Solitary fibrous tumors/hemangiopericytomas (SFTs/HPCs) are rare in the central nervous system and intraventricular SFTs/HPCs are even rarer. We present a clinical case of SFT/HPC that was located in the fourth ventricle and performed a literature review of radiological findings of SFT/HPC. The patient was a 52-year-old man who presented to our hospital with dizziness and progressive weakness in his left extremities. Computed tomography and magnetic resonance imaging showed an irregular-shaped mass in the fourth ventricle. The upper anterior and lower posterior parts of the mass showed different densities and signal intensities, which formed a black and white sign. The upper anterior and lower posterior parts of the mass were enhanced to different degrees, and showed heterogeneous reversed enhancement. The patient underwent surgical resection and the mass was histologically confirmed to be an SFT/HPC. SFTs/HPCs of the fourth ventricle are rare, but show characteristic radiological presentations. In the present case, we observed a solid mass with flow voids, black and white sign, and heterogeneously reversed enhancement in the fourth ventricle. Collectively, these radiological features suggested the diagnosis of SFT/HPC.

Solitary fibrous tumor is a very rare mesenchymal tumor that occurs mostly in the pleura, and there are few reported cases of a presence in the central nervous system, particularly in the cerebellum. In 2016, the WHO classified solitary fibrous tumors into grade I. In this article, we present a case of malignant solitary fibrous tumor recurring 8 years after surgery in a 63-year-old male. Magnetic resonance imaging showed low to intermediate mixed signal intensity on T1W1. Immunohistochemical staining positivity for Vimentin, CD99, CD34 and Bcl-2, it is consistent with the immunohistochemical characteristics of solitary fibrous tumor. We resected the patient’s tumor, and the patient was followed up for 3 months with no signs of recurrence. Solitary fibrous tumors are very rare in the central nervous system. Immunohistochemical staining positivity for CD34 and Bcl-2 is strongly expressed in most solitary fibrous tumor. Surgical resection is the preferred treatment. Due to the small number of cases, the biological behavior and prognosis of this tumor need to be further explored.

Phakomatoses are a group of more than 30 entities with an inheritance pattern that primarily affects the central nervous system, skin, viscera and connective tissue. The aim of this paper is to make an educational review of the most common radiological findings on phakomatoses through the iconography of the cases collected in our magnetic resonance imaging (MRI) and computer tomography (CT) units over the last ten years. Also, we describe and illustrate by these techniques the main features of the most common entities within the wide spectrum of diseases. As highly variable and age dependent, imaging techniques have an important role in the diagnosis and follow-up of these patients. Increased awareness for the need to implement and conduct screening programs could be considered as a solution to prevent late diagnosis and to treat the patients in early stages of disease.

Histopathological Grading

Ectopic brain anaplastic ependymomas with no connection to the ventricles are rare. We present a rare case of a 25-year-old male who presented with generalized convulsions. Computed tomography (CT), Magnetic Resonance Imaging (MRI), and magnetic resonance spectroscopy (MRS) showed characters of an intra- and extra-axial lesion. Intraoperatively, the lesion was a cortical solid mass that had no connections to the dura or to the ventricle. The histological diagnosis showed an anaplastic ependymoma with WHO grade III with distinctive desmoplasia. A literature review of ectopic anaplastic ependymomas regarding their clinical presentations, management, and prognostic factors was performed. There is a need to establish a clinically based histopathological grading system for anaplastic ependymomas. Ectopic anaplastic ependymomas should be included in the preoperative differential diagnosis.

✓ Subependymomas of the fourth ventricle are generally considered incidental postmortem findings, and have received scant attention from neurosurgeons. The authors present a surgical series of 12 cases of this disorder diagnosed over a 13-year period. The clinical and radiological findings were reviewed and correlations made with pathological studies. The subependymoma is a histologically benign tumor that tends to be calcified. It has a predilection for the fourth ventricle and a peak incidence in the fifth decade of life. It is usually of considerable size with extensive attachment at the time of its detection, and is associated with significant surgical morbidity. The authors believe that magnetic resonance imaging may be the best method of investigation. Intraoperative disturbance of circulatory or respiratory control should suggest to the surgeon that the operation be abandoned. A laser or ultrasonic aspirator may be very helpful in removing these tumors. Postoperative care must include monitoring for apnea.

We present a case of a 65-year-old female with glioblastoma of the spinal cord, which disseminated to an intracranial lesion. Magnetic resonance imaging revealed diffuse swelling at levels C1 to 4, which was pathologically consistent with glioblastoma, and right side pontine parenchyma mass. The patient died after seven weeks of hospitalization. The confirmed diagnosis of glioblastomas was obtained as a result of autopsy. Spinal glioblastomas are rare lesions of the central nervous system with a prognosis as poor as that of their intracranial counterpart. There have been only nine reports in English since 1990, including this case in Japan.

A 54-year-old female presented with a two year history of progressive headaches and upper neck pain. The headaches were worse with coughing and bending. Neurological examination was unremarkable including a normal cranial nerve examination. There was no papilloedema. A computed tomogram (CT) demonstrated a midline, posterior fossa, partly fatty, partly solid mass (Figure 1). Magnetic resonance imaging (MRI) demonstrated a mixed fatty, solid mass arising from the fourth ventricle and extending downward below the foramen magnum to the C1 level (Figure 2). The solid portions demonstrated enhancement. In addition, in the lateral right cerebellar hemisphere, there was a second, separate, solid, enhancing mass without any connection to the larger central lesion. A subtotal resection of the tumor was achieved through a suboccipital craniectomy.

✓ The purpose of this paper was to present two cases of secondary trigeminal neuralgia (TN) with an unusual origin and lesion location. In two cases TN was caused by lesions along the course of the trigeminal nerve within the pons and adjacent to the fourth ventricle. Both cases presented with typical TN. Brain magnetic resonance imaging revealed linear or wedge-shaped lesions adjacent to the fourth ventricle, extending anterolaterally and lying along the pathway of the intraaxial trigeminal fibers. The involvement of the nucleus of the spinal trigeminal tract and of the principal sensory trigeminal nucleus with segmental demyelination are suggested as possible causes for trigeminal pain in these cases. It is postulated that these lesions are the result of an old viral neuritis. The patients underwent gamma knife radiosurgery and their clinical responses have been encouraging to date.

AbstractCryptococcosis is a fungal infection that is rarely reported in patients without human immunodeficiency virus (HIV) infection, especially when the central nervous system (CNS) or pulmonary system is not involved. We report a case of isolated colonic cryptococcosis without disseminated disease in a 64-year-old immunocompetent woman without HIV infection who presented with chronic diarrhea and no episodes of fever or weight loss. The diagnosis was based on histopathology examination. Furthermore, we performed a literature review showing that few reports have been published so far and in the case of colonic cryptococcal infection, the prognosis is favorable among HIV-uninfected patients.
