Cystic adventitial disease of the popliteal artery: A case report with review of literature.

INTRODUCTION AND IMPORTANCE: Cystic adventitial disease (CAD) is a rare vascular disorder marked by occlusion stemming from the development of a cystic mass within the outer (subadventitial) layer, with a predominant impact on the popliteal artery. The significance of the case presented herein lies in shedding light on a distinct clinical manifestation involving a 40-year-old man who exhibited sporadic calf claudication during ambulation. This instance contributes to the broader understanding of CAD and its diverse clinical presentations, emphasizing the need for further exploration and awareness within the medical community. CASE PRESENTATION: A 40-year-old man, with no significant past medical history, was referred to the cardiovascular department for the evaluation of a new onset of left calf pain persisting over the past three months. An arterial lower limb Doppler ultrasound was performed, revealing a focal hypoechoic image around the popliteal artery with a regular arterial wall, indicative of extrinsic compression. This resulted in significant stenosis of the popliteal artery during plantar flexion of the foot. The diagnosis of CAD of the left popliteal artery was established after limb computed tomography angiography, and a complete resection of the cyst was scheduled. The postoperative course was uneventful, with the patient experiencing relief from left calf claudication. CLINICAL DISCUSSION: CAD is an uncommon vascular anomaly, representing merely 0.1 % of all vascular conditions. This condition predominantly afflicts men aged between 40 and 50 years old. The etiology of CAD remains a subject of debate, with pathological findings typically involving intramural cysts containing gelatinous material between the media and the adventitia. Surgical intervention becomes necessary when symptoms arise. CONCLUSION: CAD of the popliteal artery, though rare, is a significant contributor to peripheral vascular insufficiency in young patients without typical atherosclerotic risk factors.

Desmoplastic infantile ganglioglioma.

The term desmoplastic infantile ganglioglioma was coined by VandenBerg et al in 1987. In their first report these authors referred to a rare, distinct brain tumor. About 60 cases of desmoplastic infantile ganglioglioma have been described in the literature since its first description. We report a case of a 6-year-old girl who was admitted for seizure without family history. Magnetic resonance imaging scan showed a hypodense area in the right temporal region. A right temporal craniotomy was performed and the tumor was excised. The pathologic examination revealed the diagnosis of desmoplastic infantile ganglioglioma.

Unusual presentation of sarcoidosis: solitary intracranial mass lesion mimicking an intracranial neoplasm: a case report.

Sarcoidosis is a multisystem disease of unknown cause and with a worldwide distribution. Involvement of the central nervous system occurs in a relatively small number of patients with sarcoidosis. Isolated neurosarcoidosis without signs of systemic disease however is a rare. In this report, we present an unusual case of neurosarcoidosis with intra cranial mass mimicking radiologically a glioma. Pathological examination revealed intraparenchymatous necrotising granulomatous lesions. After clinicopathological correlation, the diagnosis of a necrotizing cerebral granulomatosis (neurosarcoidosis) with atypical systemic involvement was made. Because of its non-specific clinical presentation and neuroradiological imaging characteristics, intracranial neurosarcoidosis remains a very difficult diagnosis, particularly in the absence of systemic signs of the disease.
