Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant embryonal central nervous system tumor commonly affecting children <3 years of age. It roughly constitutes 1%-2% of all pediatric central nervous system tumors. Recent data show that it is the most common malignant central nervous system tumor in children <6 months of age. Management of this aggressive tumor is associated with a myriad of diagnostic and therapeutic challenges. On the basis of radiology and histopathology alone, distinction of AT/RT from medulloblastoma or primitive neuroectodermal tumor is difficult, and hence this tumor has been commonly misdiagnosed as primitive neuroectodermal tumor for decades...

Although neurological features are commonly encountered in Whipple's disease (WD), presentation with purely neurologic patterns is uncommon. Exclusive confinement to the central nervous system (CNS) is extremely rare. In these cases, the development of isolated cerebral mass is exceptional. In the present paper, the authors describe a case of a 68-year-old man who presented with partial seizures. The neurological examination was normal. The imaging showed a cystic lesion. This tumor-like lesion was removed by performing frontal craniotomy...

BACKGROUND: Neurenteric cysts are rare central nervous system lesions derived from an endodermal origin. There is no consensus concerning pathogenesis due to the paucity of occurrences. The authors report their immunohistochemical study of ten cases with neurenteric cysts and postulate its pathogenesis. METHOD: Ten patients underwent surgical treatment for neurenteric cysts from 1995 to 2015. We retrospectively reviewed clinical, radiological, operative, and pathological findings for these patients...

Schwannomas are benign nerve sheath tumors that may arise along the complex course of the cranial nerves (CNs), anywhere in the head and neck. Sound knowledge of the CN anatomy and imaging features of schwannomas is paramount for making the correct diagnosis. In this article, we review approaches to diagnosing CN schwannomas by describing their imaging characteristics and the associated clinical presentations. Relevant anatomic considerations are highlighted by using illustrative examples and key differential diagnoses categorized according to regions, which include the anterior skull base, orbit, cavernous sinus, basal cisterns, and neck...

Neurocysticercosis is an important parasitic disease of the central nervous system and constitutes a public health challenge for most of the developing world. Radiological findings may be quite variable. A 50 year old man presented with recent onset generalized tonic-clonic seizures. CT scan revealed a lobulated cystic lesion in the right fronto-temporal lobe compressing the lateral and third ventricle and upper brainstem. Clinico-radiological diagnosis of right fronto-temporal space occupying lesion with possibility of cystic glioma was made...

We describe two rare cases of frontal cystic lesions presenting with symptoms and signs of raised intracranial pressure. Both had a preoperative diagnosis of an arachnoid cyst and were subjected to a craniotomy with marsupialization of the cyst. However, the histology confirmed them to be an endodermal cyst (EC) on both occasions. Both the patients have been closely followed with no recurrence of symptoms. ECs of the central nervous system are usually reported in the spinal canal, mid-line posterior fossa, and the suprasellar regions...

We aimed to evaluate the clinical and pathologic features of two common medical illnesses and their appropriate workup and pathognomonic findings. A 57-year-old white male presented with a new onset expressive aphasia while traveling abroad. He was evaluated at an outside facility and underwent workup for a stroke. The evaluation included a CT and MRI of the brain demonstrating three new enhancing lesions, the largest of which was a 2.5 cm ring-enhancing cystic lesion. A CT of the chest noted a 4-cm cystic thyroid lesion that was diagnosed as a thyroid cancer with brain metastases...

We report an incidental case of intravascular large B-cell lymphoma (IVLBCL) coexisting with an ovarian carcinoma in a 76-year-old woman. She visited our hospital with difficulty in defecation. Magnetic resonance imaging and computerized tomography scan revealed a solid and cystic mass probably arising from the left ovary. Gross examination of the tumor obtained by an exploratory surgery showed a solid area in a simple cyst. The ovarian tumor was diagnosed as a high-grade serous carcinoma (HGSC). Early in the post-operative course, this patient developed fever of unknown origin with central nervous system manifestations...

BACKGROUND: Meckel-Gruber syndrome is a ciliopathy, a lethal autosomal recessive disorder that occurs in all races and ethnicities; it is characterized by central nervous system abnormalities, resulting in mental retardation, bilateral renal cystic dysplasia and malformations of hands and feet. To date there have been only about 200 cases reported worldwide. It is a disease with a recurrence rate of 25% whose most reliable method for diagnosis is prenatal ultrasound. The mortality rate is 100% and in view of the high index of recurrence, subsequent pregnancies should be investigated appropriately with genetic counseling...

Teratomas of the central nervous system are rare and are frequently found in children and young adults. Cystic teratomas found in infancy is a well-recognized but infrequent entity. Intracranial teratomas,like teratomas in general, tend to arise from midline structures such as the pineal gland, but has rarely been found in the third ventricle. We report a rare case of a 6-month-old infant with a mature cystic teratoma of the third ventricle with a review of literatures.

Cystic dysraphism of the cervical and upper thoracic spine is very rare. It differs from the much more common lumbosacral dysraphism in appearance and structure, and usually portends a better prognosis due to lack of functional neurological tissue in the dysraphic sac and absent or less severe intracranial anomalies. There is ambiguity in the literature regarding terminology because of the paucity of cases. We present cases of the most common type of cervicothoracic cystic dysraphism and emphasize differences from lumbosacral myelomeningocele...

BACKGROUND: Phosphodiesterase 5 inhibitors (PDE5-Is) sildenafil, vardenafil, tadalafil and the recently approved avanafil represent the first-line choice for both on-demand and chronic treatment of erectile dysfunction (ED). In addition to this, sildenafil and tadalafil, have also been approved for the treatment of pulmonary arterial hypertension. Due to its expression and localization in many tissues, PDE5 and its regulation has been reported to be involved in several other diseases...

For patients with inoperable salivary gland malignancy, radiation therapy has significant limitations but has been the mainstay of treatment. With standard photon radiation (X-rays), the 10-year loco-regional control (LRC) and overall survival rates are only ∼25%. Neutron radiation has potential biological advantages over photon radiation because it causes increased DNA damage, and studies of patients with inoperable salivary gland malignancy have shown improved 6-year LRC and overall survival of ∼60%. However, neutron radiation may also increase the risk of late toxicities, especially central nervous system toxicities after treatment of tumors involving the base of the skull...
