Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic necrotizing inflammation of the small vessels. Central nervous system (CNS) ANCA-associated vasculitis is a rare manifestation of AAV. Three mechanisms of AAV affecting the CNS have been reported which include contiguous granulomatous invasion from nasal and paranasal sinuses, remote granulomatous lesions, and vasculitis of small vessels. Chronic hypertrophic pachymeningitis (CHP) is the meningeal-site involvement in AAV caused by granulomatous inflammation in the dura mater. We present a case of pachymeningitis manifested with slowly progressive cognitive dysfunction, leptomeningeal enhancement on MRI, and necrotic vessels with surrounding inflammation on biopsy. This case represents a rare development of subsequent CNS AAV in a patient with ANCA-associated interstitial lung disease treated with rituximab with a resolution of leptomeningeal enhancement on a follow-up magnetic resonance imaging (MRI).

Occasionally pressure symptoms on adjacent neurovascular structures may be exerted, thereby causing functional impairment. Lipomas rarely grow larger than 5 cm, becoming the so-called giant lipomas, posing a real diagnostic and surgical challenge. We report an unusual case of a 43-year-old Caucasian female with an accidental pelvic ultrasound finding of a giant mass, which was also palpable over the right gluteal region. Interestingly the patient was free of any sciatic nerve compression symptoms. Magnetic resonance imaging (MRI) revealed a soft tissue tumor, partially located in between the external rotator muscles of the hip and the gluteus muscle. The tumor forced up and advanced through the great sciatic foramen into the pelvis. The patient underwent an uneventful complete and safe surgical excision of the gluteal mass, via a wide transgluteal approach. Pathology confirmed lipoma diagnosis. Patient is free from recurrence two years post operatively. Physicians involved in the diagnosis and treatment of gluteal masses should always consider in their differential diagnosis the presence of a sciatic hernia.

PVT in acute cases is usually asymptomatic, whereas chronic cases mostly present as variceal bleeding and splenomegaly. However, cavernous transformation of the portal vein secondary to a long-standing PVT is very rare. Here we present a case of a 28-year-old female who was admitted with complaints of left upper abdominal pain and swelling for four to five years. Using laboratory and radiological examinations, a confirmatory diagnosis of cavernous transformation of a thrombosed portal vein due to protein C and S deficiency was made. The patient was managed through splenectomy with splenorenal shunting along with life-long prescription of anticoagulants.

Cosmetic interventions may traumatize it, resulting in a circulation in the lesion in glabellar region and in the medial aspect of the forehead. This review article aims to synopsise the existing knowledge of the anatomy of the supratrochlear artery in close correlation with minimally invasive cosmetic procedures in the facial area such as soft-tissue filler injections. Their possible adverse effects and their safe application based on the topographic anatomy were included. A literature review was performed in PubMed/Medline online medical database. The superficial course of the supratrochlear artery, as well as the rich, variable anastomotic network that it forms with the supraorbital, angular and dorsal nasal artery raise clinical questions in the case of soft-tissue filler injections in the nasoglabellar and central forehead area. Accidental cannulation of the supratrochlear artery and ultimately, the risk of embolization of the central retinal artery in a retrograde fashion might lead to injury with questionable cosmetic results. Although the risk of complications from the use of soft tissue fillers is considered rare, once happen, the results could be devastating for the quality of life. Thus, the comprehension of the anatomy of the supratrochlear artery is paramount for the health practitioners.

The patients included in the study were classified as Group 1 (FGF23 less then 71 pg/mL, n= 42) and Group 2 (FGF23 ≥ 71pg/mL, n= 46) and the data was analyzed as a statistical significance between the two groups. The presence of atherosclerosis was determined by a Doppler ultrasound for evaluate the carotid artery intima-media thickness (CA-IMT). Intrarenal Doppler spectra were obtained with same Doppler ultrasound to determine the renal resistivity index (RRI) for evaluate graft renal failure. Results A total of 88 kidney transplantation recipients were included in the study. In the multivariate analysis adjusted for age and gender, the eGFR (β =-0.217, p=0.048), CA-IMT (β =0.318, p=0.009) and RRI (β =0.246, p=0.019) parameters were statistically significant, while the remaining parameters were not statistically significant. In the group analysis, Ca (9.6 ± 0.3 vs. 8.8 ± 0,2, p less then 0.05), CA-IMT (0.9 ± 0.2, vs. 0.6 ± 0.3, p less then 0.05) and RRI (0.69 ± 0.04 vs. 0.60 ± 0.01, p less then 0.05) were significantly higher in the patients in group 2 than the patients in group 1.  Conclusion According to our results, FGF23 can be considered as a descriptive biomarker for cardiovascular prognosis and graft function for patients with kidney transplantation.
