Pseudotumor cerebri occurs quite rarely in the pediatric population and its clinical features differ from adults in many ways. Intracranial hypertension with papilledema should obviously be treated promptly to avoid permanent visual damage, but various more or less invasive options have been proposed over the years, from bariatric surgery for obesity to optic nerve sheath fenestration. We report a prospective study on a group of 15 children, aged 3-16 years, with clinical and instrumental diagnosis of pseudotumor cerebri. All the patients were treated simply by external lumbar cerebrospinal fluid drainage with a mean volume of 10 ml/h for 3-5 days, with hypocaloric diet and with appropriate dosages of acetazolamide. All had immediate relief of headache, a considerable reduction in papilledema and marked improvement of both visual loss and cranial nerve palsies within 2 months. None of the patients relapsed during the follow-up period, ranging from 12-48 months.

Osteoblastomas are rare, benign bone tumors mainly arising from the long bones and the posterior vertebral arches. Skull localizations account for approximately 15% of cases. A total amount of thirty cases involving the temporal bone are reported in the literature. Clinical presentation of temporal osteoblastomas often includes local pain and swelling, while 7th and 8th cranial nerve impairment is rare. We report the novel finding of increase intracranial pressure syndrome secondary to dominant transverse-sigmoid sinus junction compression caused by a small temporal bone osteoblastoma. Excision of the tumor with the restoration of venous flow in the sigmoid sinus was followed by a prompt clinical improvement. In the management of patients with a venous sinus compression, restoration of venous drainage should be a priority.

Since children may not be able to complain of progressive reduction in optic acuity, visual assessment in infancy may present practical difficulties. The authors report a case of craniopharyngioma, which led a young child to early blindness before the correct diagnosis could be made. Similar to other reported cases, the authors found that surgery did not substantially modify the preoperative visual deficit. They conclude that minimal improvement in visual acuity can be expected despite successful microsurgical removal of the tumor.

Flexible endoscopy is a promising method to obtain complete pus removal even from loculated collections through a bur hole, avoiding large craniotomies and consequent potential complications.
