Objective : There is a lack of knowledge regarding whether decompression is necessary in treating patients with epidural spinal cord compression (ESCC) grade 2. The purpose of this study was to compare the outcomes of minimally invasive surgery (MIS) without decompression and conventional open surgery (palliative laminectomy) for patients with hepatocellular carcinoma (HCC) spinal metastasis of ESCC grade 2. Methods : Patients with HCC spinal metastasis requiring surgery were retrospectively reviewed. Patients with ESCC grade 2, medically intractable mechanical back pain, a Nurick grade better than 3, 3-6 months of life expectancy, Tomita score ${\geq}5$, and Spinal Instability Neoplastic Score ${\geq}7$ were included. Patients with neurological deficits, other systemic illnesses and less than 1 month of life expectancy were excluded. Thirty patients were included in the study, including 17 in the open surgery group (until 2008) and 13 in the MIS group (since 2009). Results : The MIS group had a significantly shorter operative time ($94.2{\pm}48.2minutes$ vs. $162.9{\pm}52.3minutes$, p=0.001), less blood loss ($140.0{\pm}182.9mL$ vs. $1534.4{\pm}1484.2mL$, p=0.002), and less post-operative intensive care unit transfer (one patient vs. eight patients, p=0.042) than the open surgery group. The visual analogue scale for back pain at 3 months post-operation was significantly improved in the MIS group than in the open surgery group ($3.0{\pm}1.2$ vs. $4.3{\pm}1.2$, p=0.042). The MIS group had longer ambulation time ($183{\pm}33days$ vs. $166{\pm}36days$) and survival time ($216{\pm}38days$ vs. $204{\pm}43days$) than the open surgery group without significant difference (p=0.814 and 0.959, respectively). Conclusion : MIS without decompression would be a good choice for patients with HCC spinal metastasis of ESCC grade 2, especially those with limited prognosis, mechanical instability and no neurologic deficit.

Purpose: Bone metastasis from stomach cancer occurs only rarely and it is known to have a very poor prognosis. This study examined the clinical characteristics and prognosis of patients who were diagnosed with stomach cancer and bone metastasis. Materials and Methods: The subjects were 19 patients who were diagnosed with stomach cancer at Hanyang University Medical Center from June 1992 to August 2010 and they also had bone metastasis. The survival rate according to many clinicopathologic factors was retrospectively analyzed. Results: 11 patients out of 18 patients (61%) who received an operation were in stage IV and the most common bone metastasis location was the spine. Bone scintigraphy was mostly used for diagnosing bone metastasis and PET-CT and magnetic resonance imaging were used singly or together. The serum alkaline phosphatase at the time of diagnosis had increased in 12 cases and there were clinical symptoms (bone pain) in 16 cases. Treatment was given to 14 cases and it was mostly radiotherapy. There were 2 cases of discovering bone metastasis at the time of diagnosing stomach cancer. The interval after operation to the time of diagnosing bone metastasis for the 18 cases that received a stomach cancer operation was on average $14.9{\pm}17.3$ months and the period until death after the diagnosis of bone metastasis was on average $3.8{\pm}2.6$ months. As a result of univariate survival rate analysis, the group that was treated for bone metastasis had a significantly better survival period when the bone metastasis was singular rather than multiple, as compared to the non-treatment group, yet both factors were not independent prognosis factors on multivariate survival analysis. Conclusions: An examination to confirm the status of bone metastasis when conducting a radio-tracer test after the initial diagnosis and also after an operation is needed for stomach cancer patients, and bone scintigraphy is the most helpfully modality. Making the diagnosis at the early stage and suitable treatments are expected to enhance the survival rate and improve the quality of life even for the patients with bone metastasis.

Spinal intradural hemangiopericytoma is a very rare tumor and can be characterized by massive bleeding during surgeries, frequent recurrence, and metastasis. However, definite radiologic differential points of hemangiopericytoma are not known. We describe an unexpected hemangiopericytoma case with large bleeding and management of the tumor. A 21-year-old man visited complaining of progressive neck pain and tingling sensation in both hands. Magnetic resonance imaging of his spine revealed C1-2 ventral intradural mass. When the dura was opened, the intradural tumor was placed behind spinal accessary nerves. The tumor was partially exposed only after some accessary nerves had been cut. When internal debulking was performing, unexpected bleeding was noted and it was difficult to control because of narrow surgical field and hypervascularity. Intraoperative spinal angiography and embolization were performed. The tumor was completely removed after embolization. Pathological diagnosis was consistent with hemangiopericytoma. When surgeons meet a flesh-red tumor that bleeds unexpectedly during surgery, hemangiopericytoma may be considered. When feeder control is hard due to reciprocal location of spinal cord, the tumor, and feeders, intraoperative angiography and embolization may be a possible option.

