Background and aims: Cerebellar pilocytic astrocytoma is
the most common type of benign tumor located in the
cerebellum in children, and postoperative after-effects can
prevent recovery treatment, these children frequently need
care assistance.
Methods: Prospective study of late postoperative
neurological manifestations (≥ 2 years after intervention) in
14 children (aged 7–18 years) operated on with cerebellar
pilocytic astrocytoma between 2012–2018, who were not
subjected to radiotherapy or chemotherapy.
Results: The most affected age: 10–14 years (42.9%),
followed by 7–9 years (37.7%), then 14–18 years (21.4%).
Location in the cerebellum: vermis – 10 children, vermis
and both hemispheres – 1, right cerebellar hemisphere – 1,
left cerebellar hemisphere – two children. Postoperative
syndromes: posterior fossa – eight children (57.1% [II
60.33–44.17], p=0.05); moderate and severe motor deficit
– 10 (71.4%, [II 83.47–59.33], p=0.07), mild – one child;
expressive language deficit – five (35.7% [II 50.31–24.69],
p=0.05), spontaneous conversation – three (21.4%, [II
32.37–10.43], p=0.06). At the localization in the vermis
persisted the deficit of emotional control (anxiety, panic
attacks, aggression), as well as eating disorders – five
(35.7%); emotional lability – 12 (85.7%); cognitive
disorders – 12 (85.7%); vegetative disorders (bradycardia,
orthostatic syncope, hypotension, hyperhidrosis, flatulence,
asthenia, insomnia) – 12 (85.7%) children; and in the left
cerebellar hemisphere – dysmetry and dysdiadokokinesis.
Conclusion: In children operated on with cerebellar
astrocytoma in the postoperative period, neurological
manifestations with moderate and severe motor deficit
persist, as well as the symptoms of the vegetative nervous
system, negatively influencing their recovery.
Disclosure: Estimation of neurological manifestations in
the postoperative period in children operated on with
cerebellar pilocytic astrocytoma who have not undergone
radiotherapy or chemotherapy.
