Rachman has also tested the effectiveness of this method in treating claustrophobia and found it to decrease fear and negative thoughts/connotations by an average of nearly 75% in his patients. Of the methods he tested in this particular study, this was by far the most significant reduction. Interoceptive exposure
This method attempts to recreate internal physical sensations within a patient in a controlled environment and is a less intense version of in vivo exposure. This was the final method of treatment tested by S.J. Rachman in his 1992 study. It lowered fear and negative thoughts/connotations by about 25%. These numbers did not quite match those of in vivo exposure or cognitive therapy, but still resulted in significant reductions.Other forms of treatment that have also been shown to be reasonably effective are psychoeducation, counter-conditioning, regressive hypnotherapy and breathing re-training. Medications often prescribed to help treat claustrophobia include antidepressants and beta blockers, which help to relieve the heart-pounding symptoms often associated with anxiety attacks. See also

A bone cyst or geode is a cyst that forms in bone. Types include:

Unicameral bone cyst
Aneurysmal bone cyst
Traumatic bone cyst

Diagnosis
On CT scans, bone cysts that have a radiodensity of 20 Hounsfield units (HU) or less, and are osteolytic, tend to be aneurysmal bone cysts.In contrast, intraosseous lipomas have a lower radiodensity of -40 to -60 HU. Treatment and Prevention
Simple (Unicameral) Bone Cyst
Some unicameral bone cysts may spontaneously resolve without medical intervention. Specific treatments are determined based on the size of the cyst, the strength of the bone, medical history, extent of the disease, activity level, symptoms an  individual is experiencing, and  tolerance for specific medications, procedures, or therapies. The types of methods used to treat this type of cyst are curettage and bone grafting, aspiration, steroid injections, and bone marrow injections. Watchful waiting and activity modifications are the most common nonsurgical treatments that will help resolve and help prevent unicameral bone cysts from occurring and reoccurring. Aneurysmal Bone Cyst
Aneurysmal bone cysts can be treated with a variety of different methods. These methods include open curettage and bone grafting with or without adjuvant therapy, cryotherapy, sclerotherapy, ethibloc injections, radionuclide ablation, and selective arterial embolization. En-block resection and reconstruction with strut grafting are the most common treatments and procedures that prevent recurrences of this type of cyst. Traumatic Bone Cyst
The traumatic bone cyst treatment consists of surgical exploration, curettage of the osseous socket and bony walls, subsequent filling with blood, and intralesional steroid injections.