A 26-year-old man with renal cell carcinoma underwent $^{99m}Tc$-HDP bone scintigraphy for detecting bony metastasis after left total nephrectomy for renal cell carcinoma. $^{99m}Tc$-HDP bone scintigraphy showed small hot lesion in the first lumbar spine. About 12 months later, he underwent spinal MRI for lower back pain. A large mass was seen around spinous process of the first lumbar spine (L1) on spinal MRI and confirmed as metastatic renal cell carcinoma by bone biopsy. $^{99m}Tc$-HDP bone scintigraphy and $^{18}F$-FDG PET/CT were underwent for further evaluation. $^{99m}Tc$-HDP bone scintigraphy showed cold lesion in the first lumbar spine which was initially hot and newly developed hot lesion in the twelfth thoracic spine, and which were shown as hypermetabolic lesions in $^{18}F$-FDG PET/CT. We report a case of bony metastasis from renal cell carcinoma which is changed from hot lesion to cold lesion in $^{99m}Tc$-HDP bone scintigraphy and compare with $^{18}F$-FDG PET/CT.

The objective of this study is to report an accidental detection of colorectal cancer (CRC) metastasis to spine during conservative treatment for lumbar disc herniation. We treated a 65-year-old female who was diagnosed with lumbar disc herniation on September 2019 by acupuncture, pharmacopuncture, cupping treatment, chuna manual therapy, herbal medicine treatment, medicine treatment and physical therapy. After that we analyzed medical record from December 12, 2019 to February 11, 2020. The patient was diagnosed with CRC and received tumor resection in 2014. After 2 times of chemotherapy, she arbitrarily interrupted the treatment. Since she stated that CRC treatment was terminated, we had difficulty in finding connection between symptom and CRC. During the treatment period, compression fracture at L3 body was found, which was caused by CRC metastasis. Rigorous question, appropriate radiological and clinical tests are required to patients who have history of malignant tumor.

An intramedullary spinal cord metastasis (ISCM) rarely develops in systemic cancer but is indicative of a poor prognosis. A 56-year-old man was admitted due to weakness of the lower extremities. He had received radiotherapy 3 months prior for a brain metastasis that had developed 1 year after achieving a complete response from chemotherapy for extended stage small cell lung cancer. Although the brain lesion had improved partially, ISCM from the cervical to lumbar-sacral spinal cords, which was accompanied by a leptomeningeal dissemination, was diagnosed based on magnetic resonance imaging of the spine and cerebrospinal fluid cytology. Finally, he died of sudden cardiac arrest during treatment. This is the first case of ISCM involving the whole spinal segments. Physicians should be aware of the subsequent development of ISCM in lung cancer patients with a previously known brain metastasis who present with new neurological symptoms.

Wilms' tumor is the most common malignant renal tumor in childhood. The brain metastasis of a Wilms' tumor with anaplastic histopathology is rare. We present the case of an 8-year-old girl with Wilms' tumor, who presented with multiple brain metastases 5 years after her primary diagnosis. The brain masses were diagnosed after a generalized tonic-clonic seizure attack. The big solid mass in the cerebellum was resected, and whole-brain radiotherapy was performed, after which, she succumbed to her disease. In the case of clinical suspicion, cranial surveillance should be included in the routine clinical work-up for Wilms' tumor. Combined aggressive therapy (surgery+radiotherapy+chemotherapy) should be applied whenever possible, for both better survival and palliative aspects.

Occult papillary adenocarcinoma of the thyroid is known to be indolent, slow metastatic, and has a good prognosis. Occult thyroid carcinoma presenting as a blood-borne metastasis without obvious cervical lymph node involvement is extremely rare. A 65-year-old male patient was visited for hoarseness, dysphagia, and shortness of breath. Bronchoscopy with biopsy revealed a papillary carcinoma of thyroid by immunohistochemical staining. Head & neck CT revealed that involving both the upper esophagus and the posterior tracheal wall, extending into the mediastinum along the upper thoracic spine at $T_1-T_2$. We have experienced a rare case of occult papillary carcinoma which invaded the trachea, esophagus and fascia of thoracic spine. Treatment was initiated with radioactive iodine and external bean therapy.
