Pulmonary hyalinizing granuloma (PHG) is a rare disease that usually presents with multiple bilateral pulmonary nodules and characteristic histological findings, with hyalinized collagen lamellae. Because of the absence of characteristic radiologic and clinical features, PHG is usually diagnosed after surgical resection or biopsy. We performed thoracoscopic wedge resection for a pulmonary nodule located in the right lower lobe that proved to be PHG histopathologically. We report two cases along with a review of the literature.

OBJECTIVE: The purpose of this study was to investigate the prevalence and risk factors of ulnar neuropathy at the elbow (UNE) in a rural district in Korea. METHOD: Among the 578 residents in a rural district who participated in the health examination, 450 (116 male, 334 female) adults were randomly selected. A symptom questionnaire and electrodiagnostic studies were used to diagnose UNE. General characteristics, female-related factors, work-related factors and anthropometric measurements were compared between normal and UNE group to identify the risk factors of UNE. RESULTS: Subjects with UNE were 29 (6.4%), symptom without electrodiagnosis findings 23 (5.1%), asymptomatic subjects were 379 (84.2%). Diabetes mellitus, repetitive heavy lifting were risk factors of UNE. CONCLUSION: The prevalence of UNE was 6.4% in a rural district and these data suggest that medical conditions like diabetes mellitus and physical factors like repetitive heavy lifting are risk factors of UNE.

OBJECTIVE: We investigated plantar nerve injuries associated with calcaneal fracture and severity of disability. METHOD: From July, 2001 to June, 2002, twelve patients who had calcaneal fractures with persistent foot pain and paresthesia were included in our study. We examined electromyography for medial and lateral plantar nerve, inferior calcaneal nerve, also evaluated types of calcaneal fracture and severity of pain and disability with nerve injury. RESULTS: The intraarticular types were 13 cases, extraarticular type was 1 case and communited types were 2 cases. In the electromyographic findings, the 9 cases were diagnosed asneuropathy. In a cases with neuropathy, 8 persons complained over moderate degree of pain and all persons complained over moderate degree of walking disability. However one of three persons without neuropathy complained over moderate degree of walking disability. So disability tended to be more severe in cases with neuropathy. CONCLUSION: We think that neuropathy associated with calcaneal fracture is a cause of aggravation of pain and walking disability, and electromyography for nerves of foot will be needed in the calcaneal fracture.

OBJECTIVE: To evaluate the correlation of electrodiagnostic severity, severity of symptom, and clinical severity in carpal tunnel syndrome (CTS). METHOD: The sixty eight patients with documented CTS in outpatient clinic from January, 2000 to June, 2001 were included (9 male, 59 female, averaged age 50.0+/-8.8 years). We evaluated the severity of symptom, functional status of ADL with the Levine' questionnaire, and clinical severity with 3 kinds of examination (thenar atrophy, sensory change, and Phalen's test). The electrodiagnostic severity was classified according to Stevens' classification and compared with the severity of symptom, functional status, and clinical severity. RESULTS: The electrodiagnostic severity was classified into three degrees. Five patients (7.4%) were classified into mild degree, 32 patients (47.1%) moderate degree, 31 patients (45.6%) severe degree. The average of severity of symptom scores were 28.4+/-8.5, 31.8+/-7.4, and 31.8+/-9.1 respectively, and there was no significant difference (p>0.05) between the groups. Functional status scales were 14.2+/-6.7, 15.6+/-5.4 and 18.9+/-7.0 respectively and no significant difference (p=0.07) but there was a tendency that the severer was electrodiagnostic severity, the more decreased functional status scale. The clinical severity showed a significant correlation with the electrodiagnostic severity (p<0.05). CONCLUSION: The electrodiagnostic severity has a significant correlation with the clinical severity, but not with the severity of symptom, the functional status in CTS.

OBJECTIVE: To compare treatment effects of translaminar epidural steroid injections (TLESIs) only and selective nerve root injections (SNRIs) with TLESIs in lumbosacral spinal stenosis. METHOD: Thirty-four patients diagnosed with magnetic resonance imaging (MRI), somatosensory evoked potential (SEP) and electromyography (EMG) were included. 16 patients who had somatosensory pathway dysfunction or abnormal spontaneous activity received combined SNRIs with TLESIs and 20 patients received only TLESIs. The visual analogue scale (VAS) and functional rating index (FRI) were measured before injection, 1 week and 3 months after 3 times injection. RESULTS: The mean values of VAS before injection, 1 week and 3 months after 3 times injection were 7.55, 3.22, 3.61 in only TLESIs and 7.37, 2.06, 2.31 in SNRIs with TLESIs. The mean values of FRI before injection, 1 week and 3 months after 3 times injection were 25.16, 16.00, 15.83 in only TLESIs and 22.50, 8.37, 8.31 in SNRIs with TLESIs. In the mean values of VAS and FRI were significantly lower SNRIs with TLESIs than only TLESIs (p<0.05). CONCLUSION: Combined SNRIs with TLESIs were more effective treatment for reduction of pain and improvement of function than only TLESIs in lumbosacral spinal stenosis.

