Abstract
BACKGROUND Giant cavernous malformations (GCMs) are rare and poorly characterized neurovascular lesions in adults or children and often misclassified. In this study, we provide a review of pediatric GCM cases to highlight this rare entity as an important differential diagnosis in preoperative assessment. METHODS We report a pediatric case of GCM that presented as an intracerebral, periventricular, and infiltrative mass lesion. We performed a systematic review of published literature describing cases of GCM in children using the PubMed, Embase, and Cochrane Library databases. Studies describing cerebral or spinal cavernous malformation >4 cm were included. Demographic, clinical, radiographic, and outcome data were extracted. RESULTS Thirty-eight studies accounting for 61 patients were reviewed. most patients were 1-10 years old and 55.73% were male. Average lesion sizes ranged between 4 and 6 cm (40.98% >6 cm; 8.19% >10 cm). Supratentorial localization was most common (75.40%), with frontal and parieto-occipital regions being frequent localizations. Infratentorial lesions (24.60%) were located within the cerebellum (16.39%) and brainstem (8.19%). One case of spinal cavernoma was found. The main clinical manifestations were seizures (44.26%), focal neurologic deficit (36.06%), and headache (22.95%). Imaging showed contrast enhancement (36.06%), cystic features (27.86%), and infiltrative growth pattern (4.91%). CONCLUSIONS GCMs show variable clinical and radiologic features, representing a diagnostic challenge for treating surgeons. Imaging may show various tumorlike features such as cystic or infiltrative patterns with contrast enhancement. The existence of GCM should be considered preoperatively. Gross total resection should be attempted whenever possible, because it correlates with a good recovery and long-term outcomes. Also, a clear definition criteria of when a cerebral cavernous malformation is termed giant should be established.

Abstract
INTRODUCTION Intracranial cavernous malformations (CMs) are rare vascular malformations of the central nervous system in children. Infantile patients, being a developmentally vulnerable age group, pose a special challenge for management of these lesions. We pooled data from infantile patients diagnosed at our institution and individual cases published in the literature to provide input towards therapeutic decision-making. METHODS A systematic search of PubMed, MEDLINE, Embase, and Scopus was performed in accordance with PRISMA guidelines to identify all reported cases of intracranial CMs in the literature for infantile patients aged ≤ 2 years. In addition, cases from our institution diagnosed between 2010 and 2020 were also included. Individual cases were pooled and analyzed for clinical presentation, natural history, and outcomes from conservative and surgical management. RESULTS A total of 36 cases were included, of which 32 were identified from the literature. Median age at presentation was 14 months (range: 2 days to 24 months) months; 53% (n = 19) were females. Most cavernomas (64%, 23/36) were supratentorial, while 30% (n = 11) were located in brainstem and 5.5% (n = 2) in the cerebellum. With the exception of one patient, all cases were reported to be symptomatic; seizures (n = 15/31, 48.3%) and motor deficits (n = 13/31, 42%) were the most common symptom modalities. A total of 13 patients were managed conservatively upon initial presentation. No symptomatic hemorrhages were observed during 26 total person-years of follow-up. A total of 77% (28/36) underwent surgery; either upfront (23/28, 82%) at initial presentation or following conservative management. Among 12 patients who had preoperative seizures, 11/12 (91.6%) achieved seizure freedom post-resection. Among 7 patients who presented with hemiparesis preoperatively, 5 (71%) demonstrated some improvement, while 1 remained unchanged, and another patient with a brainstem cavernous malformation had worsening of motor function postoperatively. Postoperative recurrence was noted in 3 cases (3/27, 11%). CONCLUSION Annual risk of repeat hemorrhage may be low for infantile patients with intracranial cavernous malformations; however, better follow-up rates and higher number of cases are needed to make a definitive assertion. Surgical resection may be associated with high rates of epilepsy cure and provide improvement in neurological function in a select number of cases.

Abstract
Association of developmental venous anomaly (DVA) and cavernous malformation (CM) of the posterior fossa is rare. If bleeding occurs, it must be assigned to the CM. Developmental venous anomalies, considered as normal vascular variation, are rarely symptomatic. Indeed, the CMs are true malformations and have a high bleeding potential.

