So sorry you are having pain...I will try to help with the definitions of disc bulge and herniation as best I can...
Desiccation - loss of disk water
Disk bulge - circumferential enlargement of the disk contour in a symmetric fashion
Protrusion - a bulging disk that is eccentric to one side but < 3 mm beyond vertebral margin
Herniation - disk protrusion that extends more than 3 mm beyond the vertebral margin
Extruded disk - extension of nucleus pulposus through the anulus into the epidural space
Free fragment - epidural fragment of disk no longer attached to the parent disk

Definition: A 'disc bulge' is a word used to describe findings seen on a MRI study of the spinal discs. The spinal discs are soft cushions that rest between the bones of the spine, the vertebrae. When a disc is damaged, it may herniate, or push out, against the spinal cord and spinal nerves.
A 'disc bulge' is a word commonly used to describe a slight outpouching of the disc. The words 'disc bulge' imply that the disc appears symmetric with a small amount of outpouching, and no significant herniation.
Disc bulging is often an incidental finding on MRI. As people age, disc bulges are commonly seen on MRI. Disc bulges can be seen in patients with no symptoms of back problems, especially in patients over the age of 40. A physical examination can help distinguish a disc bulge that is causing problems from a disc bulge that is an incidental finding.

A disc protrusion
generally refers to a broad-based or slightly asymmetric bulging of the disc with an intact annulus and reflects disc degeneration (see below). Sometimes you may even see the term focal disc protrusion, which usually means the same thing as a disc herniation.
In your lumbar spine they describe the scoliosis as being dextroscoliosis
which simply stated means this:
Scoliosis is never normal. It is considered scoliosis when the amount of curvature of the spine is > 10 degrees. It usually is due to congenital malformations or muscular disease. We categorize it by age of onset. The pattern is named for the locations (e.g. cervical, thoracic, or lumbar) and the side of the convexity (levo is where the convexity is to left and dextro is to the right). The time of most rapid curvature is just before and during puberty. There is usually little progression of scoliosis after puberty, unless the patient has muscle disease and the disease progresses. Curves < 20 degrees usually do not cause health problems but anything over 40 degrees usually requires surgery.
About Spina Bifata:
Spina bifida occulta is common. Two studies undertaken in Great Britain in the mid 1980s suggest that 22% or 23% of people have spina bifida occulta. Even though there is a very slightly increased chance of a slipped disc, very few people with spina bifida occulta will ever have any problems because of it. If a person has no symptoms from spina bifida occulta as a child, then it is unlikely that they will have any as an adult.
Most people will not even be aware that they have spina bifida occulta unless it shows up on an X-ray which they have for some unrelated reason. It is usually just a small part of one vertebra low in the back which is missing. See the diagrams below that show cross sections of one vertebra.
In your lumbar spine they also talk about moderate bilateral neural foraminal stenoses...
An explanation of neural formainal stenosis:
Neural foraminal narrowing is a common result of disc degeneration. Spinal nerves pass through an opening in the spinal column known as the foramen. The process of disc degeneration or bulging causes the foramen to become narrower. Once the foraminal opening reaches a point of compressing the nerves inside the spinal column, pain, numbness, tingling, and muscle weakness often occur.
Other possible causes of neural foraminal narrowing include rheumatoid arthritis, osteoarthritis, chronic meningitis, tumors, and neurofibromas. Any type of neural involvement should be identified and treated to limit the amount of permanent damage that can result.
The most common method of confirming a diagnosis of neural foraminal narrowing involves some type of diagnostic imaging--MRI, CAT scan, etc.
Radiculopathy as well as sciatica is the radiation of pain to the lower extremity. It is the result of pressure on a nerve root, usually by a herniated lumbar disc. Besides a disc, other sources of compression may be arthritic spurs, spinal stenosis and foraminal stenosis.
Lumbar nerve roots, their distributions, and the discs which commonly affect them
L1 sciatica: T12/L1 disc; L1 root supplies sensation to the thigh and the anterior scrotal or anterior labial branches, as the ilioinguinal nerve. The lumbar disc which would typically affect this nerve is the T12/L1 disc centrally, or the L1/L2 disc laterally in the neural foramen.
L2 sciatica: L1/L2 disc; L2 root supplies sensation to the front and side of the thigh, as the lateral femoral cutaneous nerve. The lumbar disc which would typically affect this nerve is the L1/L2 disc centrally, or the L2/L3 disc laterally in the neural foramen.
L3 sciatica: L2/L3 disc; L3 root supplies sensation to the front and side of the thigh, as the lateral femoral cutaneous nerve. The lumbar disc which would typically affect this nerve is the L2/L3 disc centrally, or the L3/L4 disc laterally in the neural foramen.
L4 sciatica: L3/L4 disc: L4 root supplies sensation to the anterior lower thigh. The lumbar disc which would typically affect this nerve is the L3/L4 disc centrally, or the L4/L5 disc laterally in the neural foramen.
L5 sciatica: L4/L5 disc: L5 root supplies sensation to the top of the foot and the great toe. The lumbar disc which would typically affect this nerve is the L4/L5 disc centrally, or the L5/S1 disc laterally in the neural foramen.
S1 sciatica: L5/Sa disc: S1 root supplies sensation to the outside of the foot, and the small toe. The lumbar disc which would typically affect this nerve is the L5/S1 centrally. There is no S1/S2 disc to herniate laterally to affect it.
S2 sciatica: no disc to affect this root individually. Supplies rectal sensation.
S3 sciatica: no disc to affect this root individually. Supplies rectal sensation.
S4 sciatica: no disc to affect this root individually. Supplies rectal sensation.
I do not think your spinal problems are related to Gorlin Syndrome...I would think they are independent of each other, but I am not a doctor...just a simple layperson with an interest in all of this and a fellow sufferer of spinal problems....
Gorlin Syndrome is a condition which can cause many different signs and symptoms. Patients can present to different specialists, depending on the first sign of the syndrome. A study in the North West of England showed that it affects 1 in 55,600 people.
The syndrome has been given several different names:
nevoid basal cell carcinoma syndrome
basal cell nevus syndrome
epitheliomatose multiple generalisee,
hereditary cutaneomandibular polyoncosis,
multiple basalioma syndrome,
The syndrome has been given several names in the medical literature because patients with particular problems were described by the specialist looking after them. The suggested name of the condition then mirrored the speciality of the doctor writing the report. Professor Gorlin suggested that it might best be called the nevoid basal cell carcinoma syndrome, although 10% of adults do not develop basal cell carcinomas (BCCs). Rather than focus on one feature of the condition, it may be better to use the title of Gorlin syndrome, in recognition of Professor Robert Gorlin's contributions, especially as parents and patients prefer not to have a name which contains the word "carcinoma".

Hope this helps you to understand better....
