We experienced a case of giant cell tumor arising from the right 2nd rib in the diagnostic and therapeutic thoracotomy at our department of Thoracic and Cardiovascular Surgery, Chungnam Univ. Hospital in May 3rd, 1991. The reports of this tumor are very rare and are known to have the incidence of 1 percent or less of all giant cell bone tumor. The tumor of the right 2nd rib, infant head-sized, covered with parietal pleura was invaded into the vertebra on operation finding. The tumor was resected partially[three fourths] and revealed to be the giant cell tumor on pathologic finding. At now, the patient is taking the radiotherapy to achieve the therapeutic goal to the remnant tumor.

Intracranial involvement in multiple myeloma patients takes up around 1%, and is usually known to be present in the parietal bone or skull base in cases of skull vault involvement, while it presents in the dura and parenchyma in cases of intracranial involvement. Primary pachymeningeal invasion is even rarer with extremely rapid progression and very poor prognosis. It is our intent to report a case in which we had to differentiate multiple myeloma with other metastatic tumors, lymphoma, and leukemia with intracranial involvement. Our patient showed an osteolytic lesion of the skull with dural involvement and subdural mass formations.

Three dimensional computed tomographic images were obtained in two cases with trauma. The first case of a 3 year-old male Maltese, with ataxia and head tilting due to head trauma was referred to veterinary medical teaching hospital, Seoul National University. Remarkable findings were not found on survey radiographs. With the help of three-dimensional reconstruction computed tomographic imaging, parietal and occipital bone fracture was identified. The second case of 4 month-old female Yorkshire terrier with left forelimb lameness was referred right after trauma. Survey radiography showed obvious incongruity of the elbow joint. Lateral and medial condyle of the left humerus fracture and lateral displacement of the left ulna were apparent in three-dimensional computed tomographic image. It was considered that three-dimensional computed tomography could be used as an aid modality for the exact evaluation of extends and degree of fracture as well as planning of orthopedic surgery.

Intradiploic epidermoid cysts, like epidermoid cysts in other cranial locations, are rare. Approximately 100 intradiploic epidermoids have been reported, involving all of the cranial bones in proportion to their relative sizes. Over half erode through both tables of the cranium, creating variably sized areas of unprotected brain beneath the soft tumor. We report a case of an intradiploic epidermoid cyst of the right parietal bone that was found after minor head trauma.

Objective : Traditionally, staged surgery has been preferred in the treatment of compound comminuted depressed fracture (FCCD) after traumatic brain injury (TBI) and involves the removal of primarily damaged bone and subsequent cranioplasty. The main reason for delayed cranioplasty was to reduce the risk of infection-related complications. Here, the author performed immediate reconstruction using a titanium mesh in consecutive patients with FCCD after TBI, reported the surgical results, and reviewed previous studies. Methods : Nineteen consecutive patients who underwent single-stage reconstruction with titanium mesh for FCCD of the skull from April 2014 to June 2018 were retrospectively analyzed. The demographic and radiological characteristics of the patients with FCCD were investigated. The characteristics associated with surgery and outcome were also evaluated. Results : The frequency of TBI in men (94.7%) was significantly higher than that in women. Most FCCDs (73.7%) occurred during work, the rest were caused by traffic accidents. The mean interval between TBI and surgery was 7.0±3.9 hours. The median Glasgow coma scale score was 15 (range, 8-15) at admission and 15 (range, 10-15) at discharge. FCCD was frequently located in the frontal (57.9%) and parietal (31.6%) bones than in other regions. Of the patients with FCCDs in the frontal bone, 62.5% had paranasal sinus injury. There were five patients with fractures of orbital bone, and they were easily reconstructed using titanium mesh. These patients were cosmetically satisfied. Postoperatively, antibiotics were used for an average of 12.6 days. The mean hospital stay was 17.6±7.5 days (range, 8-33). There was no postoperative seizure or complications, such as infection. Conclusion : Immediate bony fragments replacement and reconstruction with reconstruction titanium mesh for FCCD did not increase infectious sequelae, even though FCCD involved sinus. This suggests that immediate single-stage reconstruction with titanium mesh for FCCD is a suitable surgical option with potential benefits in terms of cost-effectiveness, safety, and cosmetic and psychological outcomes.

