Abstract
This study investigates structural alterations of the corpus callosum in children diagnosed with infantile hydrocephalus. We aim to assess both macrostructural (volume) and microstructural (diffusion tensor imaging metrics) facets of the corpus callosum, providing insights into the nature and extent of alterations associated with this condition. Eighteen patients with infantile hydrocephalus (mean age = 9 years) and 18 age- and sex-matched typically developing healthy children participated in the study. Structural magnetic resonance imaging and diffusion tensor imaging were used to assess corpus callosum volume and microstructure, respectively. Our findings reveal significant alterations in corpus callosum volume, particularly in the posterior area, as well as distinct microstructural disparities, notably pronounced in these same segments. These results highlight the intricate interplay between macrostructural and microstructural aspects in understanding the impact of infantile hydrocephalus. Examining these structural alterations provides an understanding into the mechanisms underlying the effects of infantile hydrocephalus on corpus callosum integrity, given its pivotal role in interhemispheric communication. This knowledge offers a more nuanced perspective on neurologic disorders and underscores the significance of investigating the corpus callosum's health in such contexts.

Abstract
Corpus callosum swelling has been reported to occur after ventriculoperitoneal shunting for long-standing hydrocephalus. This report presents a case of corpus callosum swelling after intraventricular tumor resection. A 34-year-old woman presented with a headache that worsened over 1 month. Magnetic resonance (MR) images revealed a mass lesion in the left lateral ventricle and obstructive hydrocephalus. She underwent subtotal resection with a transcallosal approach. After tumor resection, she had long-lasting status epilepticus followed by consciousness disturbance. T2-weighted MR images obtained 8 hr after the operation showed a hyperintense area in the corpus callosum. The patient then presented with bilateral dilated pupils 14 hr after the operation due to acute hydrocephalus and tension pneumocephalus. An emergent re-craniotomy was performed and a ventricular drain was placed. The patient recovered consciousness 3 days after the operation. However, she experienced progressive corpus callosum swelling 25 days after the operation, which improved since then. Approximately 4 months after the operation, she returned to her usual workplace with no neurocognitive functional decline. Two years later, she was doing well with no radiological abnormal findings except corpus callosum thinning. Thus, corpus callosum swelling can develop not only after shunting for chronic hydrocephalus but also after intraventricular tumor resection. It occurred relatively acutely and there was no decline in intelligence after long-term follow-up. This case suggests that corpus callosum swelling after intraventricular tumor resection is a rare but noteworthy complication that can improve without intervention.

Abstract
We report 3 cases of Global rostral midbrain syndrome (GRMS) and Corpus Callosum (CC) infarction, in the context of hydrocephalus followed by shunt dysfunction and slit ventricles. Prior shunt implantation had been indicated for adult-onset hydrocephalus secondary to aqueductal stenosis of varying causes. All three patients had been stable for months before developing repeated shunt dysfunctions, ultimately progressing to parkinsonism, Parinaud syndrome, akinetic mutism, pyramidal signs, cognitive impairment, CC infarction and slit ventricles, in the context of CSF overdrainage. Parkinsonism-related symptoms responded to dopa in all cases, but Parinaud syndrome and cognitive impairment persisted. Although GRMS has been described in the context of a transtentorial pressure gradient after shunt blockage, in these three cases with similar clinical presentation, reverse transtentorial pressure gradient and slit ventricles due to shunt overdrainage was the likely cause. The authors discuss the role of CC infarction and provide a detailed analysis after gathering previously described data, to unify information under a recognizable clinical entity and better understand the underlying pathophysiology, treatment options and outcome.

Abstract
MRI signal changes in the corpus callosum can be seen in 8.3% of patients following shunt insertion for obstructive hydrocephalus. Several causes have been hypothesised, including mechanical compression, decompression associated oedema and ischaemia, and overshunting. We present a case of a patient with a pineal tumour of intermediate differentiation (WHO grade III), which had caused long-term obstructive hydrocephalus due to compression of the tectal plate and cerebral aqueduct. Following insertion of a shunt, prominent changes in the corpus callosum became evident on CT and MRI characterised by oedema and swelling, particularly affecting the dorsal surface of the corpus callosum. This pattern of signal change, although dramatic, should not be mistaken for other pathologies.

