Radiological diagnosis of spinal arachnoid cysts: A pictorial essay.

Spinal arachnoid cysts (AC) are intraspinal extramedullary loculated cerebral spinal fluid collections. They are relatively uncommon lesions. Spinal AC often cause symptoms such as pain, weakness and radiculopathy. In this pictorial essay we demonstrate the main radiological features of spinal AC, as well as symptoms and complications associated with them. We also describe the main differential diagnoses.

Pons herniation into skull base after cabergoline therapy of giant prolactinoma.

INTRODUCTION: Pons herniation after cabergoline therapy for giant prolactinoma is a complication not documented in literature. CASE REPORT: We report a medium aged patient who developed secondary hemiparesis after 18 months of medical treatment. MRI revealed pons herniation into the clivus. There was improvement with conservative treatment. Secuencial MRIs are presented showing the tumor at the moment of the diagnosis, tumor shrinkage and pons herniation. DISCUSSION: Some studies have shown that a significant and rapid tumor shrinkage resulting from treatment with cabergoline can occur and it is thought that some complications are related with this tumor regression, as in the presented case.

Tendinitis calcificante bilateral del tendón largo del biceps asociado a lesión SLAP / Bilateral calcifying tendinitis of the long tendon of the biceps associated with a SLAP lesion

La tendinitis calcificante es una alteración común relacionada con el depósito de cristales de hidroxiapatita cálcica que suele localizarse alrededor del hombro, especialmente en el tendón supraespinoso. La presentación clínica es variable e incluye dolor e inflamación que a menudo se resuelve espontáneamente. Presentamos un caso de un varón de 48 años con tendinitis calcificante bilateral del tendón largo del bíceps en su inserción en el tubérculo glenoideo superior que se asociaba a lesión del labrum superior y que se confirmó en la artroscopia. Los depósitos cálcicos se resecaron y se reparó la lesión del labrum superior de ambos hombros mediante sutura artroscópica (AU)

Calcifying tendinitis is a common disorder related to deposition of hidroxyapatite crystals, which is most common around the shoulder joint, involving the supraespinosus tendon. It can however, affect almost any tendon at its insertion. Clinical features are variable and include pain and inflammation that often resolves spontaneously. We present a case of bilateral calcifying tendinitis of the long head of the biceps tendon at its insertion on the superior glenoid rim associated with superior labrum antero-posterior tears (SLAP) confirmed by arthroscopy. Calcium deposits were surgically removed and the SLAP lesions were repaired (AU)
