Bump on dogs skull getting bigger :(

[Doglover77]

I have a Rotti x French mastiff who has always had a protruding lump on the centre-top of his head. I believe it's called the "occiput". Recently it appears much bigger. He's 3.

has anyone had this happen? 

MY thought would be perhaps he has muscle/fat wasting away from his head/face although it's not noticeable and the rest of him is chunky. No jaw symptoms.

he has had 2 seizures in 4 months and been to specialists and had full bloods but haven't yet had MRI/lumbar puncture done so not sure if it's related with this bump growth

What opinion has has your vet mentioned about the lump?
Has his head been x-rayed to check for skull fractures?

The occiput shouldn’t grow at that age so I would be worried there was something else going on. There are conditions that affect the muscles of the head, but I suppose it could also be some kind of tumour-definitely something to raise with your vet.

Thanks heaps. My boy had a muscle biopsy taken and the pathology report came back as MMM. He's on steroids in addition to his seizure meds...the 2 issues not reportedly connected. Early days but remaining hopeful. It seems we caught it early before the Jaw muscles were affected, luckily

He is lucky he had an attentive owner who noticed so early. Good luck with it.

Thanks so much. With my last boy I noticed Cushing at an early stage where the vet thought I was crazy for presenting....but he was 9. This boy is 3 but I'll fight with all I have to do all I can. I am worried he's not on a high enough dose of prednisone tho...30mg morning and 30mg night for a 56kg dog. From reading up he should be on 2mg/kg not 1mg/kg but I'll follow vet advice for now and watch closely

so glad that you are so observant.. I hear you about the vet thinking you are crazy.. i had a dog who was hypothyroid.. he was a gigantic walking list of symptoms.  and his previous vet had been treating an eye problem with pred which was making everything worse.   once i lured vet out to take bloods for testing  and the lad was started on  meds all returned to almost normal.  Hope all goes spectacularly well with your  boy.
