If a CPT is highly suspected in children, favorable treatment should be applied in timely fashion to prevent chronic hydrocephalus
. Compression of the brain tissue by chronic hydrocephalus
for a long period may affect the healthy development of the brain and the long-term prognosis of patients.
Pathological studies on the corpus callosum in acute and chronic hydrocephalus
patients suggest a potential causative role of neuronal degeneration during hydrocephalus [36, 37].
HCP occurs in about one fifth of patients in the early course (acute in the first 3 days or subacute in the 4-14 days) of SAH, while chronic hydrocephalus happens in 10%-20% of patients later in the course of SAH (after 2 weeks).

The patients without shunts had significantly higher AF than the control subjects, suggesting the persistence of chronic hydrocephalus even at the long-term follow-up (Figure 3).
The causes of chronic hydrocephalus in cryptococcal meningoencephalitis patients remain unclear; however, some clues in the changes of CSF dynamics may be helpful for finding answers.
Second, gaps still exist between the causal relationships of chronic hydrocephalus and cryptococcal meningoencephalitis pathogenesis.
In the third patient, the cyst caused chronic hydrocephalus
with intermittent symptoms of increased intracranial pressure.
Patients most commonly present with signs of intermittent, acute intracranial hypertension, but can present with chronic hydrocephalus
. Cysts that cause neurological signs and symptoms are usually greater than 1.5 cm in diameter (Greenberg).