Abstract
INTRODUCTION Cavernous angiomas of the brain (CCM) are being increasingly diagnosed, especially in the paediatric age group. Though classic presentations with haemorrhage or seizures are well recognised, presentation as a large lesion with mass effect is rare and creates difficulty in diagnosis as well as management. METHODS Our cases of paediatric giant CCMs that presented as a 'mass lesion' are reported here, and the PubMed database for giant CCMs in the paediatric population is reviewed. All articles where the size of the lesion was reported to be > 4 cm were selected for analysis to study the varying modes of presentation, treatment, and outcome; to gain a proper perspective on this distinct entity of 'giant CCMs'. RESULTS Analysis of a total of 53 cases (inclusive of our 3 cases) reported so far showed slight male preponderance (58.49%). The largest reported lesion was 14 cm in largest diameter. Most of the lesions (83.02%) occurred in the supratentorial region. In the infratentorial region, paediatric giant CCMs were more commonly seen in the cerebellum than in the brainstem. Seizures were observed in 47.17% at presentation. Features of mass effect were the mode of presentation in all our cases, and literature analysis has shown raised intracranial pressure in 37.74% (20 patients) and focal neurological deficit in 33.96% (18 patients) at presentation. Macrocephaly was seen in younger children up to the age of 7 years (16.98% or 9 patients). Gross total resection was carried out (with a good outcome) in all our cases and in 36 of the other 49 analysed patients who were operated on. DISCUSSION About one-fourth of CCMs occur in paediatric patients. Giant CCMs are rare but can present in children even in the immediate post-natal period. Features of a mass lesion such as raised intracranial pressure, macrocephaly, and focal neurological deficit are much more common than their smaller counterparts. Their appearance on imaging also often causes diagnostic dilemmas with other intracranial mass lesions. Timely surgery with standard microsurgical principles leads to a favourable outcome in the majority. CONCLUSION Giant CCMs, though rare, often present as a diagnostic challenge. Presentation with mass effect is common, and complete microsurgical excision remains the mainstay of treatment. Though transient neurological deficits may be encountered with this strategy, the long-term outcome remains favourable.

Abstract
INTRODUCTION Giant cavernomas (GCMs) are angiographically occult vascular malformations of the central nervous system measuring at least 4 cm in diameter. These are rare lesions, especially in the cerebellum. As such, the clinical and radiologic features, surgical management, and outcomes of treatment for this condition are unknown. METHODS We performed a systematic review of SCOPUS and PubMed databases for case reports and case series of histopathologically proven GCMs arising from the cerebellum in the pediatric population, and included a case managed at our center. Data on clinical presentation, imaging features, surgical treatment and outcomes of management were collected. RESULTS A total of 10 cases were identified from the systematic review, including our case report. The patients' median age was 6 months, with a slight male sex predilection (1.5:1). The most common neurologic manifestations were bulging fontanelle in infants, and headache and focal cerebellar deficits in older children. Surgical excision was done in all cases, while 50% of the cases had CSF diversion surgery done prior to excision. In cases with reported outcome, complete neurologic recovery was achieved in seven while partial recovery was reported in one case. No deaths were reported at median follow-up of 12 months. CONCLUSION Our case report and systematic review show that giant cerebellar cavernoma is a rare differential diagnosis for symptomatic hemorrhagic cerebellar masses in the pediatric age group. Mainstay of treatment is surgical excision, which can be associated with favorable outcome in most cases.

Abstract
Cavernous malformations (CM) are angiographically occult vascular malformations. CM appear as discrete, small lesions with mixed-signal characteristics on T2 reflecting the underlying pathology. However, the appearance is not pathognomonic. Distinguishing true CM from hemorrhagic tumors can be difficult. We report 5 cases of tumors mimicking CMs. We compared clinical, initial radiologic features, and MRI evolution between 5 tumor mimics and 51 true hemorrhagic, sporadic, brain CM. Compared to true CM, mimic patients were older (47.0 vs. 38.3 years; p = 0.076) and more likely to have a history of primary neoplasm (60% vs 12%; p = 0.0267). Radiologically, the CM mimics demonstrated a higher likelihood of lesion enhancement on the initial diagnostic MRI (60% vs. 16.7%%; p = 0.0609). On follow-up MRI (<1 year after baseline), CM mimics typically had persistent edema (100.0% vs. 6.25%, p = 0.0003) and demonstrated mixed density on ADC (100% vs. 32.1%; p = 0.0199) as well as increased likelihood of enhancement (100% vs 25.8, p = 0.0852). CM mimics were less likely to evolve to Type 2 or 3 lesions (25.0% vs. 84.4%, p = 0.0278). Clinical and radiologic factors may distinguish tumor metastases from true hemorrhagic CM. CM mimics should be suspected in older patients with a history of neoplasm and contrast enhancement on initial MRI. A repeat MRI within 90 days post-initial hemorrhage should be considered to confirm CM diagnosis. Persistent edema without rebleed, lesion enhancement, mixed signal on apparent diffusion co-efficient, and persistence of a Type 1 lesion should raise suspicion of a metastatic tumor.

