BACKGROUND AND OBJECTIVE: Liver tumor segmentation (LiTS) accuracy on contrast-enhanced computed tomography (CECT) images is higher than that on non-contrast computed tomography (NCCT) images. However, CECT requires contrast medium and repeated scans to obtain multiphase enhanced CT images, which is time-consuming and cost-increasing. Therefore, despite the lower accuracy of LiTS on NCCT images, which still plays an irreplaceable role in some clinical settings, such as guided brachytherapy, ablation, or evaluation of patients with renal function damage...

OBJECTIVES: The aim of this study is to evaluate the diagnostic accuracy of dual-energy computed tomography (DECT)-based Rho/Z maps in differentiating between metastases and benign liver lesions in patients diagnosed with malignant melanoma compared to conventional CT value measurements. METHODS: This retrospective study included 73 patients (mean age, 70 ± 13 years; 43 m/30 w) suffering from malignant melanoma who had undergone third-generation DECT as part of tumor staging between December 2017 and December 2021...

Capillary hemangiomas, usually found in skin and mucosal tissues, are rarely encountered within the spinal cord, presenting a significant diagnostic challenge. We report a rare case of intradural extramedullary capillary hemangioma at the conus medullaris in a 66-year-old female patient. Our initial diagnosis leaned towards a cystic hemangioblastoma based on MRI findings due to the presence of cystic formation with an enhanced mural nodule. However, surgical exploration and subsequent pathological examination revealed the lesion as a capillary hemangioma...

An epithelioid hemangioma (EH) is a rare benign vascular lesion that is usually seen in superficial small vessels within the dermis and subcutaneous tissue. Intravascular epithelioid hemangiomas of large and medium-sized vessels are rare, and only a handful of cases have been reported in the literature. Intravascular epithelioid hemangiomas are biologically benign and best treated by complete surgical excision. On occasion, lesions have been associated with aneurysmal changes in the affected vessel. Local recurrence may occur, and close clinical follow-up is advised...

BACKGROUND: Infantile hemangiomas (IHs) are common benign vascular tumors in infants. Apelin, an endogenous cytokine, is implicated in the angiogenesis of neoplastic diseases. We aimed to explore the association between apelin and IHs, providing a foundation for clinical applications. METHODS: We identified differential expression of apelin in proliferative IHs compared to healthy controls (HCs) through bioinformatics analysis of publicly available databases and verified by Immunofluorescence...

Cavernous hemangioma, currently known as "cavernous venous malformation," is a common, benign, non-infiltrative, slowly progressive vascular malformation of the orbit presenting in adults. We report the case of a 9-year-old girl who presented with a painless palpable mass over the right upper eyelid of 7 years' duration. A computed tomography scan of the orbits revealed a heterogeneously enhancing, well-circumscribed mass in the right upper eyelid with no orbital extension. A transcutaneous excisional biopsy with histopathology disclosed cavernous venous malformation...

AIM: To describe the rates of stroke and craniocervical vasculopathy progression in children with posterior fossa malformations, hemangioma, arterial anomalies, coarctation of the aorta/cardiac defects, and eye abnormalities (PHACE) syndrome. METHOD: A single-center, retrospective natural history study of children with PHACE syndrome. Clinical and sequential neuroimaging data were reviewed to study the characteristics and progression of vasculopathy and calculate the rates of arterial ischemic stroke (AIS) and transient ischemic stroke (TIA)...

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6...

The present aimed to examine the effectiveness of polidocanol-based foam sclerotherapy for oral venous malformations (OVMs). The present study performed a retrospective analysis of patients with OVMs who underwent sclerotherapy using polidocanol. Patients achieving the complete resolution of OVM were categorized as having a complete response (CR), those with a reduction in size from the initial diagnosis were categorized as having a partial response (PR), those with no change in size as stable disease (SD), and those with an increase in size as progressive disease (PD)...

