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.
Molybdenum deficiency refers to the clinical consequences of inadequate supplies of molybdenum in the diet. The amount of molybdenum required is relatively small, and molybdenum deficiency usually does not occur in natural settings. However, it can occur in individuals receiving parenteral nutrition. Signs and symptoms
Descriptions of human molybdenum deficiency are few. A patient receiving prolonged parenteral nutrition acquired a syndrome described as ‘acquired molybdenum deficiency.’ This syndrome, exacerbated by methionine administration, was characterized by high blood methionine, low blood uric acid, and low urinary uric acid and sulfate concentrations. The patient suffered mental disturbances that progressed to a coma. Pathological changes occurring in individuals with a genetic disease that results in a sulfite oxidase (a molybdoenzyme) deficiency include increased plasma and urine sulfite, sulfate, thiosulfate, S-sulfocysteine and taurine; seizures, and brain atrophy/lesions; dislocated lenses; and death at an early age.. Diagnosis
Treatment
300 mcg Ammonium Molybdate per day can bring about recovery of “acquired molybdenum deficiency” [3]
