An unusual case of solitary benign schwannoma of the foot is presented. Clinical examination, magnetic resonance imaging, and intraoperative findings all confirm the suspicion of a ganglion cyst. After attempted aspiration failed to produce any aspirate, excisional biopsy was performed. The pathology report confirms schwannoma with hematoxylin and eosin stain and subsequently reaffirmed with positive S100 protein stain. Even though schwannoma of the foot had been reported in the literature, this was an unusual case, as the lesion was presented as a superficial, ganglion cyst–like lesion on the bottom of the foot.

This paper reports an unusual case in which aseptic meningitis presented with sudden sensorineural hearing loss (SSNHL) associated with intralabyrinthine haemorrhage (ILH). A seven-year-old girl presented with sudden right-sided hearing loss with dizziness. She did not have a previous history of bleeding disorders. This child was assessed using audiograms and magnetic resonance imaging (MRI). The patient's hearing loss was irreversible. Steroid therapy was not effective. SSNHL associated with ILH can be one of the negative prognostic factors in children.

ABSTRACTWe report an unusual case of unilateral limb pseudo hypertrophy in a 21-year-old lady who developed progressive enlargement of the right calf followed by thigh in association with chronic leg pain. Magnetic resonance imaging (MRI) of the affected limb confirmed enlargement of various muscles. Electromyography revealed neurogenic features consistent with S1 radiculopathy. MRI of the lumbosacral spine showed tethered cord with a lipoma infiltrating multiple sacral roots. Our case illustrates that muscular pseudo hypertrophy may follow chronic denervation as a consequence of spinal neural compressive disease. The various mechanisms postulated for this distinct condition are outlined.

Objectives: Tendinopathy of the flexor hallusis longus tendon is common in the athletes. This case is intended to be reported diagnose and treatment ganglion cyst contiguity of the flexor hallucis longus tendon that located atypical region and adversely affect the athlete's training program. Methods: 25-year-old male national swimmer was assessed with a left ankle pain. He had an intensive training program in the pool using pallets at the everyday. Pain in the left ankle was localized posterior and distal of the medial malleolus . Ankle range of motion and muscle strength was full. Neurovascular examination was normal. Radiography with anterior posterior, lateral and oblique analysis was not any unusual finding. In the evaluation with magnetic resonance imaging, thickening of the tendon sheath and effusion around the flexor hallucis longus was revealed and tendon integrity was exact. Results: Conservative treatment was planned. It was applied non-steroidal anti-inflammatory medicine, modification of the training (without or low weight pallet), platelet rich plasma (two weeks, two times peer weeks). During the six-month follow-up the patient's symptoms improved, but with the increased intensity of training at follow-up complaints started again. Professional athletes who did not respond adequately to conservative treatment surgical exposure were planned. Patient is approached the flexor hallucis longus musculotendinous junction from the posteromedial ankle at the level of the posterior talar tubercles. During the tendon exposure cyst was found at the level of talocalcaneal joint. Excision of the cyst was achieved; its size was 5x5 mm, looking transparent, well defined and soft consistency. Tenolysis is accomplished from superior to inferior to the level of the superior calcaneus. A histopathologic examination result of the cyst consistent with ganglion cyst was detected. Sport-specific training program started at the 6 weeks. There was no recurrence during the 6 months follow-up. Conclusion: Tendon associated ganglion cyst is not usual although flexor hallucis longus tendinopathy is common in athletes. External pressure causes in addition to the overuse injuries should be remembered in the differential diagnosis of posterior ankle and medial arch pain. Clinical suspicion and magnetic resonance imaging are valuable in establishing the diagnosis. Tenolysis and excision of the associated mass has proven to be a relatively safe and successful procedure especially in highly demanded elite athletes.

Abstract We describe an unusual case of unifocal eosinophilic granuloma of the spine in a 38-year-old woman who presented with spinal cord compression. After 2 years of back pain, x-ray films of the spine were normal, but computed tomography and magnetic resonance imaging demonstrated a lytic lesion of the 1st lumbar vertebral body with cephalic extension in the epidural space. The lesion was later confirmed at operation to be an eosinophilic granuloma spreading into the surrounding tissues.

