Case Summary

46 yof came for syncopal episode. No known neurological hx. MRI will hopefully follow if patient isn't transferred before.

Additional Notable Cases

Axial T1 (image 1) and T1 postcontrast (image 2) show a poorly enhancing solid mass of the posterior fossa. The location and appearance are typical of a medulloblastoma. Medulloblastoma represents the second most common pediatric brain tumor after juvenile pilocytic astrocytoma. They arise from the roof of the fourth ventricle. Other posterior fossa masses include ependymoma, pilocytic astrocytoma, and atypical teratoid/rhabdoid tumors.

Classic brain tumor. What kind is it and what cell is it derived from?

29 years old, female, hydrocephalus. MRI shows a IV ventricule tumor highly suspicious of Choroid Plexus Papilloma. We perform first a CSF derivation, and on a second surgical time a midline suboccipital craniotomy, telovelar approach and gross total resection. Picture 2 shows specimen. Patient remains asymptomatic, this benign tumor has an excellent prognosis.

This case is a 4th ventricle subependymoma. You could sure miss this! I’ll have some additional insights tomorrow.

Trending Cases

A 52-year-old man presented with a 20-minute history of chest pain radiating to the left shoulder and neck, associated with dyspnea and diaphoresis. He had a history of hypertension, long-term smoking, and a sedentary lifestyle. On physical examination, bibasilar crackles were noted on lung auscultation. An electrocardiogram (ECG) was performed in the primary care setting, and the patient was promptly referred to the emergency department.

A 28-year-old woman presented with a 3-day history of intense pruritus over the lower back. She reported no recent travel or exposure to new environments. She cares for a small kennel with approximately eight dogs rescued from the streets. Physical examination revealed multiple small vesicles, some clustered and others scattered, predominantly involving the lumbar region and the left gluteal area.

A 4-month-old male infant presented with skin lesions localized to the chin for the past 3 days. Physical examination revealed multiple small pustules with surrounding inflammatory signs on the chin, along with a few scattered papules on the chest.

Patient in late teens presenting after a collapse, no chest pain, no previous cardiac history, no history of sudden death in family, are there any features in this EKG that would warrant further work-up or is this just a pediatric EKG?
