gland revealed a voluminous and heterogenous intraventricular tumor with calcification. The second case concerned a 26 years old righthanded woman, presenting with a 4 Glasgow Coma Scale Score preceded by an acute onset of headache with projectile vomiting. A CT scan performed in emergency revealed a voluminous intraventricular mass with significant hydrocephalus. We review the different pathological and topographical patterns of previously published neurocytomas and discuss surgical management, effectiveness of radiation therapy and biological behavior.

Osteoma is a benign, slow-growing tumor, which mainly occurs in the bones and cavities of the middle third of the face, representing the most frequent benign tumor of the paranasal sinuses. Osteoma of the paranasal sinuses is generally asymptomatic and it is discovered only as a coincidental radiological finding; when it becomes symptomatic, the most common presenting symptoms are headaches and facial pain. Rarely the sinusal osteoma may entail secondary orbital extension, with ocular signs and symptoms. Primary intraorbital involvement is extremely rare. The authors present a review of the literature and report two cases of primary orbital osteoma. In both cases surgical treatment led to the complete remission of symptoms. Diagnosis and surgical therapy are discussed.

We report an unusual case of giant extradural epidermoid cyst of the posterior fossa in a 73-year-old man. The patient presented headache and gait disturbance for 3-4 months, cerebellar ataxia, left cerebellar dysmetria, and perturbed balance. The CT-scan showed a huge posterior fossa extradural lesion with a small area of peripheral contrast enhancement. Outcome was good after total resection of the lesion via a suboccipital approach. Pathology reported an epidermoid cyst. Extradural epidermoid cyst is a rare benign tumor of the skull which sometimes can reach considerable size. It is a slow growing lesion and may cause mild neurological deficits. The goal of surgical treatment is total resection of the tumor with its capsule. The long-term prognosis is excellent after successful resection.

Lipoma of the retropharyngeal space is a very rare benign tumor often causing unspecific clinical symptoms. The most common symptoms are dysphagia and/or respiratory disturbances. The clinical diagnosis may be difficult. The radiological imaging techniques (CT and MRI) can provide adequate information with regard to the composition and extension of the tumor, although final histological confirmation is essential. Surgery is the treatment of choice. We present a case of 40-year-old male patient complaining of obstructive sleep apnea symptoms (respiratory disturbances, excessive daytime somnolence, morning headache). The radiological examination (CT) showed a huge (11.7 x 7.2 cm) lipoma of the retropharyngeal space extending from the nasopharynx to the superior mediastinum. The tumor was removed via transcervical approach with complete amelioration of symptoms.

Facial nerve hemangioma is a rare benign tumor that originates from the venous plexus surrounding the facial nerve. A case of facial nerve hemangioma in the geniculate ganglion was reported. A 47-year-old man was referred with a left progressive facial palsy over 1 year. There were no complaints of associated hearing loss, tinnitus, headache, dizziness or otalgia. He had a left-side grade VI (House and Brackmann) facial palsy. Audiometry revealed normal hearing thresholds in conversation area bilaterally. CT imaging demonstrated a tumor at the left first genu of the facial nerve with expansion to the cochlea wall and middle skull base. MRI imaging demonstrated a centrally enhancing lesion measuring 5 mm x 10 mm in the geniculate ganglion. The tumor was totally removed by the middle cranial fossa approach. At the time of surgery the facial nerve was destroyed by the tumor in the geniculate ganglion. Histopathological examination diagnosed a hemangioma.

A colloid cyst, also called a neuroepithelial cyst, is a slow-growing, benign tumor that occurs in the anterior third ventricle. The cyst typically blocks the foramen of Monro, causing obstructive hydrocephalus involving only the lateral ventricles. The most common presenting sign and symptom of a colloid cyst is headache. Less common presenting signs and symptoms include nausea, vomiting, memory loss, mental status changes, gait disorder, and visual disturbances. Surgical resection is the recommended treatment. Meticulous baseline and ongoing neurological assessments are of paramount importance in the care of a patient with a colloid cyst to promote optimal patient outcomes.

The inverted papilloma is an uncommon unilateral nasosinusal benign tumor. The clinical picture presents nonspecific signs and symptoms, such as unilateral nasal obstruction, anosmia and headache. The diagnosis is established by anamnesis, physical exam, computed tomography and magnetic resonance imaging. Treatment is essentially surgical. This report has the objective of presenting an uncommon bilateral inverted nasal papilloma and making a literature review.

Intraosseous cavernous hemangioma is rarely located in the calvarium. This benign tumor, arising from the intrinsic vasculature of bone, grows slowly over a period of years before it causes symptoms such as headaches or localized compression. We report here the case of a 27-year-old man, who presented with multiple calvarial cavernous hemangiomas associated with several hepatic hemangiomas. The patient had a family history of the disease, and is only the second case of multiple calvarial cavernous hemangiomas reported in the literature. The clinical, radiological and therapeutic aspects of this rare entity are also discussed.

Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle has been identified as a novel and distinctive type of primary central nervous system neoplasm. In this report, we present a case with RGNT arising from the right cerebellar hemisphere. A 30-year-old female patient complained of headache for a five-year duration. Preoperative MRI revealed a well-circumscribed, cystic-solid lesion with hypo-intensity on T1-weighted image, hyper-intensity on T2-weighted image, and significant dot-like enhancement after IV contrast. Gross total resection was achieved in this case via suboccipital retro-sigmoidal approach, and RGNT was confirmed in the final histopathological diagnosis. RGNT of the fourth ventricle is a rare, benign tumor with an excellent prognosis. Operation is recommended as the prior protocol of treatment, and the follow-up MRI is necessary to evaluate the long-term prognostic effects. Currently, only one case of progression or recurrence has been reported in the postoperative course.
