Conus medullaris syndrome vs. Cauda equina syndrome

Both of these are orthopedic/neurosurgical emergencies! But in general, CM syndrome is more severe than CE syndrome.

Here's a comparison between the two...

Apraxia vs autotopagnosia

Hello Awesomites !

Here we will discuss two from many parietal lobe lesion.

Inability to carry out well organized voluntary movement correctly.
Despite motor, sensory & coordinated functions are not significantly impaired.

Ideomotor : It is a type of apraxia.
Patient performs the task but makes errors; there is a common tendency to substitute a body part for an object.
Abnormalities of perception of sensation despite normal sensory pathways.
Visual & body perception are impaired in parietal lobe lesions 

Agnosia of body scheme or autotopagnosia
Inability to locate, identify & orient one’s body parts.

Suppose while on rounds in neurology ward:- You see a patient brushing his knee early morning.(according to above discussion)

Apraxia -Patient has forgotten how to use toothbrush.Brushing knee as a toothbrush rather than pretending to hold one.
Autotopagnosia- the patient has forgotten the body part itself.

In either case localisation of lesion is PARIETAL LOBE.

Isn't the interpretation of one neurological sign seems interesting?

Below is the link which is very descriptive and I came across it while reading more on this topic.
Happy studying !

Types of Sphenoid Sinues.

Hello Guy's!

Here's a sneak peek into the world of Neurosurgery!

In cases of Pituitary Adenomas, the general surgical approach is a TransNasal TransSphenoidal Approach for the excision of the lesion.

To know the type of sphenoid sinus is an important step in the pre-operative planning for the surgery. It also helps in estimating the site where we are most likely to encounter the tumor and the pituitary gland.

Hamburger classified 3 types of pneumatization based on its relationship to the sella turcica.

1)Conchal (rudimentary or absent sphenoid sinus)

2)Presellar (a posterior sphenoid sinus wall that is separated from sella by thick bone).

3)Sellar (a posterior sphenoid sinus wall that is adjacent to sella).

That's all for now... Time to Scrub.

Difference Between Solitary and Singular Brain Metastasis.

Hello Guys!
So we were operating on a metastatic brain lesion the other day when My Consultant happened to ask me the question-  " What is the difference between Solitary and Singular Brain Metastasis?" Well I happened to have a vague idea and managed to blabber something, the actual definition goes as-
• A solitary brain metastasis is defined as the only known metastasis of a tumour in the whole body which happens to be
localised in the central nervous system.
• A singular brain metastasis is defined as a single cerebral metastasis with additional metastases in other organ systems.
Well it's a small nugget, may save you some embarrassing moments.