Abstract
BACKGROUND Corpus callosum (CC) infarction has been reported to be rare because of the rich blood supply in the CC. The pathophysiology of CC infarction associated with acute hydrocephalus is unknown. The aim of the present study was to clarify the characteristics and mechanism of CC infarction associated with acute noncommunicating hydrocephalus (ANCH). METHODS We reviewed clinical the data from all patients who had undergone surgical intervention for ANCH at Chiba University Hospital from January 2008 to March 2018. Patients with vascular lesions, a history of hydrocephalus, and lacking magnetic resonance imaging studies were excluded. The clinical, surgical, and radiological parameters were obtained retrospectively for pathophysiological analysis. RESULTS A total of 23 patients with ANCH who had undergone surgical intervention and had met the inclusion criteria were included in the present study. Of the 23 patients, 6 (23%) had developed CC infarction. All CC infarctions were located in the splenium. Although no clinical or surgical features were associated with splenial infarction, the radiological parameters of lateral ventricle enlargement and a narrower callosal angle at the posterior commissure and the foramen of Monro were significantly associated with splenial infarction. CONCLUSION The present study has presented evidence that increased intraventricular pressure by ANCH applied transversely in the splenium will directly induce compression of the superior branch of the posterior callosal artery and pericallosal pial plexus, resulting in splenium-specific infarction in patients with ANCH.

Abstract
Idiopathic normal pressure hydrocephalus (INPH) is characterized by the clinical triad of gait and cognitive dysfunction and urinary incontinence. Ventriculoperitoneal (VP) shunting is often required for treatment. Review of literature shows few case reports discussing benign magnetic resonance imaging (MRI) T2 hyperintense changes in the corpus callosum of NPH patients after shunting due to mechanical compression of the middle and posterior regions of the body against falx cerebri leading to ischemic demyelination. These changes can be a delayed phenomenon and may interfere with clinical evaluation and may lead to unnecessary procedures and investigations. We present a patient with NPH who was admitted to the neurocritical care unit in coma with quetiapine and trazodone overdose. Diffuse changes in the body of the corpus callosum were seen on MRI suspicious for acute vasogenic edema due to drug overdose. However, it was later determined to be due to the VP shunting for the NPH. We report this case to raise the awareness of neuroimaging changes in patients with NPH who have VP shunting.

Abstract
Alterations in the appearance of the corpus callosum occasionally occur following successful ventricular decompression in patients with chronic hydrocephalus. There are certain features on imaging that suggest the diagnosis of what the authors propose be termed "postshunting corpus callosum swelling," including diffuse high T2 signal predominantly affecting the body of the corpus callosum, with transverse orientation along the crossing white matter tracts and scalloping along the posterior margin of the structure. In this report, the authors demonstrate preservation of the corpus callosum white matter fiber tracts by using diffusion tensor imaging with tractography.

Abstract
BACKGROUND Normal pressure hydrocephalus (NPH) is associated with corpus callosum abnormalities. OBJECTIVES To study the clinical and neuropsychological effect of callosal thinning in 18 patients with idiopathic NPH and to investigate the postsurgical callosal changes in 14 patients. METHODS Global corpus callosum size and seven callosal subdivisions were measured. Neuropsychological assessment included an extensive battery assessing memory, psychomotor speed, visuospatial and frontal lobe functioning. RESULTS After surgery, patients showed improvements in memory, visuospatial and frontal lobe functions, and psychomotor speed. Two frontal corpus callosum areas, the genu and the rostral body, were the regions most related to the clinical and neuropsychological dysfunction. After surgery, total corpus callosum and four of the seven subdivisions presented a significant increase in size, which was related to poorer neuropsychological and clinical outcome. CONCLUSION The postsurgical corpus callosum increase might be the result of decompression, re-expansion and increase of interstitial fluid, although it may also be caused by differences in shape due to cerebral reorganisation.

Abstract
OBJECTIVES Our aim was to evaluate corpus callosum functioning in a group of patients with normal pressure hydrocephalus (NPH) before and after shunting. METHODS Left ear-extinction under a dichotic listening task was evaluated in twenty-three patients with NPH, 30 patients with Alzheimer's disease and 30 aged controls. RESULTS Patients with NPH had higher levels of left ear extinction than the control and Alzheimer's groups. Sixty-one percent of NPH patients exhibited left ear suppression, compared with 13% of Alzheimer's patients and 17% of controls. Following surgery, NPH patients showed a significant change in the degree of asymmetry in the dichotic listening task. CONCLUSIONS Hydrocephalus was associated with left-ear extinction,which diminished after surgery. Our results may indicate reversible functional damage in the corpus callosum.

Abstract
Diffuse callosal signal changes can rarely occur following successful shunting for obstructive hydrocephalus. We report on a patient who underwent ventriculoperitoneal shunting for aqueductal stenosis and required two revisions for neurological deterioration and presumed shunt malfunction. Extensive changes involving the corpus callosum, periventricular white matter and optic chiasm were noted after the first, and were prominent after second shunt revision. Thus, post-shunting callosal changes may be associated with more extensive white matter disease, and may not imply wide pressure fluctuations. However, they need not prompt further intervention.
