A 32-year-old male came to the emergency room with a crescentric 4x11 cm tissue defect at the right temporo-parietal region. Brain tomography showed a tissue defect in the right parietal region but bone integrity was preserved. A free flap procedure was performed to protect the cranial bones. Two months after discharge from the hospital, he presented with a draining dirty wound that appeared ne...

Primary bone lymphoma (PBL) is a relatively uncommon entity. However, involvement of the cranial vault is an unusual manifestation of aggressive non-Hodgkin's lymphoma. We report the case of a 42-year old immunocompetent woman who presented with an enlarging mass involving the right parietal bone. Magnetic resonance imaging (MRI) of the brain revealed an expansive tumor that affects the right p...

Magnetic resonance imaging of the brain demonstrating peripheral enhancement of the scalp abscess alongside noticeable enhancement of the adjacent soft tissues, pathological bone, and underlying pachymeningeal layer enhanced on a coronal T1W slice (left) with a clear intra-osseous edematous edema in keeping with osteomyelitic changes isolating a central bone sequestrum, communicating ...

BACKGROUND Calvarial lesions are often detected incidentally in routine radiology. Most lytic lesions of the skull are benign. Enlarged parietal foramina are benign lesions caused by deficient intramembranous ossification. CASE REPORT An 11 month-old female patient was admitted with a mass on the right of the back of the head. Physical examination showed a soft 5 cm mass area with no palpable...

Although thyroid carcinoma is a relatively common form of malignancy, metastatic spread to the skull is rare. Here, we report a case of papillary thyroid carcinoma with frontal and parietal metastasis. A 61-year-old Chinese woman presented with a one year history of a growing mass on the center of the frontal and parietal bone, initially thought to be meningioma. Biopsy of the skull base mass a...

objective: the aim of present study was to evaluate the quality, density and thickness of newly formed bone in experimental defects treated with combi-pack®, bio-oss® and biostite®. materials and methods: eight new zealand white rabbits were included in this randomized,blinded study. four equal 3×6 mm bone defects were created on the frontal and parietal bones of each animal and three were imme...

A 45-year-old lady underwent right fronto-parietal craniotomy and subtotal excision of a parasagittal meningioma. Bone flap was not replaced as it was infiltrated by the tumor. In the postoperative period she developed episodes of altered sensorium associated with worsening of left hemiparesis and a sunken scalp at the site of bone defect. Computed tomography (CT) of brain showed sunken scalp f...

BACKGROUND The mechanical properties of 1-2-year-old pediatric cranial bones and sutures and their influential factors were studied to better understand how the pediatric calvarium reacts to loading. MATERIAL AND METHODS Cranial bone and suture specimens were extracted from seven fresh-frozen human infant cadavers (1.5±0.5 years old). Eight specimens were obtained from each subject: two front...