(1) Background: this case series and literature review aims to evaluate the efficacy and safety of electrochemotherapy in the management of aggressive spinal hemangiomas, presenting two distinct cases. (2) Methods: we present two cases of spinal aggressive hemangioma which were refractory to conventional treatments and underwent electrochemotherapy. Case 1 involves a 50-year-old female who presented with an aggressive spinal hemangioma of L1, who previously underwent various treatments including surgery, radio-chemotherapy, and arterial embolization...

BACKGROUND: Beckwith-Wiedemann syndrome (BWS) is an overgrowth disorder that exhibits etiologic genomic imprinting characterized by molecular heterogeneity and phenotypic variability. Associations with localized developmental dysplastic chondromatous lesions and cortical neuronal heterotopias have not previously been described. CASE PRESENTATION: A 33-week gestational age female had an omphalocele and intractable hypoglycemia at birth. The placenta demonstrated placental mesenchymal dysplasia...

BACKGROUND: Colorectal cavernous hemangioma is a rare vascular malformation resulting in recurrent lower gastrointestinal hemorrhage, and can be misinterpreted as colitis. Surgical resection is currently the mainstay of treatment, with an emphasis on sphincter preservation. CASE SUMMARY: We present details of two young patients with a history of persistent hematochezia diagnosed with colorectal cavernous hemangioma by endoscopic ultrasound (EUS). Cavernous hemangioma was relieved by several EUS-guided lauromacrogol injections and the patients achieved favorable clinical prognosis...

INTRODUCTION AND IMPORTANCE: PHACE syndrome is a rare neurocutaneous disorder characterized by large segmental hemangiomas on the face and is associated with multiple developmental defects. PHACE stands for posterior fossa malformations, hemangiomas, arterial abnormalities, cardiac defects, and eye anomalies, with the most common manifestation being hemangioma in the cervico-facial region in early childhood. CASE PRESENTATION: The authors report a case of a 15-year-female with complaints of facial hemangioma which on multisystemic imaging showed features of central nervous system (CNS) anomalies that led to the diagnosis of PHACE syndrome...

Birthmarks in newborns can be classified as vascular, melanocytic or pigmented, or markers of underlying developmental abnormalities of the nervous system. A nevus simplex is a benign capillary malformation. Newborns with a nevus flammeus can be safely treated before one year of age with a pulsed dye laser to reduce the visibility of lesions. Infantile hemangiomas should be treated with systemic beta blockers if there is a risk of life-threatening complications, functional impairment, ulceration, underlying abnormalities, permanent scarring, or alteration of anatomic landmarks...

Vascular anomalies represent a diverse group of disorders of abnormal vascular development or proliferation. Vascular anomalies are classified as vascular tumors and vascular malformations. Significant advances have been made in the understanding of the pathogenesis, natural history, and genetics of vascular anomalies, allowing for improvements in management including targeted molecular therapies. Infantile hemangiomas are the most common vascular tumor of childhood and follow a distinct natural history of proliferation and involution...

An outborn male term neonate presented with a complaint of respiratory distress since birth on day 9 of life. On examination, baby was having tachypnoea, tachycardia and hepatomegaly. The baby was delivered at term gestation and cried immediately after birth. The chest X-ray showed cardiomegaly. The abdomen ultrasound showed a complex cystic vascular lesion suggestive of hepatic haemangioma. The echocardiography showed an atrial septal defect. The baby was initially treated conservatively along with specific treatment (steroids and propranolol) for haemangioma for 6 weeks...

BACKGROUND: Intradural, extramedullary capillary hemangiomas of the cauda equina are exceedingly rare malformations arising from the endothelial cells of the nervous system vasculature. Roughly 20 cases have been reported in the literature, with the youngest and only pediatric case being in a 17-year-old patient. We report the youngest case of intradural extramedullary capillary hemangioma of the cauda equina in a 14-year-old patient. CASE DESCRIPTION: A 14-year-old female presented with two-month history of low back pain with bilateral leg pain and numbness...
