ABSTRACT are benign, bone-forming tumours located within bones or developing on them. In the head and neck region they are commonly seen in the frontoethmoidal region. Occipital osteomas are very rare tumours. They are often asymptomatic and are incidentally found on radiological investigations. The main clinical symptom is of varying intensity and quality, though some patients may complain of dizziness in cases of large tumours. We describe here a case of occipital in a female, arising from the inner table. It was asymptomatic and osteoma was removed for cosmetic purpose. CT scan is a must to confirm the diagnosis, the involvement of the inner table as well as to look for any intracranial extent of the osteoma.

A careful search of the English literature failed to reveal any previously reported case of occipital osteoma. Most often they are localized on sutures. Except for cortical lesions that are seen initially as cosmetic deformities, these tumours are usually unsuspected roentgenographic findings. The main clinical symptom is headache of varying intensity and quality, and in most cases not proportional to the size of the osteoma, which ranges from the size of a pepper bean to the size of a child’s head. In addition to headache, there can be sensitivity to pressure in the region of the or dizziness. Treatment is indicated for symptomatic osteomas.

CONCLUSION

Osteomas are rarely rarely originate from the flat bones of the skull and their management depends upon the symptomology. Small osteomas are harmless and can be left as such; surgery is indicated only in cases of cosmetic problem. Large osteomas causing dizziness, headache and intracranial extension or compression, need excision. Differential diagnosis of other bony tumours should also be kept in while dealing with Figure 2: Excised specimen of the osteoma them.

ABSTRACT A case report of recurrent appendicitis, 40 years after appendectomy is presented. In the present case, we failed to diagnose stump appendicitis preoperatively due to the existence of the lipohyperplasia of the ileocecal valve which showed features of ileocolic intussusception causing right lower abdominal pain and nausea. of the appendiceal stump after appendectomy is a rare complication, but in the assessment of patients with lower quadrant abdominal pain who have previously undergone appendectomies, stump appendicitis should be considered.
