Primary intraosseous vascular malformations (PIVMs) are rare intraosseous lesions, accounting for approximately 0.5–1% of all intraosseous tumours. In this case report, we aimed to present a rare case of intraosseous vascular malformation causing a large lytic area in the parietal bone. A 25-year-old male patient was admitted to the clinic with a mass on the parietal bone. On physical examination, it was observed that the hair density on the mass was decreased, the mass had a soft consistency, and there was no pain on palpation. The patient was operated under local anaesthesia with a provisional diagnosis of a trichilemmal cyst. However, intraoperative diagnosis was a vascular malformation. There was a 3-cm full-thickness defect on the parietal bone caused by the lesion. The mass was excised completely while preserving the integrity of the dura. The resulting defect was reconstructed with bilateral rotation advancement flaps. The calvarial defect was not reconstructed due to equipment inadequacy. No complications were encountered in the postoperative period. Ninety-three PIVM cases have been reported in the skull since 1845. In very few of these cases, the mass is located in the parietal bone. The pathogenesis of PIVMs is not completely understood. The definitive diagnosis is made by histopathological examination. The therapeutic gold standard is surgery. Surgeons should keep in mind that radiological examination before the operation could prevent undesirable complications.

Lymphatic-venous malformations (LVMs) are development defects that result in abnormal connections between the lymphatic and venous systems. The authors describe a 7-weeks-old female infant who presented with a right orbital LVM extending to the ipsilateral cheek and subconjunctiva of the right eye, intracranial developmental venous anomalies in the right cerebellum, and a significant right eye intraocular retinal vascular malformation. Since orbital LVM is usually diagnosed in infancy or childhood, pediatric ophthalmologists should actively look for intraocular vascular malformations as such findings can poorly affect a patient’s vision.

Venous malformation (VM) is a congenital vascular malformation (CVM) that develops along the venous system through the various stages of embryogenesis. Older terminology and classification were often misleading and confusing. A newer classification system has emerged that is based on advances in the study of these conditions and is useful in contemporary management. The Hamburg classification was introduced after reappraisal of older terminology and has become the standard system for contemporary classification, which is based on anatomical, pathological and embryological criteria.

Venous malformation (VM) is the most common congenital vascular malformation (CVM), which usually presents as a single lesion in the majority of cases. It also presents as a mixed lesion combined with other CVMs (e.g. lymphatic malformation and arteriovenous malformation [AVM]). Therefore, the diagnosis of VM should include an appropriate work-up, to not only confirm and characterize the VM as either extratruncular or truncular but also to diagnose or exclude the presence of other CVMs. The diagnosis of VM can be made safely using non-invasive to minimally invasive studies, which can also distinguish VM from infantile haemangioma. Invasive studies, such as venography and arteriography, are generally reserved for therapeutic planning and diagnosis of more virulent CVMs (e.g. AVM). The work-up of VM should include a complete assessment of the extent and severity of the primary VM lesion. In addition, its embryologic origin, as well as its haemodynamic characteristics and secondary effects should also be determined.

✓ The cases of seven patients with intramedullary, cryptic vascular malformations of the spinal cord are reported. In all patients, the clinical course was progressive; a Brown-Séquard syndrome was the most common presenting symptom complex. Magnetic resonance (MR) imaging was performed in all patients. The pattern seen most often was a focus of high signal (on both T1- and T2-weighted MR images) surrounded by a larger zone of low signal (best seen on T2-weighted images), and was remarkably similar for all patients. Six patients underwent surgical exploration; removal of the lesions halted the progression of symptoms in five patients, and one patient had worsened sensory function after surgery. Motor function did not decrease postoperatively in any patient. The one patient who refused surgery has continued to decline neurologically. Histopathological examination of surgical specimens showed a cavernous malformation in one patient, a venous malformation in one, venous varices in two, and organizing hematomas in two; these findings are markedly different from those in previously reported cases of cryptic vascular malformations.

Congenital lipomatous overgrowth, vascular malformations, and epidermal nevi (CLOVE) syndrome is a recently delineated disorder that comprises vascular malformations (typically truncal), dysregulated adipose tissue, scoliosis, enlarged bony structures (typically of the legs) without progression, or distorting bony overgrowth. The name CLOVE was subsequently extended to CLOVES to emphasize the association with scoliosis/skeletal and spinal anomalies and seizures/central nervous system malformations. We herein report a very rare case of CLOVES syndrome with the findings of lipomatous overgrowth in the cheek (facial asymmetry), vascular malformation (hemangiomas), epidermal nevi (large port wine stains), and skeletal abnormalities (widened first interdigital space, dystrophia in the nail of the first digit of the right foot, and bilateral hypertrophy of the first digits of the feet).

Abstract Introduction CNS cavernomas are a type of raspberry-shaped vascular malformations that are typically asymptomatic, but can result in haemorrhage, neurological injury, and seizures. Here, we present a rare case of a brainstem cavernoma that was surgically resected whereafter an upbeat nystagmus presented postoperatively. Case report A 42-year old man presented with sudden-onset nausea, vomiting, vertigo, blurred vision, marked imbalance and difficulty swallowing. Neurological evaluation showed bilateral ataxia, generalized hyperreflexia with left-sided predominance, predominantly horizontal gaze evoked nystagmus on right and left gaze, slight left labial asymmetry, uvula deviation to the right, and tongue deviation to the left. MRI demonstrated a 13-mm cavernoma with haemorrhage and oedema in the medulla oblongata. Surgery was performed via a minimal-invasive, midline approach. Complete excision was confirmed on postoperative MRI. The patient recovered well and became almost neurologically intact. However, he complained of mainly vertical oscillopsia. The videonystagmography revealed a new-onset spontaneous upbeat nystagmus in all gaze directions, not suppressed by fixation. An injury of the rarely described intercalatus nucleus/nucleus of Roller is thought to be the cause. Conclusion Upbeat nystagmus can be related to several lesions of the brainstem, including the medial longitudinal fasciculus, the pons, and the dorsal medulla. To our knowledge, this is the first case of an iatrogenic lesion of the nucleus intercalatus/nucleus of Roller resulting in an upbeat vertical nystagmus. For neurologists, it is important to be aware of the function of this nucleus for assessment of clinical manifestations due to lesions within this region.

We present a rare case of KRAS keratinocytic epidermal nevus syndrome with lymphatic malformation, responsive to treatment with sirolimus, an mTOR inhibitor. A brief review of the current literature regarding sirolimus use in vascular malformations, lymphatic malformations, regional overgrowth syndromes, and RASopathies is discussed.