Samples were obtained from broodstork in May, 1998, while naturally fertilized embryos were maintained and the process of skeletal development was observed from larvae and juveniles. Prelarvae immediately after hatching showed an average total length of $5.38{\pm}0.41mm$ (n=10), premaxillary and dentary were ossified, parasphenoid was ossified in the cranium, and centrum and caudal bone did not ossify. Prelarvae showed ossification with maxillary, articular and epihyal and branchiostegal rays of hyoid arch were ossified at 5 days after hatching with an average total length of $6.40{\pm}0.39mm$ (n=10). The vertebrae began to ossify in the direction of the tail, and neural spine began to ossify above the ossified vertebra. Postlarvae showed ossification of lateral ethmoid, parietal, and caudal skeleton in the cranium when the average total length was $7.30{\pm}0.12mm$ (n=10) in 8 days after hatching. At 22 days after hatching, postlarvae ossified maxillary in the cranium, and ossified endopterygoid and ectopterygoid, etc. in the palate, when the average length of $11.1{\pm}1.27mm$ (n=10). At 32 days after hatching, with the average length was $12.8{\pm}1.97mm$ (n=10), caudal skeleton had one additional epural bone ossification, resulting in ossification of a total of 3 epural bone to complete ossification of all spicules.

A 5-month-old female domestic short-haired cat presented with a history of seizure episodes for two months following an animal bite injury to the head. There were no remarkable findings on physical and neurological examination or blood analysis. Computed tomography revealed a fracture of the left parietal bone with an inward displacement of the bone fragment while magnetic resonance imaging revealed an enlarged temporal horn of the left lateral ventricle and a pseudomeningocele compressing the adjacent cerebral parenchyma. Subsequently, cerebrospinal fluid analysis results were normal. The patient was diagnosed with traumatic brain injury (TBI), with subsequent post-traumatic hydrocephalus (PTH) and pseudomeningocele. Despite treatment with phenobarbital and levetiracetam, seizures were not sufficiently controlled. Craniectomy for bone fragment removal and duraplasty were performed after a week. The patient then returned to normal condition with no further seizure activity. On repeated MRI two months after discharge, the hydrocephalus of the lateral ventricle and pseudomeningocele were enlarged; however, the patient maintained a good clinical status without any neurological signs. To the best of our knowledge, PTH and intracranial pseudomeningoceles have not yet been reported in cats. PTH and pseudomeningocele are among the complications of TBI and may not have any significant relevance with the clinical signs in this case. Thus, to broaden our knowledge about PTH and pseudomeningocele in cats, we describe serial changes in the clinical findings of this cat over the treatment period.

상악골 악성종양의 경우 적출 후 골편들을 이식해 상악동 전체를 재건하는 경우는 재발이 많아 잘 시행하지 않는다. 이러한 이유로 안와하연의 재건을 통해 안구 및 안면윤곽만을 재건하는데, 저자들이 시행한 혈행화된 부분 두께의 골이식(vascularized split thickeness calvarium)은 술기방법에 있어 골피판이 혈관경에서 쉽게 분리되는 성질이 있어 시행에 주의가 필요하고 혈관경을 포함한 temporalis muscle이 부피감을 주므로 미용상 불리한 점이 있는 반면에 골편의 높은 생존율이 보장된다는 장점과 공여부의 합병증이 적다는 장점을 가진다. 또한 술후 복시 현상이나 안구함몰이 관찰되지 않았다는 점이 합리적인 술기임을 지지해준다. 따라서 측두동맥 및 정맥을 혈관경으로 하는 혈행화된 두정골 부분층 이식술은 안와하벽을 재건하는데 있어 안전하게 시행가능 한 술기였음을 보고하는 바이다.
