Acquired Simple Bone Cyst Associated With Lumbar Spinal Canal Stenosis Progression: A Case Report.

A simple bone cyst (SBC) in the posterior lumbar bone structure is very rare. Here, we report a case of SBC at the L5 lumbar lamina with venous obstruction associated with ligamentum flavum thickening. A 59-year-old woman presented with intermittent claudication due to low back pain and bilateral sciatica.

Intractable hiccup caused by syrinx in Chiari type I malformation. Two cases report.

Background: Intractable hiccups (IH) due to syringomyelia or syringomyelia/syringobulbia associated with Chiari type I malformations (CMI) are extremely rare. Here, we present two patients who presented with IH; one had a CMI with syringomyelia/syringobulbia, and the other, with CMI and syringomyelia.

Case Description: The first patient was an 18-year-old female who presented with IH attributed to a holocord syrinx and syringobulbia involving the right dorsolateral medulla.

Case of lumbar ligamentum flavum hematoma with epidural hematoma resulting in cauda equina compression.

Background: Lumbar ligamentum flavum hematomas (LFHs) are rare. However, when they occur and contribute to epidural cauda equina compression, timely surgical intervention is frequently warranted.

Case Description: A 69-year-old female presented with the left lower extremity sciatica and gait disturbance of 2 weeks' duration that ultimately evolved into a paraparesis/cauda equina syndrome.

A case of mid-thoracic osteoporotic vertebral fracture with the inability to belch syndrome.

Background: Osteoporotic vertebral fractures (OVF) commonly occur at the thoracolumbar junction, but are less frequently encountered in the mid-thoracic region. Here, a 69-year-old female presented with back pain and the new onset of symptoms characterized by the inability to belch.

Case Description: A 69-year-old female presented with back pain.

Leptomeningeal Carcinomatosis After Neoplastic Cerebral Aneurysm Rupture.

Background: Several possible mechanisms exist for the spread of a primary tumor to the leptomeninges in leptomeningeal carcinomatosis. This report describes a case caused by direct bleeding in the subarachnoid space from a neoplastic cerebral aneurysm rupture.

Case Description: A 48-year-old Japanese woman, who was diagnosed with breast carcinoma (pT3 pN2 M0) at the age of 45 years and underwent mastectomy and chemotherapy, was admitted in a coma following a sudden-onset severe headache.
