Craniopharyngiomas  (CP) are locally aggressive tumors with benign histology derived from embryonic remnants of the craniopharyngeal duct, with an incidence in Spain of 0.5-2 cases/million inhabitants/year, and an estimated prevalence of 1-3/100000 inhabitants.  Our hospital is a Reference Center in the treatment and follow-up of this disease for both children and adults.

Objective: To describe the main features of patients diagnosed with CP admitted in our center between years 2000 and 2012.

Material and Methods: Descriptive retrospective study. We performed a systematic search in our clinical database between years 2000 and 2012, including all patients with postoperative diagnosis of CP. Total sample: n=58.

Results: Our sample is composed by n=20 (54.2%) children, n=38 (45.8%) adults; n=30 males (51.7% of total sample, 62.5% children, 50% adults);  median of age at diagnosis 7 years ( children), 43 yr (adults). Main neurological manifestations at diagnosis were visual impairment (66.7% children, 75% adults) and headache (50% children, 70.6% adults), as well as intracranial hypertension (50% children, 33.3% adults);  the most frequent endocrine abnormalities were diabetes insipidus (50% children, 16.7% adults), menstrual disorders and growth impairment. The preferred surgical approach was an open technique. Postoperative sequelae were present in 97.9% of total patients (100% children, 96.7% adults), usually panhypopituitarism (92.3% children, 89.3% adults),  diabetes insipidus  (81.8% children, 76.9% adults) and obesity/polyphagia (71.4 % children, 40% adults), visual impairment (72.7% children, 63.6% adults), epilepsy (37.5% children, 25% adults), hydrocephalus (30% children, 30.8% adults), CSF leakage (45.5% children, 10.5% adults), and psychiatric disorders (80% children, 26.3% adults). In 47.7% of cases, external adjuvant treatment was applied, mainly radiotherapy (100% conventional radiotherapy in children, while in adults 67% was stereotactic vs. 33% conventional). The disease relapsed in 46.7% of total patients (69.2% children, 37.9% adults) requiring re-intervention approximately 2 years after initial surgery. Mortality rate is up to 20% (n=12).

Conclusions: Our results are consistent with currently available evidence about CP, as we observe high rates of morbidity and mortality. These findings support the need of a multidisciplinary approach to this disease in order to minimize the devastating consequences of both the disease and its treatment.