OBJECTIVE: To investigate the usefulness of computed tomography venography (CTV) for evaluation of leg swelling, especially deep vein thrombosis (DVT), in rehabilitation patients. METHODS: A hundred twenty-three patients, who had performed CTV performed because of suspected DVT in our clinic, were enrolled. We performed chart reviews retrospectively and categorized CTV findings as follows: DVT distal to inguinal ligament and no compression lesion; DVT proximal to inguinal ligament and no compression lesion; DVT distal to inguinal ligament and anatomical variant (for example, May-Thurner syndrome); DVT due to compression of mass (cancer or cyst); DVT and other incidental abnormal finding; and no DVT and other possible causes of leg swelling. RESULTS: DVTs were found in 65 (53%) patients. DVTs were found at distal level (thigh or lower leg) to inguinal ligament in 47 patients. DVTs were found at proximal to inguinal ligament, usually undetectable with duplex ultrasonography, in 6 patients. DVTs caused by external compression, such as femoral vein and cancer mass, were found in 12 patients (10%), which are also not easily detected with duplex ultrasonography. Other various causes of leg edema without DVT were found in 22 (18%) patients. CONCLUSION: CTV can evaluate more extensively venous problems in the pelvis and abdomen and detect other possible causes of leg swelling. Therefore, CTV can be a useful tool not only for easy detection of DVT but also for evaluating differential diagnosis of leg edema in rehabilitation patients.

OBJECTIVE: To compare the long-term effect and safety of an epidural steroid injection in spinal stenosis patients, with or without local anesthetics. METHODS: Twenty-nine patients diagnosed with spinal stenosis were included and randomly divided into two groups. Translaminar epidural and selective nerve root spinal injection procedures were performed using steroids mixed with local anesthetics or normal saline. The effects of spinal injection procedures were measured with visual analogue scale (VAS) and functional rate index (FRI). These measurements were performed before injection, at 1 month after injection and at 3 months after injection. The occurrence of side effects was investigated each time. RESULTS: The VAS and FRI scores were significantly reduced in both the local anesthetics group and normal saline group at 1 and 3 months after the injection. However, there was no significant difference in VAS and FRI score reduction between the two groups each time. Side effects are not noted in both groups. CONCLUSION: The spinal injection procedures using steroids mixed either with local anesthetics or normal saline have an effect in reducing pain and improving functional activities. However, there was no significant difference between the two groups in relation to side effects and the long-term effects of pain and function.

Kikuchi's disease is a self-limiting benign disease characterized by cervical lymphadenopathy, but it can be mistaken for malignant disease, and when involved lymph nodes are unusually located, diagnosis can be more difficult. The authors report the case of a 19-year-old man with Kikuchi's disease, who had isolated intraabdominal lymphadenopathy and increased 18-fluoro-deoxyglucose (FDG) uptake in positron emission tomographycomputed tomography (PET-CT). Although its incidence is extremely rare, intra-abdominal Kikuchi's disease with increased FDG uptake in PET-CT image should be considered in the differential diagnosis when constitutional symptoms mimic those of malignant lymphoma.

Piriformis syndrome (PS) is an uncommon neuromuscular disorder caused by the piriformis muscle (PM) compressing the sciatic nerve (SN). The main symptom of PS is sciatica, which worsens with certain triggering conditions. Because the pathophysiology is poorly understood, there are no definite diagnostic and therapeutic choices for PS. This case report presents a young woman who mainly complained of bilateral leg weakness. Electromyography revealed bilateral sciatic neuropathy and magnetic resonance imaging confirmed structural lesions causing entrapment of the bilateral SNs. After a laborious diagnosis of bilateral PS, she underwent PM releasing surgery. Few PS cases present with bilateral symptoms and leg weakness. Therefore, in such cases, a high level of suspicion is necessary for accurate and prompt diagnosis and treatment.

Leptomeningeal metastasis (LMM), also referred to as leptomeningeal carcinomatosis, results from diffuse infiltration of the leptomeninges by malignant cells originating from extra-meningeal primary tumors. It occurs in approximately 5%-10% of patients with solid tumor. Among solid tumors, the most common types leading to infiltration of the leptomeninges are breast cancer, lung cancer, and melanoma. Patients with LMM may present various signs and symptoms. Herein, we report a rare case with initial presentation of isolated chest wall pain. Computed tomography of the chest with contrast revealed a 2.5-cm nodule over the left upper lung. Biopsy confirmed the diagnosis of adenocarcinoma. Later, cerebrospinal fluid cytology exam also confirmed leptomeningeal seeding. It is rare for leptomeningeal carcinomatosis patients to present with chest wall pain. Therefore, a high index of suspicion is mandatory for accurate and prompt diagnosis.
