Pineal/germ cell tumors and pineal parenchymal tumors.

Introduction: Pineal region tumors (PRTs) are tumors arising from the pineal gland and the paraspinal structures. These tumors are rare and heterogeneous that account for 2.8-10.

Surgical Treatment of Congenital Dermal Sinus: An Experience of 56 Cases.

Objective: This study aims to assess the impact of early diagnosis and surgery on children with congenital dermal sinus, investigate the relationship between MRI findings and extent of surgical exploration, and summarize our clinical experience with the surgical management in cases with central nervous system (CNS) infection.

Methods: The skin features, preoperative MRI images, intraoperative findings, postoperative pathological characteristics, and prognoses of 56 children with congenital dermal sinus were analyzed retrospectively.

Results: All the children had a pinpoint ostium in the skin, and 52 out of the 56 children (92.

Whole spine MRI is not required in investigating uncomplicated paediatric lumbosacral lipoma. A retrospective single-institution review.

Purpose: Lumbosacral lipoma (LSL) is a severe occult spinal dysraphism, frequently associated with neurological, urological and orthopaedic complications. Whole spine imaging is typically performed to identify concomitant, but spatially separate, congenital anomalies. Our hypothesis: the incidence of additional, clinically significant abnormalities of the neuraxis is low; thus, imaging should be optimised at the lumbosacral region.

Encephalocraniocutaneous lipomatosis: A case report with review of literature.

Encephalocraniocutaneous lipomatosis (ECCL) or Haberland syndrome is an uncommon sporadic neurocutaneous syndrome of unknown origin. The rarity and common ignorance of the condition often makes diagnosis difficult. The hallmark of this syndrome is the triad of skin, ocular and central nervous system (CNS) involvement and includes a long list of combination of conditions.

Long standing lumbosacral dermoid tumor and intracranial fat droplet dissemination: A case report.

Background: Dermoid tumors are slow growing, benign CNS lesions.

Case Description: This case study concerns a 29-year-old female with a 6-year history of lower extremity paresthesias attributed to magnetic resonance (MR)/computed tomography (CT) documented intradural dermoid tumor that extended from L1 to S1. On MR, it was hypointense on T1, hyperintense on T2, and did not enhance with gadolinium.

Analysis of the growth pattern of a dermoid cyst.

Dermoid cysts are rare lesions of the CNS with a slow rate of growth. For this reason, they are rarely discovered during infancy. Although benign, these cysts may be associated with devastating complications due to mass effect or meningitis.

Intra-axial CNS dermoid cyst.

Intracranial dermoid cysts are rare tumors. They constitute 0.3% of intracranial tumors.

Intradural dermoid cyst located on the ventral surface of the brainstem in a child.

Background: Dermoid cysts are very rare neoplasms in the CNS. The unusual neuroimaging signs and surgical treatment of the tumor are concerned in this case report.

Case Description: A 9-year-old boy complained of slight headache for 2 months, but complete physical examination showed no neurologic deficits on his admission.

In vivo proton magnetic resonance spectroscopy of human spinal mass lesions.

Objective: To observe metabolic differences between spinal tumor and other diseases in human spinal mass lesions, in vivo 1H magnetic resonance spectroscopy (MRS) was attempted to obtain metabolic signals in patients with various spinal mass lesions.

Methods: 1H nuclear magnetic resonance (NMR) spectra were obtained from 14 patients before surgery using a receive-only surface coil on a 1.5 T clinical magnetic resonance imaging (MRI) unit.

Meningitis due to Staphylococcus aureus in children.

Meningitis due to Staphylococcus aureus is uncommon, occurring primarily in patients with known preexisting abnormalities of the CNS (including patients who have undergone previous neurosurgery or trauma). We reviewed our experience with meningitis due to S. aureus in children seen at two medical centers.
