Q

Unrelated difficult SBA courtesy of Laz

43-year-old gardener is brought into A&E after having a seizure. His seizure lasts about 2 mins and disappears by itself. He says that this has never happened before and his only health problem has been a persistent headache that has developed over the past 6 months. On examination, a single heavily pigmented skin lesion is noticed on his right forearm. An MRI head scan reveals several lesions in both hemispheres.

What is the most likely diagnosis?

A Neurofibromatosis Type 1

B Meningioma

C Tuberous sclerosis

D Metastases

E Glioblastoma multiforme

A

D Metastases

Melanoma tend to have brain mets

Just because neuro signs and skin lesions doesn’t mean neurofibromatosis

Symptoms suggest space occupying lesions - persistent headaches for 6 months + focal neurological signs: seizures, parasthesia, changes in speech, vision and hearing

Majority of brain tumours are mets

Skin lesion likely to be a melanoma

Gardener means likely to have risk factor of high UV exposure

Glioblastoma multiforme and meningoma tend to be single discrete lesions

Tuberous sclerosis is a hereditary condition that leads to the formation of multiple benign tumours across the body. It is an autosomal dominant condition so most people with tuberous sclerosis will be aware that they have it and will not be presenting at the age of 43.

Neurofibromatosis type 1 tends to cause fewer central nervous system lesions and has more widespread peripheral features, such as neurofibromas, café au lait macules (> 5 is significant), axillary freckling, Lisch nodules and spinal scoliosis.
