Cavernous hemangioma in the masticatory space.

Hemangiomas are benign congenital vascular tumors that commonly arise in the head and neck regions. Although they present with indolent growth and involution in most cases, they can cause facial deformities. Hemangiomas have three subtypes: capillary, cavernous, and mixed.

Diagnosis of liver hemangioma using magnetic resonance diffusion-derived vessel density (DDVD) pixelwise map: a preliminary descriptive study.

Background: Liver hemangiomas (HGs) are characterized by cavernous venous spaces delineated by a lining of vascular endothelial cells and interspersed with connective tissue septa. Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

[Clinical management of patients with cavernous malformations of the central nervous system: an update and recommendations for clinical practice].

Cerebral cavernous malformations are benign vascular anomalies of the central nervous system (CNS). The clinical presentation of a cavernoma depends on its location. The majority of patients with cavernomas are asymptomatic.

Patient-reported outcomes in conservatively managed cerebral cavernous malformations.

Background: There is a paucity of studies on patient-reported outcomes and quality of life (QoL) in conservatively managed patients with a cerebral cavernous malformation (CCM).

Methods: This single-center observational study included consecutive adult CCM patients, diagnosed in 2000-2023, managed conservatively, and with at least 6 months of follow-up. Patients completed two validated patient-reported outcome measures (PROMs): EuroQol 5-dimensions 5-levels (EQ-5D-5L), and Patient-Reported Outcome Measurement Information System 29 (PROMIS-29).

Cavernous hemangioma of the rib mimicking malignant bone tumor: A case report.

Intraosseous hemangiomas are benign vascular tumors which are more commonly seen in the vertebrae and skull but they rare in the ribs. Rib hemangiomas can mimic malignant rib lesions and definitive clinical and imaging diagnosis might be difficult and pathological confirmation will be required. Here we report a rib hemangioma in a 49-year-old male presented with painless chest wall swelling of 9 years duration, on chest CT scan the lesion showed dense radiating type calcification with cortical destruction.

Pharmacological blocking of neutrophil extracellular traps attenuates immunothrombosis and neuroinflammation in cerebral cavernous malformation.

Cerebral cavernous malformation (CCM) is a neurovascular disease with symptoms such as strokes, hemorrhages and neurological deficits. With surgery being the only treatment strategy, understanding the molecular mechanisms of CCM is crucial in finding alternative therapeutic options for CCM. Neutrophil extracellular traps (NETs) were recently reported in CCM, and NETs were shown to have positive or negative effects in different disease contexts.

Radiologic Clue to Cavernous Sinus Hemangioma Diagnosis.

We describe a case of a 57-year-old woman presenting initially with diplopia who later developed retro-orbital and retroauricular pain. Examination showed right abducens nerve palsy and subsequent right trigeminal nerve hyperesthesia. Neuroimaging revealed a well-defined mass confined to the right cavernous sinus, with high T2 signal intensity and homogeneous enhancement on postgadolinium T1-weighted images.

Convexity dural hemangioma: illustrative case.

Background: Dural hemangiomas are a relatively rare form of intracranial mass, as hemangiomas tend to present in bone or as intraparenchymal lesions and only around 5%-13% have been reported to originate from the dura mater. Here, the authors present the case of a 46-year-old female who underwent craniotomy for a suspected convexity meningioma resection, which was unexpectedly found to be a dural capillary hemangioma.

Observations: The patient was a 46-year-old female who presented with a left frontal intracranial mass found incidentally and showed significant growth over 4 years.

Retinal arteriovenous malformation and cerebral cavernous malformation in a 6-year-old child.

Retinal arteriovenous malformations (AVMs) are rare congenital, nonhereditary vascular anomalies of the retina. We report the case of a 6-year-old child presenting with recurrent frontal headaches. Funduscopy examination revealed an AVM in the right eye, inferior to the optic nerve head.

[Cavernous hemangioma of the cauda equina: A case report].

Background: Cavernous hemangiomas are vascular malformations formed by groups of dilated sinusoids, organized in channels with a single layer of endothelium. Cavernous hemangiomas represent only 3% of all intradural lesions, and of these 5-12 % correspond to spinal cord lesions and those of the cauda equina are rare.

Clinic Case: A 57 years-old male patient is presented , without history of radiotherapy, who showed low back pain and contracture of the dorsal and paraspinal muscle during 6 months, evaluated in another hospital and diagnosed with a lumbar disc herniation, he was managed with analgesics and physiotherapy for two months, however the theraphy failed, the symptoms worsened and dysesthesias appeared in the gluteal and perianal region, with reduction of strength in both legs with predominance in the left leg, as well bladder sphincter dysfunction .

Case report: A second case of cerebral cavernous malformation after high-dose chemotherapy for medulloblastoma.

The development of cerebral cavernous malformations (CCMs) is a well-recognized sequela of irradiation to the brain in pediatric tumors, particularly in medulloblastoma, glioma, and acute lymphoblastic leukaemia. So far, only one case of cerebral cavernoma after chemotherapy with autologous hematopoietic stem cell transplantation (HSCT) has been described. We describe a case of a patient with medulloblastoma aged 18 months at the time of oncological diagnosis who was treated with high-dose chemotherapy followed by HSCT and who developed CCM two years later.