Abstract
Intracranial giant cavernous malformations (GCMs) are rarely reported because of their extremely low incidence. Knowledge of GCM is poor. The goals of this study were to analyze the epidemiological characteristics, clinical manifestations, radiological findings, microsurgical treatment, and neurological outcomes of GCMs. From January of 2003 to December 2016, nine GCM patients who underwent neurosurgical treatment at Beijing Tiantan Hospital were chosen for analysis and their records were reviewed. We also performed an exhaustive literature search and identified all previously reported GCMs. The study population consisted of three males and six females (mean age, 25.1 years). The mean diameter of the malformations was 6.7 cm (range, 6.0-8.4 cm). The most common clinical manifestations were the symptoms caused by mass effect. Radiologically, all GCMs showed mixed T1 and T2 signals; five of them exhibited minimal enhancement after contrast administration. Gross total resection was achieved in all patients without surgical mortality. Postoperatively, three patients developed new surgical complications, including left limbs weakness and left side paralysis. The mean follow-up period after diagnosis was 69.3 months (range, 16-149 months); five patients (55.6%) had achieved full recovery and the remaining four cases (44.4%) were improved to some extent. GCM is a rare subgroup of vascular malformations; it is more prone to occur in children and adolescents. Microsurgical resection should be the treatment of choice for GCMs, and despite their giant size, excellent surgical outcomes after total removal could be achieved.

Abstract
BACKGROUND AND IMPORTANCE Giant cavernous malformations (GCM) are low flow, angiographically occult vascular lesions, with a diameter >4 cm. Cerebellar GCMs are extremely rare, with only seven cases reported based on English literature. These lesions are most commonly seen in the pediatric age group, which is known to have an increased risk of hemorrhage, being surgery clearly recommended. CLINICAL PRESENTATION An 18-month-old girl presented with a 6-month history of cervical torticollis and upper extremities clumsiness. An MRI revealed a 57 × 46 × 42 mm multi-cystic, left cerebellar hemisphere mass, showing areas of hemorrhages and cysts with various stages of thrombus. There was no enhancement with contrast. Cerebral angiography ruled out an arteriovenous malformation. She underwent a left paramedian occipital craniotomy, and macroscopic gross total resection was accomplished. Histopathologic examination was consistent with a cavernous malformation. After surgery, the patient had no new neurological deficit and an uneventful postoperative recovery. Follow-up MRI confirmed total removal of the lesion. CONCLUSION Cerebellar GCMs in children are symptomatic lesions, which prompt immediate surgical treatment. These are rare lesions, which can radiologically and clinically mimic a tumor with bleed, having to be considered in the differential diagnosis of neoplastic lesions. Cerebellar GCMs might be suspected in the presence of large hemorrhagic intra-axial mass with "bubbles of blood," multi-cystic appearance, surrounded by hemosiderin ring, fluid-fluid levels, and accompanying edema-mass effect. Careful radiological study provides a preoperative diagnosis, but its confirmation requires histopathological examination. Complete surgical removal should be attempted when possible.

Abstract
Pilocytic astrocytoma (PA) commonly occurs during the first two decades of life. Typical locations include cerebellum, optic nerve, optic chiasm/hypothalamus and brainstem. PA should be considered in the differential diagnosis of patients with brain tumors manifesting with hemorrhagic onset. We report a case of a hemorrhagic onset of cerebellar PA in a young adult with imaging findings mimicking cavernous angioma. We also discuss imaging features and histological characteristics with a focus on the etiology of the hemorrhagic onset.
