A case report of lobular intradural extramedullary capillary hemangioma in a 14-year-old patient: resection and reconstruction.

Background: Intradural, extramedullary capillary hemangiomas of the cauda equina are exceedingly rare malformations arising from the endothelial cells of the nervous system vasculature. Roughly 20 cases have been reported in the literature, with the youngest and only pediatric case being in a 17-year-old patient. We report the youngest case of intradural extramedullary capillary hemangioma of the cauda equina in a 14-year-old patient.

Oncogenic GOPC-ROS1 Fusion Identified in a Congenital Glioblastoma Case.

Congenital glioblastoma (GBM) is a rare brain tumor of infancy. While histologically they resemble pediatric and adult GBM, growing evidence suggests a distinct molecular profile. We report the case of a 7-day-old infant female with congenital GBM found to harbor a GOPC-ROS1 fusion.

Bilateral Proximal Tibia Stress Fractures through Persistent Physes.

Introduction: Fatigue fractures are stress fractures resulting from repetitive trauma in areas of stress concentration. Prior case reports and studies have described stress fractures through persistent physes about the olecranon and distal fibula, as evidenced by hyaline cartilage on histologic analysis. However, there have been no documented proximal tibia stress fractures through persistent physes.

A Unique Case of Muscle-Invasive Metastatic Breast Cancer Mimicking Myositis.

Breast cancer rarely metastasizes to the muscles, and it is even more unusual for this phenomenon to result in airway compromise. We present a unique case of an 84-year-old female who presented with neck swelling and upper airway obstruction due to metastatic breast cancer invading the sternocleidomastoid muscles. After establishing the diagnosis and discussing possible treatment options, the patient elected for antiestrogen therapy, palliative tracheostomy, radiation therapy, and hospice services.

Intracranial neurenteric cyst mimicking an ependymoma: imaging features, pathologic correlation and review of literature.

We present a case of a 57-year-old female with four-months of diplopia and vertigo. MRI revealed a mixed cystic and solid partially enhancing lesion of the 4th ventricle, foramen of Luschka and cerebellopontine angle. Preoperative differential diagnosis favored ependymoma.

Cytomegalovirus in the human dentate gyrus and its impact on neural progenitor cells: report of two cases.

Congenital cytomegalovirus (CMV) infection in the 2 and 3 trimester results in catastrophic CNS abnormalities. This susceptibility is thought to result from the high proportion of neural stem cells in the developing brain. In immunocompromised adults, CNS infection by CMV preferentially affects ependymal surfaces, from where it expands to involve the parenchyma.

Delayed Diagnosis of TSH-Secreting Adenoma Attributed to Worsening Post-Traumatic Stress Disorder Symptoms in a Military Veteran Because of Provider Anchoring Bias.

Introduction: Anchoring bias occurs when clinicians hold on to previously known information about a patient, with failure to consider the full realm of possibilities to explain new findings. We present a case of delayed diagnosis of thyroid-stimulating-hormone-secreting pituitary adenoma (TSHoma), a rare disorder, in a military veteran whose symptoms were misconstrued as being caused from worsening of his prior diagnosis of post-traumatic stress disorder (PTSD). Anchoring bias in this case led to 2-year delay in the correct diagnosis.

A Case of Undiagnosed Craniopharyngioma in an Army Mechanic.

Primary care providers are often the initial evaluators of soldiers presenting with acute eye complaints. It is crucial for these providers to master performing the basic eye examination with a systematic approach. Obtaining a thorough history is an important first step to the eye examination, but providers need to be careful not to narrow the diagnosis solely based on the history.

Clinical Outcome of Silent Subtype III Pituitary Adenomas Diagnosed by Immunohistochemistry.

Silent subtype III pituitary adenomas (SS-3) are nonfunctioning radiosensitive adenomas that may be associated with an increased risk of recurrence and invasion. The features that have been proposed to be diagnostically important are identifiable by electron microscopy (EM) and include an enlarged Golgi apparatus, along with several other ultrastructural features. The often limited availability of EM and the uncertainty about the relative importance of individual features pose practical challenges to the diagnosis.

Common pediatric cerebellar tumors: correlation between cell densities and apparent diffusion coefficient metrics.

Purpose: To test whether there is correlation between cell densities and apparent diffusion coefficient (ADC) metrics of common pediatric cerebellar tumors.

Materials And Methods: This study was reviewed for issues of patient safety and confidentiality and was approved by the Institutional Review Board of the University of Texas Southwestern Medical Center and was compliant with HIPAA. The need for informed consent was waived.

Intracranial phosphaturic mesenchymal tumors: report of 2 cases.

Hypophosphatemia with osteomalacia may be due to a neoplasm that produces fibroblast growth factor 23 (FGF-23), which inhibits phosphate reabsorption in the kidneys. Most of these tumors occur in bone or soft tissue and occasionally in the head, although intracranial occurrence is very rare. This report describes a tumor that caused hypophosphatemia and osteomalacia and was located entirely in the right anterior cranial fossa.

Exercise-associated numbness and tingling in the legs.

A 52-year-old physically active man with a medical history of coronary artery disease, hypertension, and hyperlipidemia presented with numbness and tingling in the legs. His symptoms were intermittent initially, triggered by running or playing soccer and relieved by rest. Symptoms progressed during 1 year.

The application of split-thickness skin graft as an autogenous arterial conduit in a goat (Capra hircus) model.

Adequate autogenous vein is often the limiting factor in achieving a successful infrainguinal bypass. Attempts have been made to find alternative conduits; however, these alternatives have demonstrated inferior patency rates. We attempt to show that a split-thickness skin graft conduit provides a feasible autogenous arterial conduit.