✓ The authors present an unusual case of intramedullary arachnoid cyst diagnosed in a patient after the lesion was resected. A wide decompressive surgery was performed and the lesion removed. Histopathological findings were consistent with the diagnosis of arachnoid cyst. Postoperatively the patient exhibited marked improvement in neurological status. To the best of the authors' knowledge, there is no case report of intramedullary arachnoid cyst reported in the literature. With the advent of newer neuroimaging modalities such as magnetic resonance imaging the number of cases of intramedullary arachnoid cysts encountered in the future may increase.

Quadriceps tendon rupture usually occurs in adults and is rare in children. A six-year-old boy was playing at home and had a fall. He was unable to extend his right knee but there was no gap felt over the patella tendon or quadriceps. He was first seen by a family doctor and presented late to the surgeon three months after the injury. Radiographs and ultrasound were performed. The magnetic resonance imaging confirmed the findings of partial quadriceps tear. The patient was put in a cylinder case with the knee in extension for two months. Six months post-injury, he regained full range of motion without any complications. We present an unusual case of partial quadriceps tear in an otherwise healthy six-year-old boy that was treated successfully despite a delayed presentation. Besides a high index of suspicion, magnetic resonance imaging is a good modality to detect partial quadriceps tear in children.

Abstract Background Angiomyolipoma (AML) is a common, chronic disease usually localized in kidney and liver organs; but occurring frequently outside the kidney or liver. Case presentation We describe an unusual case of a 62-year-old female patient with AML in the middle ear. She presented with left earache, tinnitus and hearing loss. Preoperative computed tomography and magnetic resonance imaging seemed to reveal a middle ear cholesteatoma. The patient underwent surgical resection of this lesion, and the AML was finally confirmed by histopathological examination. The patient was discharged on the 8th postoperative day and did not seek further treatment. Conclusions Extraperitoneal AML is rare and accurately identified by histopathology. The recommended management is surgery for AML in the middle ear.

e14666 Background: Magnetic Resonance Imaging (MRI) of pelvis stratifies patients (pts) with rectal cancer (ca) according to locally advanced disease (dx) & risk of local recurrence. By determining the extent of lymph node (LN) positivity, it enables the appropriate selection of pts for neoadjuvant therapy (NAT) prior to curative surgical resection (Sx). We assessed our institution’s experience of NAT versus upfront Sx in stage I-III rectal ca to ascertain the utility of MRI as a predictive tool in LN status evaluation. Methods: We retrospectively reviewed a prospectively maintained database for all pts with a diagnosis of stage I-III rectal ca from January 2006 to September 2012 in a specialist colorectal cancer centre. We analysed data with respect to preoperative MRI staging & definitive histopathological confirmation of LN stage. Results: A total of 210 pts were identified that had Sx for rectal ca with curative intent. Of these, 112 pts received NAT while 98 had upfront Sx. Of those who proceeded directly to Sx, there were 41 females & 57 males. Average age in this group was 73.4 years (range 33 -90). LN staging by MRI was accurate in 45.9% (n=45). LN status could not be evaluated (Nx) in 17.3% (n=17). In 19.4% (n=19) more advanced LN staging was apparent on histology while in 17.3% (n=17) LN stage was deemed more aggressive by MRI. Of those who had NAT, there were 75 males & 37 females. Average age was 62.3 years (range 26-82). In this cohort, 81.3% (n=91) had both a preoperative MRI & pathology report available for comparison. MRI in this group matched histology in 61.5% (n=56). Nx was recorded in 3.3 % (n=3). In 17.6% (n=16) more aggressive LN involvement was evident at histology while 17.6% (n= 16) had less advanced dx at tissue sampling. Overall in this study, MRI accurately predicted LN status in 53.4% (n=101). Conclusions: While MRI is a valuable tool in determining those pts with rectal ca that would benefit from NAT, its predictive value has limitations. With further analysis of the dataset at our institution, we aim to identify other factors involved & create a predictive nomogram for the rectal ca pt with locally advanced dx. We plan to validate this work by including data from other Irish cancer centres.
