Intracranial space occupying lesions are tumors or abscesses present within the cranium or skull.They are one of the three types of lesions that can occur; the other two are vascular (thrombosis, emboli etc) and lesions due to trauma.
Toxoplasmosis (caused by protozoa Toxoplasma Gondii) is an example of a space occupying lesion of the brain. It is one of the infestation of HIV when it turns into AIDS in the central nervous system.
Substantial physical lesions, e.g. neoplasm, hemorrhage, granuloma, which occupy space; the effect is more significant if the lesion is within a space confined by bone, e.g. thorax, cranium, bone marrow cavity.
Cecal mass is a space occupying lesion that involves the first part (cecum) of the colon. It can be benign or cancerous.
I'm thinking it probably stands for Space Occupying Lesion. It's a generic phrase used to describe a morphological abnormality that is discrete and distinct from the normal tissue.
Matter is anything occupying space.
Matter is anything having mass and occupying space (has volume).
Based on this definition: "Cecal mass is a space occupying lesion that involves the first part (cecum) of the colon. It can be benign or cancerous," I would code 568.89. This is the code in the alphabetic index under "lesion, colon." The tabular index does not list "lesion" under this code but it doesn't exclude it, either, so based on the alphabetic index, 568.89 should be acceptable.

Volume
We can't both occupy the space at the same time, move on!
This could be normal (especially if the baby was a pre-term baby). however, points you need to know are: - Usually the anterior fontanelle closes anytime between 8 to 18 months. - Delay beyond the second year, may be an indication of a bone disroder (like rickets) or due to increased intracranial pressure (mass-occupying lesion or simply hydrocephalus)

This is called a tonsillar hernation, where the cerebellum is pushed through the foramen magnum. The extra brain trying to pass through the foramen magnum can cause compression of the medulla, which has serious complications (e.g. stop breathing.) This may be due to a space occupying lesion somewhere else in the brain, or in the cerebellum itself. As the brain cannot expand outwards (due to the hard skull) it expands down (and across where possible). Examples of space occupying lesions include haemorrhage, oedema and tumours.
