Teaching NeuroImages: sinus pericranii.

Antonetta Margaretha Gezina Sas, MD Fop van Kooten, PhD An 18-year-old woman was referred for a slowly growing tumor on her scalp, which had been present since her birth. Examination revealed a soft-tissue non-pulsating mass on her scalp (figure 1) which became larger in recumbent position and with Valsalva maneuver. CT showed that almost the entire venous system drained through enlarged pariet...

Case Report: Iatrogenic Seeding of Tumor Cells in Thigh Soft Tissue Upon Surgical Removal of Intracranial Meningioma

Introduction: Meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. It can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. As a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. Trauma and vi...

Teaching NeuroImages: Bruns syndrome caused by intraventricular neurocysticercosis.

A 24-year-old woman presented with 2 months of episodic vertigo, vomiting, and headache triggered by abrupt head movements, lasting from a few minutes to 1 hour. She was asymptomatic between the attacks and had mild gait ataxia on examination. Brain MRI revealed obstructive hydrocephalus and a cystic lesion in the fourth ventricle (figures 1 and 2). Her symptoms subsided after cyst excision; a ...

Slowly Growing Nodule on the Trunk: Cutaneous Granular Cell Tumor

Granular cell tumor (GCT) is a rare benign neoplasm of the skin that accounts for 0.5% of all soft-tissue tumors. The tumor mostly presents with a symptomatic slowly growing solitary nodule and overlying normal skin; therefore, it is not always considered in the differential diagnosis. Here, we report a 58-year-old female patient who presented with a 4-year history of a slowly growing mass, wit...
